modify bootloader dram start address, swap app bss and data segments
Modify bootloader dram_seg from address 0x3ffc0000 to 0x3fff0000, len from 0x20000 to 0x10000.
Also put app .data before .bss, to reduce the chance .data collides with ROM bootloader stack.
See merge request !375
This change reduces chances that a large .bss segment will push .data all the way into
0x3ffe1320 — 0x3ffe5320 range where the bootloader stack is, creating a problem when
bootloader will be loading application into memory.
With this change, .data would need to be at least 200k big to cause problems.
Modify bootloader dram_seg from address 0x3ffc0000 to 0x3fff0000, len from
0x20000 to 0x10000. Please be notified that this is just a workaround for
fixing app data overwrite bootloader data issue!

GPIO driver: add per-pin interrupt handlers
1. add ISR handler apis so that users of different layers can hook their own isr handler on different GPIO.
Audio project has different software layers, they need different gpio isr handler for layer instead of processing all GPIO interrupts in one handler.
If this kind of calling a handler from isr is not proper, please kindly point out.
2. add gpio example code.
3. update gpio doc.

Starting the ULP using SENS_SAR_START_FORCE_REG doesn’t disable clock gating of RTC fast clock.
When SoC goes into deep sleep mode, RTC fast clock gets gated, so ULP can no longer run.
Instead, it has to be started using the timer (RTC_CNTL_ULP_CP_SLP_TIMER_EN bit).
When ULP is enabled by the timer, clock also gets enabled.
This change allows setting pin configuration for EXT1 wakeup depending on the state of RTC_PERIPH power domain:
- if peripherals are enabled (due to another wakeup mode, or due to esp_deep_sleep_pd_config call), we can keep internal pullups/pulldowns enabled
- if peripherals are disabled, pullups and pulldowns need to be disabled as well
Also add comments about the purpose of registers being configured.
This adds a workaround for a bug that following deep sleep wakeup, ISO (bus isolation) signal may be set for RTC fast memory.
We set FORCE_NOISO bit in RTC_CNTL_PWC_REG until we find out what is causing ISO signal to be set.
When ESP32 wakes up from deep sleep, flash is accessed an approximately 900us after power on.
Some flash chips need more time to become ready. This change adds a menuconfig option to add
some delay to the default deep sleep wake stub.
Fixes https://github.com/espressif/esp-idf/issues/117
This adds the following APIs to enable various wakeup sources:
- esp_deep_sleep_enable_timer_wakeup
- esp_deep_sleep_enable_ulp_wakeup
- esp_deep_sleep_enable_ext0_wakeup
- esp_deep_sleep_enable_ext1_wakeup
And an API to start deep sleep:
- esp_deep_sleep_start

Bugfix/btdm bluedroid
Cleanup all the warnings。
Fix GATT CLIENT cannot receive notfiy/indicate from GATT SERVER bug.
Originally, bluetooth have its own master branch(feature/btdm_bluedroid), all the bluetooth sub branch will merge to feature/btdm_bluedroid firstly. If feature/btdm_bluedroid is ready, it will request merge to master. But as Ivan/JG/Jack's requires, all the bluetooth bugfix or feature will request merge to master ASAP.
This MR contains "cleanup warning " and "some bug fix", after, every merge request only contain one thing.

“Full” printf uses more stack space than “nano” printf, and more space than available in the idle task.
This caused stack overflow in TLS delete test. Replacing printf with ets_printf.
add supported stress test to CI
add supported stress test to CI:
stress test requires long time to execute. They will only be executed when variable NIGHT_BUILD=YES. Therefore we'll use gitlab-API trigger to execute stress test cases.
See merge request !220
drivers: remove file paths from log statements
Function name and error string are usually sufficient to find the place which has triggered an error.
`__FILE__` macro generates a string which has absolute file name (with our build system), which add many long strings to the program binary.
Also change log tags to lower case to match style used elsewhere.

Flash encryption support
Flash encryption support in build system, tooling
To come in future MR:
* On-device key generation on first boot (for production devices), need to finalise testing of bootloader entropy seeding.
* spi_flash_encrypted_write to support non-32-byte block writes (at least optionally.)
* I think a lot of the bootloader_support component can possibly be rolled into "spiflash" and other components, to use a common API.
See merge request !240
Add dynamic interrupt allocation mechanism
This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt.
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.
Also:
- Modifies driver to be in line with these changes

newlib: add "full" formatting support
This change adds support for 64-bit formats and C99 features to newlib printf/scanf functions. This support is enabled by default in menuconfig, but can be switched off to reduce code size.
Also adds missing functions such as fmod and fmodf.
- Fixes https://github.com/espressif/esp-idf/issues/52
- Fixes https://github.com/espressif/esp-idf/issues/83
See merge request !274
- add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM.
- fix linker error for fmod, fmodf, atof, atoff
- update tests
UART console selection
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Ref. TW8146
Also includes the following changes:
- `uart_tx_wait_idle`: fix issue with last character not transmitted. ROM function `uart_tx_wait_idle` may have a bug which causes the function to return before the final character is fully transmitted. This replaces `uart_tx_wait_idle` declaration with a static inline definition which fixes the issue. Also replaces the use of `uart_tx_flush` with `uart_tx_wait_idle` in `esp_restart`, to remove garbage in console output on restart.
- `rtc_printf` is temporary replaced with a no-op, pending a new release of librtc.a. Current release assumes that UART0 is used for output,
and switches UART0 baud rate while doing frequency changes and printing some log output. This doesn’t work if a different UART is used for output.
- disable boot watchdog only after starting the main task. Boot watchdogs were disabled very early in startup code. It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name. This change is not directly related to the previous ones, but was found while debugging UART selection features.

