Merge branch 'pe/time-use-gettimeofday'

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)
