Merge branch 'pe/time-use-gettimeofday'

Browse Source 
time(2) on glib 2.31+, especially on Linux, goes out of sync with
higher resolution timers used for gettimeofday(2) and by the
filesystem.  Replace all calls to it with a git_time() wrapper and
use gettimeofday(2) in its implementation.

* pe/time-use-gettimeofday:
  git-compat-util: use gettimeofday(2) for time(2)
