xz: Use threaded mode by defaut (as if --threads=0 was used).
This hopefully does more good than bad: + It's faster by default. + Only the threaded compressor creates files that can be decompressed in threaded mode. - Compression ratio is worse, usually not too much though. When it matters, -T1 must be used. - Memory usage increases. - Scripts that assume single-threaded mode but don't use -T1 will possibly use too much resources, for example, if they run multiple xz processes in parallel to compress multiple files. - Output from single-threaded and multi-threaded compressors differ but such changes could happen for other reasons too (they just haven't happened since 5.0.0).
