As discussed in the s390 trace thread, this adds target description
in XML format to tfile format.  The idea is simple:

1. target.xml is read from the target.
2. Includes are processed, resulting in a single in-memory XML file
   containing all the data.
3. The resulting file is stored in tfile header by prefixing every line
   with "tdesc ".  We may insert a spurious newline at the end of file
   with this encoding, but that won't matter for XML.
4. When tfile is read, the XML is stored in an allocated buffer, and
   xfer for TARGET_OBJECT_AVAILABLE_FEATURES is implemented, reading
   from it.
5. target_find_description is called to force reading it.

Patch #1 makes tsave write the XML data into tfile.  Patch #2 makes
tfile reader fetch and parse this data.  Patch #3 fixes wrong register
ordering in tfile_fetch_registers (noticed on x86_64 with AVX -
plain x86_64 was apparently fine).  Patch #4 fixes an off-by-one
in the same function that prevented fetching the last register
(orig_rax for plain x86_64, $ymm15h for x86_64 with AVX).
