W. Felix Handte 5da9bbc38e Conceivably Dedup ZSTD_noDict and ZSTD_dictMatchState _insertBt1 Impls
By reverting to the bool extDict flag, we call ZSTD_insertBt1 with the same
const args in both non-extDict dictModes.

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.

Grouped debug functions into debug.h

Yann Collet 1adf84ccb7 renamed all HUF_decompress*X4*() functions into *X2
to underline they generate up to 2 symbols per decoding,
in preparation for a future *X3 variant.

Yann Collet a09af5eb6b renamed all HUF_decompress*X2*() functions into *X1
to underline they generate one symbol per decoding operation.

The new naming scheme will make it easier to introduce an *X3 variant.

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it has been replaced by DEBUGLEVEL,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.