Removal of spurious newline character in debug statement
There was a debug statement in the code that included an additional newline character that wasn't needed.

On Xtensa windowed ABI backtrace is easy to do, and it's immensely
useful for debugging, so - do it by default.
We try to be careful and not deref bogus pointers while walking the
frames.
Example output (from debugging espressif/esp-idf#133):
Backtrace: 0x1:0x3ffc51e0 0x400e9dfa:0x3ffc5210 0x400e9ebc:0x3ffc5230 0x400ec487:0x3ffc5260
With just addr2line utility from binutils, this already pinpoints the
location of the crash.

It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name.

Setting happens in bootloader startup code for PRO CPU, and in application startup code for APP CPU.

bugfix(gpio):gpio32 and gpio33 can not output and input
the gpio32 and gpio33 is initialize by librtc.a,and gpio_config not initialize the gpio as
digital gpio.they can not output and input,when users use gpio32 or gpio33.And there are some problems
about others driver ,when they use gpio32 or gpio33 as matrix.
Function name and error string are usually sufficient to find the place which has triggered an error. __FILE__ macro generates a string which has absolute file name (with our build system), so there is a lot of long strings present in the program because of that.

Feature/btdm bluedroid
This branch contain the bluedroid host code.
Currently, Only GAP/GATT SERVER/GATT CLIENT release to users.
Actually, the content of the codes is further more than GAP/GATT and etc.
In this release version, users only need to concern about the APIs which are in "api/include/".
Now, suggestions in comment have been resolved are following:
1. The APIs use callback function. Ivan , Jeroen and me have discussed it. Currently the code will not be changed.
2. The APIs use OPEN/CLOSE. I have ask Ivan, besides bluedroid do this, we will keep the name.
3. Coding style. I have run format.sh to handle the style. And some spell error have been fixed.
4. APIs doxygen. I have clean the warning by doxygen. But bt.rst is still need to be completed.
5. Other comment without resolved face to face that I have to add response in the comment and fix them in the code
6. Fix some incorrect things. See the git log for details.
This 1st version of bluedroid release still have lots of things to do. But it can be done after this merge.
1. Compelete the BLUFI(Bluetooth config wifi connection) documents, security, application protocol and other.
2. Add SPP-LIKE profile.
3. Do more examples codes to cover most of the APIs.
4. Test and fix bug.
Another thing：
1. Do the document of APIs.(xml->bt.rst->html)
(I will do this before merge as Ivan's suggestion)
This is already done. Besides, the union type in doxygen have something error. Ivan will fix it.

lwip: fix socket memory leak issue
1. Add socket memory leak debug counter
2. Fix TCP PCB leak issue
Currently ESP32 support maximum 16 TCP PCBs and all TCP PCB are allocated from heap memory. In some scenario, we may
have memory leak issue, for example, the application already created 16 TCP PCB, then it close 5 of them, because the TCP
state machine, the LWIP core may not free all the 5 TCP PCB immediately, maybe some is in TIME_WAIT status, some is in
FIN_WAIT_1 etc. Then the application try to malloc 17th TCP PCB (the application think they just create 12 because they already
close 5), memp_malloc() will return true because the heap is not out of memory, but actually we got 17 TCP PCB. When the
scenario repeat again and again (in our Audio application, it repeat more than 10000 times), more and more TCP PCB will be
created in the system, each TCP PCB require 200B, then memory leak happen (In Audio application, I saw more than 26 TCP PCB
are created, and 10*200=2K memory are leaked).

ledc: fix reported error when div_param == 256
Whenever bit_num and freq_hz are such that div_param == 256, the code would flag that as an error.
In fact, value 256 of div_param was a valid one (HW requires that div_param >= 1.0, when interpreted as a Q10.8 fixed point value).
Changed the if statements a bit to make the logic clearer, and added more descriptive error messages.
Also added missing error for the unimplemented case of low speed mode.

system_* APIs cleanup
This changeset is mostly about cleaning up `system_*` APIs and moving them from libcore. It has dragged a few more changes along, however.
- `system_deep_sleep` deprecated, new name is `esp_deep_sleep`
- `system_efuse_read_mac` deprecated, new name is `esp_efuse_read_mac`
- `system_read/write_rtc_mem` removed (reason: we use linker to place code/data into RTC memory now)
- `system_get_sdk_version` deprecated. Returns "master" for now. Support for compile-time and runtime version detection will be done in a separate MR.
- `system_get_time` and variations have been deprecated. `gettimeofday` should be used instead.
- `system_restart` deprecated, new name is `esp_restart`. Rewritten code to work correctly from any of the cores.
- `system_restore` deprecated, `esp_wifi_restore` should be used instead.
- `system_get_rst_info` removed (it wasn't in a header file)
- RTC library has been updated to latest version
- Logging output from `libfoo.a` goes through `foo_printf` function now, where `foo ` is any of the library names. For libraries other than rtc and phy, this is a temporary measure, until we finish switching to esp_log library and clean up all uses of printf/ets_printf.
- ESP-IDF build will fail if any of the libraries have printf/ets_printf reference.
- Added `esp_random` function which gets values from HW RNG. I have added code which makes sure the value is not polled too often (allows at least 16 APB cycles). Also added a header file for HW RNG (just one register).
- Moved random number generation functions used by wpa library into wpa_supplicant component.
