Sudeep Mohanty 9e46667545 ringbuf: Fix bug where comparision between a signed and unsigned operand resulted in incorrect free size for no-split/allow-split buffers ... 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.
