bugfix: uart event mismatch
Fix bug of uart frame error and parity error interrupt mismatch in driver code, which will cause the corresponding interrupt can not be cleared correctly, and will finally cause a interrupt watch dog.

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.

ULP: add new instructions, fix bugs, add tests
This adds peripheral register read and write instructions, an instruction to wake the SoC from deep sleep, and some tests.
Also fixes two bugs: ANDI instruction definition, and running the ULP when in deep sleep mode.
See merge request !317
Fix exception handler to jump to correct vector instead of crashing to the double exception vector.
One-character fix... basically, this caused the exception handler to crash into the double-exception handler instead of nicy panic'ing.

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

Restore ability to alloc IRAM, and more.
- Fix mem regions so allocating IRAM works again
- Optimize allocator slightly, uses 4 less bytes per malloc now
- Allow querying free heap memory space per memory type

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.

1. enable will malloc, but disable don't free resolving list, so fix it
2. In disable procedure, it will alloc alarm to hash_map, and all the alarm hash_map will be free in deinit. So this need not be fixed currently.
build system: Linker scripts or binary libraries should trigger a re-link
Add binary libraries and linker scripts to the list of dependencies for the ELF file.
Fixes TW7816.

Allow interfaces to be configured without a default gateway, for
local-only communication.
In case of the AP interface, if gw is not set, do not offer it.
1. fix the exception of deinit/disable
2. debug mem leak of deinit, fix some memleak, but still something wrong.
3. debug men leak of disable.
4. add bluedroid memory debug
“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
See merge request !254
Fail CI build on warnings

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.
