Include a header to get the declaration for xml_builtin. This
avoids a warning from sparse:
CC m68k-softmmu/gdbstub-xml.o
gdbstub-xml.c:244:12: warning: symbol 'xml_builtin' was not declared. Should it be static?

Change checkpatch.pl for QEMU use:
- Root directory detection
- Forbid tabs
- Indent at 4 spaces
- Allow typedefs
- Enforce brace use even for single statement blocks
- Don't suggest nonexistent cleanup tools
Mention the script in CODING_STYLE.
