liblzma: Add .lz (lzip) decompression support (format versions 0 and 1).
Support for format version 0 was removed from lzip 1.18 for some
reason. .lz format version 0 files are rare (and old) but some
source packages were released in this format, and some people might
have personal files in this format too. It's very little extra code
to support it along side format version 1 so this commits adds
support for both.
The Sync Flush marker extentension to the original .lz format
version 1 isn't supported. It would require changes to the
LZMA decoder itself. Such files are very rare anyway.
See the API doc for lzma_lzip_decoder() for more details about
the .lz format support.
Thanks to Michał Górny for the original patch.
