ZSTD_compress_generic() is renamed ZSTD_compressStream2().
Note that, for the time being,
the "stable" API and advanced one use different parameter planes :
setting parameters using the advanced API does not influence ZSTD_compressStream()
and using ZSTD_initCStream() does not influence parameters for ZSTD_compressStream2().
* 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.
