ringbuf: Fix bug where comparision between a signed and unsigned operand resulted in incorrect free size for no-split/allow-split buffers (v4.1)
See merge request espressif/esp-idf!15884
This commit fixes a bug in no-split and allow-split ring buffers free buffer size calculation.
When the free size available in the buffers less than the size of one item header,
the function prvGetCurMaxSizeNoSplit/AllowSplit() incorrectly returned the maxItemSize instead of 0.
This is due to the comparision between a negative and a positive value
where both operands are treated as unsigned during the comparision operation,
thereby treating the negative operand as a large integer.
Also added new unit tests to test buffer-full and almost-full conditions
where this scenario is likely to be hit.

4.It is abnormal when getting the deep sleep state bit. So we need to
check the state again and run the "ble_master_soft_rst()" if neesed.
For the CID10564,10384,10280,10098,10038,The memory was released in other place.
For the CID10365,it release the memory in the function when sent successfully.
For the CID10268,10011, we need not change the code.
The release of the semaphore indicating the item was successfully sent must be the last semaphore released. The receiver may be in another task and may delete the Ringbuffer (such as with a return code across tasks design pattern) if they are through with the Ringbuffer.
The function xRingbufferSendAcquire followed by xRingbufferSendComplete had the semaphores released in the proper order and that same pattern should have been used in xRingbufferSend and xRingbufferSendFromISR. This commit fixes this order.
