Cleanup.

	* exceptions.cc (windows_system_directory): Make static.  Convert to
	WCHAR.
	(_cygtls::inside_kernel): Accommodate above change.  Check module
	path name for leading \\?\ and skip, if so.
	(try_to_debug): Call GetEnvironmentStringsW and convert evaluation to
	WCHAR to avoid truncated environment problem.
	(has_visible_window_station): Call GetUserObjectInformationW.
	(events_init): Accommodate above conversion of windows_system_directory.
	* init.cc (respawn_wow64_process): Use WCHAR functions to start new
	process.
	* net.cc (__dup_ent): Drop Windows 9x consideration.
	(load_ipv6_funcs): Use WCHAR functions to load IPv6 libs.
	* syscalls.cc (syscalls.cc): Remove call to GetDiskFreeSpace.
