still fighting data corruption
...
due to messed up tree.
Seems to happen when reaching end of buffer.

merged repcode search into BT match search
...
this version has same speed as branch `opt`
which is itself 5-10% slower than branch `dev`
(no identified reason)
It does not compress exactly the same as `opt` or `dev`,
maybe because it doesn't stop search after repcodes,
leading to sometimes better compression, sometimes worse
(by a small margin).
warning : _extDict path does not work for the time being
This means that benchmark module works,
but file module will fail with large files (and high compression level).
Objective is to fuse _extDict path into current one,
in order to have a single parser to maintain.

lib/compress: created ZSTD_LLcode() and ZSTD_MLcode()
...
transform length into code.
Since transformation is needed in several places throughout the code,
better write the logic in one place.

zstd_opt: simplified ZSTD_getPrice() and ZSTD_updatePrice() interface
...
ZSTD_getPrice() and ZSTD_updatePrice() accept normal matchlength as argument
instead of matchlength-MINMATCH,
which makes them easier / more logical to use and read.
Conversion is simply done internally.
