* cygheap.h (struct cwdstuff): Drop hash member. Drop get_hash,

	get_initial, and fixup_after_exec declarations.
	Convert win32 to UNICODE_STRING.
	(cwdstuff::get_drive): Convert win32 path in current codepage.
	(cwdstuff::set): Take native NT path.
	* ntdll.h (struct _TEB): Typedef.
	* path.cc (mount_info::conv_to_posix_path): Add variant taking
	wide char DOS paths.
	(symlink_info::posixify): Simplify concatenating cwd and relative path.
	(hash_path_name): Drop special relative path handling.
	(chdir): Drop special "drive only" handling.  Call cwdstuff::set with
	native path.
	(cwdstuff::get_hash): Remove.
	(windows_system_directory): Remove.
	(_upp): Remove.
	(get_user_proc_parms): Make inline.  Get PEB pointer by calling
	NtCurrentTeb.
	(cwdstuff::init): Simplify.
	(cwdstuff::set): Rework to handle incoming native NT path.  Workaround
	a Vista problem with CWD handle in the user process parameter block.
	(cwdstuff::get): Simplify locking.  Accommodate type change of win32.
	* shared_info.h (mount_info): Add declaration for new conv_to_posix_path
	method.
	* strfuncs.cc (sys_wcstombs): Return correct length of created
	multi-byte string.
