Lasse Collin bf4d064d89 lib/xz: enable all filters by default in Kconfig
This restores the old behavior that existed before 2013-02-22, when
changes were made by 64dbfb444c ("decompressors: drop dependency on
CONFIG_EXPERT") and 5dc49c75a2 ("decompressors: make the default
XZ_DEC_* config match the selected architecture").

Disabling the filters only makes sense on embedded systems.

LZMA2 compression algorithm and BCJ filters are supported using
the .xz file format as the container. For integrity checking,
CRC32 is supported. See Documentation/xz.txt for more information.

This allows passing .xz files to the in-kernel XZ decoder via
a character special file. It calculates CRC32 of the decompressed
data and writes diagnostics to the system log.
Unless you are developing the XZ decoder, you don't need this
and should say N.
