e0065cf660 make test : removed zstreamtest unit tests for variants 
slightly reduced time to create dictionary

47c6a95d07 zstreamtest : run unit tests only during "normal" session 
not during --mt, --newapi and --opaque
this avoids running them 4x during `make test`

86b4fe5b45 adjustCParams : restored previous behavior 
unknowns srcSize presumed small if there is a dictionary (dictSize>0)
and presumed large otherwise.

9fe50ed623 fixed maximum windowLog for zstreamtest --newapi

9b5b47ac93 ensure adjustCParams adjust hLog and cLog even without srcSize 
It would previously exit when srcSize is unknown.
But in the case of custom parameters,
hLog and cLog can still be too large in comparison with windowLog.

Reduces maximum memory allocated during zstreamtest --newapi

Change c++ test to use CXX and CXXFLAGS environment variables

ea1f50bf73 removed ZSTD_decompressBegin() from ZSTD_initDCtx_internal() 
It does not feel "right" from a dependency perspective.
ZSTD_initDCtx_internal() is triggered once, on DCtx creation,
while ZSTD_decompressBegin() is invoked at the beginning of each new frame,
and is also a user-facing prototype.

Downside : a DCtx must be init before first usage !
This was always the intention by the way, and is documented as such.
This stage is automatically done within ZSTD_decompress() and variants,
and also within ZSTD_decompressStream().
Only ZSTD_decompressContinue() is impacted,
it must be preceded by a ZSTD_decompressBegin(), as detailed in doc.

A test has been fixed, to no longer rely on undocumented assumption that ZSTD_decompressBegin() is invoked during init.

ca306c1c84 fixed a bug in zstreamtest 
decoder output buffer would receive a wrong size.

In previous version, ZSTD_decompressStream() would blindly trust the caller that pos <= size.
In this version, this condition is actively checked,
and the function returns an error code if this condition is not respected.

This check could also be done with an assert(),
but since this is a user-facing interface, it seems better to keep this check at runtime.

471aa385b3 [fuzz] Speed up round trip tests 
* Enforce smaller maximum values for parameters
* Adjust parameters to the source size

The memory usage is reduced by about 5x, which makes the fuzzers run at
least twice as fast, even more so with ASAN/MSAN enabled.
