Yann Collet 166901dc72 reduced POOL_resize() restriction 
It's not necessary to ensure that no job is ongoing.
The pool is only expanded, existing threads are preserved.
In case of error, the only option is to return NULL and terminate the thread pool anyway.

Yann Collet 066fbbfe1c make zstdmt resize its context 
when nbThreads change.

Technically, it only expands.
But when instructed to use less threads,
the thread pool will limit nb of concurrent threads.

Nick Terrell 3841dbac84 Adjust advanced parameters to source size 
In the new advanced API, adjust the parameters even if they are explicitly
set. This mainly applies to the `windowLog`, and accordingly the `hashLog`
and `chainLog`, when the source size is known.

Yann Collet 6901c94cd6 avoid duplicate code comments 
when a function is decribed in hist.h,
do not describe it again in hist.c
to avoid future doc synchronization issues.

W. Felix Handte ace9cfa950 Attach Dicts when Using ZSTD_btlazy2 2018-06-13 16:06:28 -04:00
Yann Collet fa41bcc2c2 grouped debug functions into debug.h 
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it has been replaced by DEBUGLEVEL,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.
