4ccac94816 freertos: modify configASSERTs around scheduler state check
Regression introduced in commit 79e74e5d5f

It is possible that some FreeRTOS APIs are invoked prior to
scheduler start condition (e.g. flash initialization in unicore mode).
In that condition these asserts should not trigger (scheduler state being yet to be started),
hence changes per this fix.

79e74e5d5f freertos: Fix configASSERT thread safety
This commit fixes thread safety issues with configASSERT() calls
regarding the value of uxSchedulerSuspended. A false negative
occurs if a context switch to the opposite core occurs in between
the getting the core ID and the assesment.

4987a5ad90 fix bug that semaphore may schedule out in Critical Section
1. Since BLE full-scan feature for BLE mesh change the controller code cause this problem,
it cause coex semaphore take in "interrupt disable", then it may cause task schedule
and cause crash in freertos
2. Fix newlib lock ISR context and critical section check
3. Fix bt controller ISR context and critical section check

037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

3882e48e8a cmake: use new signature form of target_link_library to link components
!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.

The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079

562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h

b7841ec313 freertos: use xTaskQueueMutex to protect tick count
Having two different spinlocks is problematic due to possibly
different order in which the locks will be taken. Changing the order
would require significant restructuring of kernel code which is
undesirable.

An additional place where taking xTickCountMutex was needed was in
vApplicationSleep function. Not taking xTickCountMutex resulted in
other CPU sometimes possibly advancing tick count while light sleep
entry/exit was happening. Taking xTickCountMutex in addition to
xTaskQueueMutex has shown a problem that in different code paths,
these two spinlocks could be taken in different order, leading to
(unlikely, but possible) deadlocks.

21ccecc802 freertos: Add critical sections to queue sets.
Queue sets are not SMP safe. This commit adds
critical sections to queue sets. Unit tests for
queue sets have also been added.

4bfa30967f freeRTOS/Re-factor ring buffers
This fixes multiple bugs with ring buffers and re-factors the code. The public
API has not changed, however the underlying implementation have various private
functions have been changed. The following behavioral changes have been made

-   Size of ring buffers for No-Split/Allow-Split buffers will not be rounded
    up to the nearest 32-bit aligned size. This was done to simplify the
    implementation

-   Item size for No-Split/Allow-Split buffers will also be rounded up to the
    nearest 32-bit aligned size.

The following bugs have been fixed

-   In copyItemToRingbufAllowSplit(), when copying an item where the aligned
    size is smaller than the remaining length, the function does not consider
    the case where the true size of the item is less than 4 bytes.

-   The copy functions will automatically wrap around the write pointers when
    the remaining length of the buffer is not large enough to fit a header, but
    does not consider if wrapping around will cause an overlap with the read
    pointer. This will make a full buffer be mistaken for an empty buffer

closes #1711
-   xRingbufferSend() can get stuck in a infinite loop when the size of the
    free memory is larger than the needed_size, but too small to fit in the ring
    buffer due to alignment and extra overhead of wrapping around.

closes #1846
-   Fixed documentation with ring buffer queue set API

-   Adding and removing from queue set does not consider the case where the
    read/write semaphores actually hold a value.

The following functions have been deprecated
    - xRingbufferIsNextItemWrapped() due to lack of thread safety
    - xRingbufferAddToQueueSetWrite() and xRingbufferRemoveFromQueueSetWrite()
    as adding the queue sets only work under receive operations.

The following functions have been added
    - xRingbufferReceiveSplit() and xRingbufferReceiveSplitFromISR() as a thread
    safe way to receive from allow-split buffers
    - vRingbufferGetInfo()

Documentation for ring buffers has also been added.

32e838ddb6 Add xRingbufferCanRead, xRingbufferCanWrite
Add function xRingbufferCanRead & xRingbufferCanWrite
to be able use queue sets. Without it is not possible
to check to which ringbuffer returned semaphore belongs.
