Commit 1726a73 hacked around MacOS' lack of fdatasync, since
gnulib did not have it at the time.  But now that we use newer
gnulib, we can avoid the hack.

* bootstrap.conf (gnulib_modules): Add fdatasync.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop our own check.

BTW, are there any plans on enhancing gnulib fsync module to provide a
replacement for certain versions of OS X? Although they provide fsync, it
doesn't really sync anything and one needs to do some ioctl hackery to really
achieve what fsync should do.

Any quick pointers to example code using that ioctl? Then again, I'll probably find them with a quick google search myself.

Yes, gnulib should be taught to make fsync() more useful on OS X.
