first draft of zstd debug sections support
Made first draft of Zstandard-compressed debug sections support. Patch looks
huge but most of the data is code of "zstddeclib.c", single-file version of
zstd decompressor made with their tool as described here:
https://github.com/facebook/zstd/blob/dev/build/single_file_libs/README.md . I
used source from 1.5.6 version, latest stable at this time.
After generation, it was manually fixed to use VG_(malloc), VG_(calloc) and
other such functions, basically until it compiled.
Aside from that, I used final attachment from
https://bugs.kde.org/show_bug.cgi?id=303877 as a template. Except for NEWS,
don't really know where should I add it and if I should be the one to add.
Changes are quite trivial:
* `UChar typeC; // type of compressed data` was added to struct CSlc
* In `ML_(img_mark_compressed_part)` new argument was added, `UChar typeC`
* In `check_compression`, type of compression now provided to
`img_mark_compressed_part`
* in `get_slowcase` now either `ZSTD_decompress` or
`tinfl_decompress_mem_to_mem` depending on cslc->typeC
* Tests were added to check if Zstd decompression is working.
That's it basically it.
I should say thanks to Aleksandar Rikalo for making code that can be easily
adapted for new compression types and to Sam James for providing useful links.
I do have a problem with compiling any of the tests, be it for ZLIB or ZSTD,
but manual test building and checking works fine. How to build said tests, BTW?
