* sysdeps/mach/hurd/bits/posix_opt.h: Rewritten with comments and

	multiple inclusion protection.
	(_POSIX_SYNCHRONIZED_IO, _POSIX_FSYNC, _POSIX_MAPPED_FILES,
	_POSIX_MEMORY_PROTECTION, _POSIX_POLL, _POSIX_SELECT): New macros,
	define all these to 1.
	(_POSIX_SYNC_IO): Add #undef, to remind us that pathconf reports it.
