`xQueueGenericCreateStatic` is placed into flash by the linker script to
reduce IRAM usage. This will also cause the `xRingbufferCreate` not
not callable when cache is disabled.
1. add hal and low-level layer for timer group
2. add callback functions to handle interrupt
3. add timer deinit function
4. add timer spinlock take function
This commit updates does the following:
- xRingbufferCreateStatic() added to allow ringbuffers via to be statically
allocated. Docs and unit tests update accordingly. Closes#3064
- Fix doc typos, closes#3248. Updated API reference regarding to mention
item size limits of no-split buffers when calling
xRingbufferGetCurFreeSize() or xRingbufferGetMaxItemSize(), closes#3117.
- Remove the following deprecated types/functions for v4.0
- xRingbufferIsNextItemWrapped()
- xRingbufferAddToQueueSetWrite()
- xRingbufferRemoveFromQueueSetWrite()
The following 2 compiler warnings are only reproducible when setting:
OPTIMIZATION_FLAGS = -Ofast

New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
In earlier change this component was decoupled from freertos and hence
regression was introduced which changed default placement to flash. Some
device drivers make use of ringbuffer while flash cache is being disabled
and hence default placement should instead be internal memory.
Closes: https://github.com/espressif/esp-idf/issues/2517
