streaming decoders, such as ZSTD_decompressStream() or ZSTD_decompress_generic(),

(aka no byte read from input __and__ no byte written to output),

In such case, the caller may be caught in an infinite loop,
calling the streaming decompression function again and again,
without making any progress.

This version detects such situation, and generates an error instead :
ZSTD_error_dstSize_tooSmall when output buffer is full,
ZSTD_error_srcSize_wrong when input buffer is empty.

The detection tolerates a number of attempts before triggering an error,
controlled by ZSTD_NO_FORWARD_PROGRESS_MAX macro constant,
which is set to 16 by default, and can be re-defined at compilation time.
This behavior tolerates potentially existing implementations
where such cases happen sporadically, like once or twice,
which is not dangerous (only infinite loops are),
without generating an error, hence without breaking these implementations.
