XZ_EXTERN was used to make internal functions static in the preboot code.
However, in other decompressors this hasn't been done. On x86-64, this
makes no difference to the kernel image size.
Omit XZ_EXTERN and let some of the internal functions be extern in the
preboot code. Omitting XZ_EXTERN from include/linux/xz.h fixes warnings
in "make htmldocs" and makes the intradocument links to xz_dec functions
work in Documentation/staging/xz.rst. The alternative would have been to
add "XZ_EXTERN" to c_id_attributes in Documentation/conf.py but omitting
XZ_EXTERN seemed cleaner.

Add SPDX license identifier.
Omit xz_dec_test info. That isn't relevant to developers of non-XZ code.
Revise the docs about xzkern and add xzkern_with_size. The latter was
added to scripts/Makefile.lib in the commit 7ce7e984ab ("kbuild: rename
cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}").
Omit contact info as MAINTAINERS has it.
Omit other info that is outdated or not relevant in the kernel context.
Include the xz_dec kernel-doc from include/linux/xz.h.

There are several files that I was unable to find a proper place
for them, and 3 ones that are still in plain old text format.
Let's place those stuff behind the carpet, as we'd like to keep the
root directory clean.
We can later discuss and move those into better places.
