Yann Collet b8d4a3887f introduced constant ZSTD_frameIdSize 
within zstd_internal.h
This is the size of magic number.

Avoids using `4` directly in source code, which is a bit less meaningful.
 2017-09-25 15:26:18 -07:00
Yann Collet 044fb4c057 implemented magic-less frame decoder 2017-09-25 15:12:09 -07:00
Yann Collet 62568c9a42 added capability to generate magic-less frames 
decoder not implemented yet

Yann Collet 96f0cde31a minor function rename 
ZSTD_estimateCStreamSize_advanced_usingCParams -> ZSTD_estimateCStreamSize_usingCParams
_usingX is clear.
_advanced feels redundant
