since corrupted bitstreams can generate too large values.
This slightly reduces the benefits from clang on my laptop.
gcc results and code generation are not affected.
while reviewing #1364,
I found a decompression speed improvement.
On my laptop, the new code decompresses +5-6% faster on clang
and +2-3% faster on gcc.
not bad for an accidental optimization...
There were 2 competing set of debug functions
within zstd_internal.h and bitstream.h.
They were mostly duplicate, and required care to avoid messing with each other.
There is now a single implementation, shared by both.
Significant change :
The macro variable ZSTD_DEBUG does no longer exist,
it has been replaced by DEBUGLEVEL,
which required modifying several source files.
* Replaced a non-breaking space and an en dash with a plain space and
a hyphen.
* This means the files are simple ASCII and less likely to run into
codepage issues.
The following warning appears during the build. Fixed the review comments too.
zstd/lib/common/bitstream.h: In function ‘BIT_initDStream’:
zstd/lib/common/bitstream.h:277:33: warning: this statement may fall through [-Wimplicit-fallthrough=]
case 7: bitD->bitContainer += (size_t)(((const BYTE*)(srcBuffer))[6]) <<
(sizeof(bitD->bitContainer)*8 - 16);
