	impersonation token.
	(cygheap_user::reimpersonate): Set processes' or setuid token as
	necessary.
	(cygheap_user::has_impersonation_tokens): Look for curr_primary_token
	value.
	(cygheap_user::close_impersonation_tokens): Close curr_primary_token
	here if necessary.  Don't reset token values to NO_IMPERSONATION since
	that's done in uinfo_init anyway.
	(init_cygheap::luid): New LUID array keeping privilege LUIDs.
	* cygtls.cc (_cygtls::init_thread): Call cygheap->user.reimpersonate.
	* dcrt0.cc (hProcToken): New global variable to keep process token.
	(hProcImpToken): Ditto for process impersonation token.
	(dll_crt0_0): Open process token here once.  Duplicate to create
	hProcImpToken.
	(dll_crt0_1): Call set_cygwin_privileges.
	* environ.cc (allow_ntea): Drop duplicate declaration.
	(allow_smbntsec): Ditto.
	(set_traverse): Only set allow_traverse here.

	(fhandler_disk_file::facl): Ditto.
	* fork.cc (fork_child): Move call to cygheap->user.reimpersonate after
	syn with parent. Call set_cygwin_privileges.
	* grp.cc (internal_getgroups): Use hProcImpToken instead of opening
	process token.
	* path.cc (fs_info::update): Bypass traverse checking when retrieving
	volume information using push/pop_thread_privileges.
	* registry.cc (load_registry_hive): Drop setting restore privilege
	since it's already set if available.
	* sec_helper.cc: Include cygtls.h.
	(cygpriv): Privilege string array.
	(privilege_luid): New function, evaluate LUID from cygpriv_idx.
	(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.

	cygheap->user.deimpersonate instead of RevertToSelf.  Create
	impersonation token from primary internal or external token.  Set

	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.
