set_security_attribute appropriately.
	* external.cc (cygwin_internal): Ditto.
	* fhandler.cc (fhandler_base::open): Ditto.
	* fhandler_socket.cc (fhandler_socket::bind): Ditto.
	* path.cc (symlink_worker): Ditto.
	* sec_acl.cc (setacl): Ditto. Call read_sd appropriately.
	(getace): Ditto.
	* sec_helper.cc (security_descriptor::malloc): New method.
	(security_descriptor::realloc): New method.
	(security_descriptor::free): New method.
	* security.cc (read_sd): Get security_descriptor as parameter instead
	of PSECURITY_DESCRIPTOR and a size. Drop unnecessary parameter check.
	Allocate the security_descriptor buffer according to size returned by
	a call to GetFileSecurity. Return buffer size on success.
	(write_sd): Get security_descriptor as parameter instead of
	PSECURITY_DESCRIPTOR and a size.
	(get_nt_attribute): Use local security_descriptor.
	(get_nt_object_attribute): Ditto in case of type == SE_REGISTRY_KEY.
	Allocate security_descriptor buffer according to size returned by
	a call to RegGetKeySecurity.
	(alloc_sd): Make static. Get security_descriptor as parameter instead
	of PSECURITY_DESCRIPTOR and a size. Drop unnecessary parameter check.
	(set_security_attribute): Get security_descriptor as parameter instead
	of PSECURITY_DESCRIPTOR and a size.
	(set_nt_attribute): Use local security_descriptor.
	(check_file_access): Ditto.
	* security.h: Add class security_descriptor.
	(read_sd): Change declaration to get security_descriptor as parameter
	instead of PSECURITY_DESCRIPTOR and a size.
	(write_sd): Ditto.
	(set_security_attribute): Ditto.
	(alloc_sd): Remove declaration.
	* thread.cc (semaphore::semaphore): Use local security_descriptor. Call
	set_security_attribute appropriately.
