* All licenses are now standardized
The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.
The copyright and license of `divsufsort.{h,c}` is not changed.
Bugs:
* `ZSTD_DCtx_refPrefix()` didn't clear the dictionary after the first
use. Fix and add a test case.
* `ZSTD_DCtx_reset()` always cleared the dictionary. Fix and add a test
case.
* After calling `ZSTD_resetDStream()` you could no longer load a
dictionary, since the stage was set to `zdss_loadHeader`. Fix and add
a test case.
Cleanup:
* Make `ZSTD_initDStream*()` and `ZSTD_resetDStream()` wrap the new
advanced API, and add test cases.
* Document the equivalent of these functions in the advanced API and
document the unstable functions as deprecated.
isolate all logic associated with block decompression
into its own module.
zstd_decompress is still in charge
of context creation/destruction,
frames, headers, streaming, special blocks, etc.
Compressed blocks themselves are now handled within zstd_decompress_block .
