esp32: Bootloader wake deep sleep stub
App can contain a stub program resident in RTC fast memory. Bootloader
will load the stub on initial boot. If the device wakes from deep sleep,
the stub is run immediately (before any other data is loaded, etc.)
To implement a custom wake stub, implement a function in your program:
```
void RTC_IRAM_ATTR esp_wake_deep_sleep(void)
{
esp_default_wake_deep_sleep();
// other wake logic
}
```
... and it will replace the default implementation.
See merge request !78
We reserve 4KB Slow RTC memory to save RF calibation result and BT NVS data.
If not all these Slow RTC momory Blocks are used, we will open the other parts.
Workaround: Automatically pin no-cpu-affinity task to a core when FPU is used
FPU status at the moment does not migrate cleanly between cores, so tasks without affinity that happen to migrate across FPUs will run into problems. As a workaround, this modification will automatically pin the task to the current CPU when FPU activity is detected. If anything, it's better than getting all kinds of weird and wonderful FPU corruption issues...

Assert on untested FreeRTOS features
When I SMP-enabled, I went through all the functions and made the necessary modifiucations. I however only managed to test the most used functions thoroughly. While we should test all FreeRTOS functions eventually, this MR will mark the ones we have not tested yet with a macro call that will, if enabled in MenuConfig (default enabled) assert() when the untested function is called.
Also removes some superfluous mux initializion code in EventGroups code.

1. configure LEDC timer saparately
2. add peripher_crtl.c/.h
To enable the peripheral modules, we have to set/clear the control register in dport_reg.h.
These bits are disabled by default and they are all in a same register, so we need to add a lock on that.
3. add include esp_err.h in gpio.h
component/bt: update libbtdm_app.a
1. update the lib to version 010102 because the branch feature/btdm_controller missed the lib

...
While this may reduce esp_wifi.h file readability for people who don't have a "go to definition" function in their editors, this is needed to decouple esp_wifi and esp_event headers, and possibly other headers which may use wifi types in the future.
Startup flow refactoring
This set of commits changes the startup code in a way that lets the application choose if/when to initialize WiFi/BT.
Application entry point is now a more familiar `main()` function. This function is executed in its own task. Application may choose to do some initialization from main function, create some tasks and then return from `main`. Simple applications may choose to do all their work from `main`.
Additionally this MR splits event handling code into two parts.
- One part is a set of standard handlers for WiFi and DHCP events. Most applications will use this set of handlers, and it is made available via new `esp_event_process_default` function.
- Another part is the default implementation of event handling loop. Some applications may choose to use default event loop through `esp_event_loop_` set of APIs, which start an event handling task and call user-provided event callback from this task. Other applications may create an event queue and implement event loop themselves. In this case application has to provide `esp_event_send` function. In this case the implementation provided by `esp_event_loop_` module is unused.
esp-idf-template has been updated to match this set of changes: https://github.com/espressif/esp-idf-template/tree/feature/init_refactoring
BT example has also been updated.
We need to provide examples of both event handling approaches. This will be done in a separate follow-up MR.

nvs: speed improvement and erase APIs
NVS initialization speed issue raised in https://ezredmine.espressif.com/issues/6881 has been addressed for single core mode through optimization of `spi_flash_*` routines. This MR addresses same issue for dual core mode.
- An index table is added at Page level, it allows doing fast search of item index based on key name and namespace. This heavily reduces the number of flash reads.
- Write operations are batched when writing/erasing long variable-length values (str and blob). This gives a 33% reduction in the number of writes for a 64-byte value, 50% reduction for a 96-byte value.
- Add optional (configurable via menuconfig) perfomance counters for spi_flash APIs
With these changes, total init time for NVS goes down from 2 seconds to 140 ms.
Additional RAM usage is 128-640 bytes per page, depending on content. Typical RAM usage for current use case (storing wifi configuration parameters) is 256 bytes.
This change also exposes APIs to erase single key or the whole namespaces, needed for https://ezredmine.espressif.com/issues/6769.

