extend deep sleep APIs
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
Add an API to control which peripherals are kept enabled in deep sleep mode:
- esp_err_t esp_deep_sleep_pd_config
Also rolled an update of rtc_io header comments into this MR, as I had to add `slpie`, `slpsel`, and `hold` fields into `rtc_gpio_desc_t` struct.
Deep sleep unit tests don’t do anything useful in CI context because we don’t have a way to check reset behavior (time till reset, reason for reset) in CI environment, yet. Also for external wakeup we would need to control some ESP32 pins from the test environment.
Currently there is one known issue:
- RTC Fast memory may be isolated from the bus after deep sleep reset. We work around this by setting FORCE_NONISO flag in RTC power control register. This is non-optimal and we will keep looking for the reason why isolation gets enabled.
See merge request !297
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.

1. TW8657, WIFI send the whole packet to smartconfig;
2. modify API annotation of smartconfig and sniffer;
3. export smartconfig APIs to programming guide;

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.

Update uart examples in uart.h to new interrupt allocation scheme
Some of the examples in the UART header haven't been adjusted to the new interrupt scheme; this fixes that. Also runs dos2unix on the drivers tree; a fair few drivers used DOS-style line ends.

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.
Create temp config in the same dir as target
Fixes case where SDK and app are on different mounts
(In our usage of kconfig, dirname is the empty string & basename is the full path to sdkconfig)

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
Fix broken WiFi due to intr allocation code.
TL;DR: The dynamic interrupt allocation code fixed something up to the point it broke. This code breaks off the broken code, fixing everything.
The dynamic allocated interrupt patch also fixed a bug in FreeRTOSs interrupt handling for two cores, which caused the two cores to (most of the time) have exactly the same interrupts enabled. This made WiFi fail: it would wait on a semaphore but never figure out the other core had set the semaphore, so it would keep waiting in the idle task for ever. This was caused by both the cross-core interrupt as well as the tick interrupt being disabled.
The culplrit for this appeared to be the WiFi driver, which enabled a FRC2 interrupt. The code enabling this, through a respectable amount of defines, called a rom function which called a HAL function... which was configured in such a way that it worked okay if both CPUs happened to have the same interrupts set, but broke as soon as that was not the case, possibly setting only the interrupt that was enabled and clearing all others.
The fix for this is to not use the ROM functions, but provide our own instead. Fortunately, this can be done without changes in the WiFi libs.
This MR also addresses a potentially dangerous ESP_LOG as well as some, according to the ISA document, needed rsyncs in the interrupt enable/disable code. It also marks int 9 and 10 as reserved, the WiFi code seems to use this.
