	since it's already set if available.

	(privilege_luid_by_name): New function, evaluate LUID from privilege
	string.
	(privilege_name): New function, evaluate privilege string from
	cygpriv_idx.
	(set_privilege): New static function called by set_process_privilege
	and set_thread_privilege.  Call privilege_luid to get privilege LUID.
	Fix bug in return value evaluation. Improve debug output.

	(set_process_privilege): Remove.
	(enable_restore_privilege): Remove.
	* security.cc (allow_traverse): New global variable.
	(sys_privs): Change type to cygpriv_idx and store privilege indices
	instead of strings.
	(SYSTEM_PRIVILEGES_COUNT): Renamed from SYSTEM_PERMISSION_COUNT.
	(get_system_priv_list): Don't use numerical constant in malloc call.
	Use privilege_luid to get privilege LUIDs.
	(get_priv_list): Call privilege_luid_by_name to get LUIDs. Improve
	inner privilege LUID comparison loop.
	(create_token): Enable create token privilege using
	push/pop_self_privileges. Use hProcToken instead of opening process
	token. Use default DACL when duplicating token.
	(subauth): Enable tcb privilege using push/pop_self_privileges.
	Use sec_none instead of homw made security attributes when duplicating
	token.
	(check_file_access): Don't duplicate access token, use active
	impersonation token as is.
	* security.h (enum cygpriv_idx): New enumeration type enumerating
	possible privileges.
	(privilege_luid): Declare new function.
	(privilege_luid_by_name): Ditto.
	(privilege_name): Ditto.
	(allow_traverse): Declare.
	(set_privilege): Declare function.
	(set_process_privilege): Define as macro.
	(enable_restore_privilege): Remove declaration.
	(_push_thread_privilege): Define macro.
	(push_thread_privilege): Ditto.
	(pop_thread_privilege): Ditto.
	(pop_self_privilege): Ditto.
	* spawn.cc (spawn_guts): Use cygheap->user.primary_token instead of
	cygheap->user.token.
	* syscalls.cc (statvfs): Bypass traverse checking when retrieving
	volume information using push/pop_thread_privileges. Rearrange code
	to simplify push/pop bracketing.
	(seteuid32): Use hProcToken instead of opening process token. Call
	cygheap->user.deimpersonate instead of RevertToSelf.  Create
	impersonation token from primary internal or external token.  Set
	cygheap->user.curr_primary_token and cygheap->user.current_token
	privileges once here.  Drop "failed" and "failed_ptok" labels.
	Drop setting DefaultDacl of process token.
	(setegid32): Use hProcToken and hProcImpToken instead of opening
	process token. Always reimpersonate afterwards.
	* uinfo.cc (cygheap_user::init): Use hProcToken instead of opening
	process token.
	(internal_getlogin): Ditto. Set hProcImpToken, too.
	(uinfo_init): Initialize cygheap->user.curr_primary_token.
	* winsup.h (hProcToken): Declare.