Clean up warnings and remove unused parts of FreeRTOS
For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Additionally prvLockQueue/prvUnlockQueue have been removed, dragging some other bits of FreeRTOS along.
Original issue: https://github.com/espressif/esp-idf/issues/18
See merge request !111
- put contents of a few headers into c++ guard blocks
- fix off-by-one error in do_global_ctors
- remove system_init from startup code (should be called from main)
This change separates definitions in esp_event.h and functions in event.c into several parts:
- event structure definitions (esp_event.h)
- default implementations of event handlers (event_default_handlers.c)
- default implementation of event loop (event_loop.c, esp_event_loop.h)
Purpose of this change is to allow applications choose their own poison:
- full control of event loop at the expense of more bootstrap code
- pre-defined event task firing event callbacks, but less code in app_main.c
For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Only remaining warning is in FreeRTOS queue.c, and it may be a useful one.
This change removes implicit WiFi/BT initialization from startup code.
"main" task is started once essential part of startup code is complete.
This task calls application-provided "int main(void)" function, which can call WiFi/BT init functions if necessary.
For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Only remaining warning is in FreeRTOS queue.c, and it may be a useful one.
Introduces new internal function, Page::alterEntryRangeState, which gathers changes to multiple elements of entry state table into a single write, provided that these changes fall into a single word. This allows changing state of up to 16 entries in a single write.
Also adds new function, writeEntryData, which writes the whole payload of SZ and BLOB type entries in one go, instead of splitting it into multiple 32-byte writes.
This reduces number of writes required for SZ and BLOB entries.
This feature allows to use static buffers (or from a pool of memory which is not
controlled by FreeRTOS).
In order to reduce the impact of the changes, the static feature has only been added
to the queus (and in consequence to the semaphores and the mutexes) and the tasks.
The Timer task is always dynamically allocated and also the idle task(s), which in the
case of the ESP-IDF is ok, since we always need to have dynamic allocation enabled.

peripheral structure headers: move volatile keyword from members to typedef
Adding -fstrict-volatile-bitfields to the CFLAGS/CXXFLAGS. Without this, gcc tries to access bitfields using the smallest possible methods (eg l8i to grab an 8-bit field from a 32-bit). Our hardware does not like that. This flag tells gcc that if a bitfield is volatile, it should always use the type the field is defined at (uint32_t in our case) to size its access to the field. This fixes accessing the hardware through the xxx_struct.h headers.

Add logging library
Logging library, intended to be used across other components.
Uses design similar to Android NDK logging APIs and allows for both compile time and run time filters, similar to logcat.
Also includes cleanup of cpu_startup.c — i was changing some logging output in this file so decided to re-format it and reduce code duplication.

Enable SO_REUSEADDR in LWIP
Daniel initially asked me why this wasn't enabled, and I don't think I got any reasons against enabling this. If any, it makes porting existing software easier. Tuan needs it for UDP multicast as well.
Code changes are by Tuan: basically the enable for SO_REUSEADDR in LWIP as well as a bugfix in a bit of mbedTLS that gets enabled.

Move CPU region protection setup into soc/cpu.h
change tabs to spaces

This also removes logging implementation from bootloader and replaces it
with the one provided by the log component. Some occurrences of printf
and ets_printf have been changed to ESP_LOGx APIs.
Note that with WiFi stack enabled, system_init will reset frequency to 240MHz.
To make this setting useful, esp32-wifi-libs submodule needs to be updated.

3. esp_wifi_tx_enable return whether tx_enable is true
4. If esp_wifi_tx_enable return false, socket will be blocked

This fixes the performance impact for spi_flash_write and spi_flash_erase.
With this change, NVS init in single core mode takes about 50ms (compared to >2seconds before that).
Dual core compatible spi flash APIs
Implementation of spi flash APIs which work in dual core mode.
This also includes other changes:
- fixes to FreeRTOS tasks.c made by Jeroen and me — these were originally made to fix issues with high priority tasks seen in WiFi stack, but were required to get stuff in ipc.c working as well
- initial base idea with two high-priority tasks was separated into a separate API — esp_ipc.h. That API allows one to run a function on the other CPU from a high-priority task. Because we don't have preemption across CPUs, this is currently not very fast: it requires on average half a tick until the second CPU switches to the high priority task. Currently that API can be either blocking, or non-blocking with queue length of 1. I haven't yet found a use case for arbitrary sized queue of IPC requests. Anyone who needs that can trivially add that later by replacing a binary semaphore with a generic queue.
With these changes i can run application with WiFi stack and NVS on both cores.
