	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.

	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.
