Michael TokarevandAlex Bennée 9e8be4c546 drop libxml2 checks since libxml is not actually used (for parallels) 
For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.

It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.

Drop all mentions of libxml2.

[*] Actually the basis for libxml use were introduced in commit
    ed279a06c5 ("configure: add dependency") but the implementation
    was never merged:

Thomas Huth 7b59d10e23 scripts/checkpatch: Improve the check for authors mangled by the mailing list 
There were recently some patches on the list which had their "From:"
line mangled like this:

 From: qemu_oss--- via <qemu-devel@nongnu.org>

Since our test in the checkpatch.pl script did not trigger here, the
patches finally also ended up in a pull request, with the wrong author
set. So let's improve the regular expression to also complain on
these new patterns, too.

Dov MurikandPaolo Bonzini bfac6d1933 checkpatch: Detect '%#' or '%0#' in printf-style format strings 
According to the coding style document, we should use literal '0x' prefix
instead of printf's '#' flag (which appears as '%#' or '%0#' in the format
string).  Add a checkpatch rule to enforce that.

Note that checkpatch already had a similar rule for trace-events files.

Example usage:

  $ scripts/checkpatch.pl --file chardev/baum.c
  ...
  ERROR: Don't use '#' flag of printf format ('%#') in format strings, use '0x' prefix instead
  #366: FILE: chardev/baum.c:366:
