Port write-region-inhibit-sync, allowing avoidance of bad FS performance.
See http://shaver.off.net/diary/2008/05/25/fsyncers-and-curveballs/ for more
details.

Integrate Romain Francoise' 2005-09-14 (pre-GPLV3) GNU change,
which can allow much better performace with some stupid
filesystems:
* fileio.c (write_region_inhibit_fsync): New variable.
(Fwrite_region): Use it to skip call to fsync.
(syms_of_fileio): Initialize it.
