bb5c34a875 bumped version number to v1.9.2 
to reduce risks that future bug reports in `dev` branch report `v1.9.1` as the failing version.

567b4e098b moved noisy-src decoder test into cBuffer_exact 
so that it can also catch any potential read out-of-bound in the input buffer
(none reported so far, just a precaution for the future).

and that such metadata must be provided / sent / saved by the application.

64b5917736 FAST_DEC_LOOP: only did offset check in specific condition. 
When I did FAST_DEC_LOOP performance test, I found the
offset check is much more than v1.8.3

You will see the condition check difference via lzbench with dickens test case.
v1.8.3 34959
v.1.9.x 1055885

After investigate the code, we could see the difference.
v.1.8.3 SKIP the condition check if
if condition is true in:
https://github.com/lz4/lz4/blob/v1.8.3/lib/lz4.c#L1463
AND below condition is true
https://github.com/lz4/lz4/blob/v1.8.3/lib/lz4.c#L1478\
The offset check should be invoked.

v1.9.3
The offset check code will be invoked in every loop which lead to downgrade.
So the fix would be move this check to specific condition
to avoid useless condition check.

After this change, the call number is same as v1.8.3

89c97d5ea6 fullbench: added test scenario LZ4F_decompress_followHint 
This emulates a streaming scenario,
where the caller follows rigorously the srcSize hints
provided as return value of LZ4F_decompress().

This is useful to show the issue in #714,
where data is uselessly copied in a tmp buffer first.
