25d96f1e4d fix out-of-bound read within LZ4_decompress_fast() 
and deprecate LZ4_decompress_fast(),
with deprecation warnings enabled by default.

Note that, as a consequence of the fix,
LZ4_decompress_fast is now __slower__ than LZ4_decompress_safe().
That's because, since it doesn't know the input buffer size,
it must progress more cautiously into the input buffer
to ensure to out-of-bound read.

ce0f316989 fix fuzzer tests on dirty context 
context is no longer dirty after a failed compressed block.
Actually, all indexes are fine.
It remains compatible with continued streaming, and reset*_fast().

474c17cdc4 unified limitedOutput_directive 
between lz4.c and lz4hc.c .
was left in a strange state after the "amalgamation" patch.

Now only 3 directives remain,
same name across both implementations,
single definition place.

Might allow some light simplification due to reduced nb of states possible.

1f4a412646 decompress*_fast() function do not generate deprecation warnings 
they are classified as deprecated in the API documentation (lz4.h)
but do not yet trigger a warning,
to give time to existing applications to move away.

Also, the _fast() variants are still ~5% faster than the _safe() ones
after Dave's patch.

481a37fe47 fixed lz4frame with linked blocks 
when one block was not compressible,
it would tag the context as `dirty`,
resulting in compression automatically bailing out of all future blocks,
making the rest of the frame uncompressible.

dd43b913a2 fix minor visual warning 
yet some overly cautious overflow risk flag,
while it's actually impossible, due to previous test just one line above.
Changing the cast position, just to be please the thing.

f8b7605034 fixed minor Visual warnings 
since Visual 2017,
worries about potential overflow, which are actually impossible.
Replaced (c * a) by (c ? a : 0).
Will likely replaced a * by a cmov.
Probably harmless for performance.

20c2a5fc94 added command -BI for "Independent Blocks" 
This is the reverse of `-BD`, and the current default.

This command can be useful to reverse a previous `-BD` command.
It may in the future be more important
if `lz4` switches to generating dependent blocks by default.
