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).

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().

by making a full initialization

14c71dfa9c modified LZ4_initStreamHC() to look like LZ4_initStream() 
it is now a pure initializer, for statically allocated states.
It can initialize any memory area, and because of this, requires size.

2ece0d8380 created LZ4_initStream() 
- promoted LZ4_resetStream_fast() to stable
- moved LZ4_resetStream() into deprecate, but without triggering a compiler warning
- update all sources to no longer rely on LZ4_resetStream()

note : LZ4_initStream() proposal is slightly different :
it's able to initialize any buffer, provided that it's large enough.
To this end, it accepts a void*, and returns an LZ4_stream_t*.

c491df54ec created LZ4_initStreamHC() 
- promoted LZ4_resetStreamHC_fast() to stable
- moved LZ4_resetStreamHC() to deprecated (but do not generate a warning yet)
- Updated doc, to highlight difference between init and reset
- switched all invocations of LZ4_resetStreamHC() onto LZ4_initStreamHC()
- misc: ensure `make all` also builds /tests

the test fails, as intended,
since #631 is not merged yet in this branch.

ce4e1389cc fuzzer.c: enabled ring buffer tests for decompress_fast 
Ring buffer tests were performed only with LZ4_decompress_safe_continue,
leaving my buggy changes to LZ4_decompress_safe_continue undetected.
The tests are now replicated and performed in a similar manner for both
LZ4_decompress_safe_continue and LZ4_decompress_safe_continue (except
for the small buffer case where only one function can be tested,
because part of the dictionary is overwritten with the output).

I also updated function names in the messages (changed them to the
actual ones).  The error was reported for LZ4_decompress_safe(),
which I found misleading.
