* devices.in: Throughout use slashes instead of backslashes in the

native path of devices not backed by native NT devices.
	* devices.cc: Regenerate.
	* globals.cc (ro_u_pmem): Use correct case.
	(ro_u_globalroot): New R/O unicode string.
	* path.cc (path_conv::check): Fix incorrect handling of /proc/sys
	block devices if they are just visited due to a component check.
	(symlink_info::posixify): Fix typo in comment.
	(cygwin_conv_path): Use ro_u_globalroot instead of string constant.
	(fast_cwd_version): New shared variable to store FAST_CWD version
	used on the system.
	(find_fast_cwd_pointer): Rename from find_fast_cwd_pointers.  Don't
	set global fast_cwd_ptr pointer here.  Return pointer value instead.
	(find_fast_cwd): New function to set fast_cwd_ptr and fast_cwd_version.
	(cwdstuff::override_win32_cwd): Call find_fast_cwd from here.
	Check for fast_cwd_version to differ between old and new FAST_CWD
	structure.  Check old_cwd for NULL to avoid SEGV.  Don't set CWD if
	we have neitehr a valid fast_cwd_ptr, nor a valid CWD handle in the
	process parameter block.
	(cwdstuff::set): Create Win32 path taking /proc/sys paths into account.
	* spawn.cc (spawn_guts): Recode creating runpath.  Also take /proc/sys
	paths into account.  Drop special CWD handling when starting non-Cygwin
	processes.
