[libvirt] [PATCH 2/2] maint: update to latest gnulib

[Eric Blake]

* .gnulib: Update to latest, for syntax-check improvement.
* .x-sc_prohibit_empty_lines_at_EOF: Add more exemptions.
---

Inspired by the fact that I just noticed that Michal's patch
to xenxs/xen_xm.c fixed a potential portability problem -
compilers are allowed to reject files that don't end in newline.
Jim Meyering updated the gnulib syntax-check rule to catch
missing newlines at end of file.

* .gnulib 17adb5d...47824c7 (28):
  > maint.mk: detect missing-NL-at-EOF, too
  > dirname: move m4/dos.m4 functionality into lib/dosname.h
  > strstr: revert patches that introduced bug and pessimization
  > filenamecat: remove unnecessary dependency on dirname-lgpl
  > remove: remove unnecessary use of m4/dos.m4
  > * lib/openat-proc.c: Don't include dirname.h; not needed.
  > ChangeLog: credit Mike Stump; add a URL for the thread
  > backupfile: remove unnecessary use of m4/dos.m4
  > strstr: fix a bug whereby strstr would mistakenly return NULL
  > gnulib-tool: remove use of bold display in help screen

  > maint: sc_cpp_indent_check: remove the "only in lib/" restriction
  > maint: avoid any CDPATH issue
  > maint: adjust cpp indentation for my modules, as well
  > maint: adjust cpp indentation to reflect nesting depth
  > New module 'wctomb'.
  > New module 'mbtowc'.
  > wcrtomb: Add more tests for native Windows platforms.
  > wcrtomb: Enhance test.
  > mbrtowc: Tiny optimization.
  > test-exclude.c: remove unmatched #endif
  > git-version-gen: skip "-dirty" check when appropriate
  > unictype/property-byname: Reduce the size of the 'data' segment.
  > unictype/scripts: Reduce the size of the 'data' segment.
