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

[Eric Blake]

Among other recent changes, this includes a workaround to avoid
Clang compiler bug https://llvm.org/bugs/show_bug.cgi?id=16404
having spurious link failures.

* .gnulib: Update.
* bootstrap: Synchronize to upstream.

I'm debating about re-enabling test-lock (right now, we explicitly
pass --avoid=lock-tests to gnulib-tool via our bootstrap.conf), now
that upstream is finally starting to fix the bugs in the test that
were causing extremely slow completion or outright hangs on
multi-processor setups.  But that's probably something better done
right after a libvirt release, not right before a release candidate.

Pushing under the gnulib maintenance rule; contains these gnulib patches:

* .gnulib e210a3c...94386a1 (38):
  > maint.mk: enforce spelling of "timestamp" (i.e., no space)
  > dfa: minor simplification with emptyset
  > dfa: shrink constraints from 4 bits to 3
  > dfa: omit unnecessary ptrdiff_t check
  > dfa: omit unnecessary allocation
  > dfa: omit unused local
  > maint: time stamp -> timestamp
  > maint: remove stray .texi files
  > getprogname: fix port to IRIX
  > dfa: melt down dfastate into build_state
  > dfa: simplify transition table allocation
  > dfa: fix reallocation bug when matching newlines
  > Avoid -Wundef warning about undefined WINDOWS_SOCKETS.
  > Avoid -Wundef warning about undefined __USE_FILE_OFFSET64.
  > stdioext: Port to Minix 3.2 and newer.
  > getprogname: port to IRIX
  > localename-tests: port to NetBSD 7
  > glob, intprops, xalloc: work around Clang bug
  > dfa: fix 'return' typo
  > lock tests: Prefer semaphore over mutex.
  > parse-datetime: fix generated paths for coverage files
  > maint.mk: support parallel execution of coverage
  > lock: Provide guarantee to avoid writer starvation for rwlocks.
  > thread: Fix pth port.
  > parse-datetime: fix debug message on lone year number
  > parse-datetime: fix local timezone debug messages
  > parse-datetime: add debug warning about DST changes
  > parse-datetime: add debug warning about date arithmetic
  > parse-datetime: fix debug message of relative part after timezone
  > parse-datetime: fix incorrect debug message on lone number
  > exec
  > build-aux/mdate-sh
  > doc: fix typo in previous change
  > Revert copyright-year change to synced files
  > doc: modernize for C11 etc.
  > dfa: prefer functions to FETCH_WC macro
  > dfa: narrow more local var scopes
  > dfa: remove duplicate assignment
