- Update xz from 5.0 to xz 5.2

xz 5.2 introduces parallel compression.

This update should not break anything because xz is very carefully and compatible
maintained by upstream. I'm using this 5.2 package since years on 13.1 and 42.1
without any problems. The library is even binary compatible.

BTW xz 5.0 already has the --threads option too with no implementation for forward
compatibility.

See the most interesting changes (xz 5.2.0):
* liblzma:
- Added support for multi-threaded compression
- Made the uses of lzma_allocator const correct.
- Added lzma_block_uncomp_encode() to create uncompressed
.xz Blocks using LZMA2 uncompressed chunks.
- Added support for LZMA_IGNORE_CHECK.
- A few speed optimizations were made.
- Added support for symbol versioning. It is enabled by default
on GNU/Linux, other GNU-based systems, and FreeBSD.
* xz:
- Fixed a race condition in the signal handling
- Multi-threaded compression can be enabled with the
--threads (-T) option.
- New command line options in xz: --single-stream,
--block-size=SIZE, --block-list=SIZES,
--flush-timeout=TIMEOUT, and --ignore-check.
- xz -lvv now shows the minimum xz version that is required to
decompress the file. Currently it is 5.0.0 for all supported
.xz files except files with empty LZMA2 streams require 5.0.2.
* xzdiff and xzgrep now support .lzo files if lzop is installed.
The .tzo suffix is also recognized as a shorthand for .tar.lzo.

%description
The xz command is a very powerful program for compressing files.
-
* Average compression ratio of LZMA is about 30% better than that of
gzip, and 15% better than that of bzip2.
-
* Decompression speed is only little slower than that of gzip, being
two to five times faster than bzip2.
-
* In fast mode, compresses faster than bzip2 with a comparable
compression ratio.
-
* Achieving the best compression ratios takes four to even twelve
times longer than with bzip2. However. this doesn't affect
decompressing speed.
-
* Very similar command line interface to what gzip and bzip2 have.

+.SH NAME
+xznew \- recompress .gz or .tgz files to .xz files
+.SH SYNOPSIS
+.B xznew
+[ -ftv9PK] [ name.gz ... ]
+.SH DESCRIPTION
+.I xznew
+recompresses files from .gz (gzip) format to .xz (xz) format.
+If you want to recompress a file already in xz format, rename the file
+to force a .xz extension then apply xznew.
+.SH OPTIONS
+.TP
+.B \-f
+Force recompression from .gz to .xz format even if a .xz file already exists.
+.TP
+.B \-t
+Tests the new files before deleting originals.
+.TP
+.B \-v
+Verbose. Display the name and percentage reduction for each file compressed.
+.TP
+.B \-9
+Use the slowest compression method (optimal compression).
+.TP
+.B \-P
+Use pipes for the conversion to reduce disk space usage.
+.TP
+.B \-K
+Keep a .gz file when it is smaller than the .xz file
+.SH "SEE ALSO"
+xz(1), gzip(1)
+.SH BUGS
+.I xznew
+does not maintain the time stamp with the -P option if
+.I cpmod(1)
+is not available and
+.I touch(1)
+does not support the -r option.
