* dbus/dbus-string.c (_dbus_string_align_length): new function

	* dbus/dbus-test-main.c: move main() for test app here
	* dbus/dbus-test.c
	(dbus_internal_symbol_do_not_use_run_tests): we have to export a
	symbol to run tests, because dbus-test isn't in the main
	library

        Code review nitpicks.

	* dbus/dbus-message.c (dbus_message_write_header): add newlines
	for people with narrow emacs ;-). Assert client_serial was filled
	in. Assert message->name != NULL.
	(dbus_message_append_fields): have "first_field_type" arg separate
	from va list, needed for C++ binding that also uses varargs IIRC
	and helps with type safety
	(dbus_message_new): add @todo about using DBusString to store
	service/name internally
	(dbus_message_new): don't leak ->service and ->name on OOM later
	in the function
	(dbus_message_unref): free the service name
	(dbus_message_get_fields): same change to varargs
	i.e. first_field_type
	(_dbus_message_loader_return_buffer): assert that the message data
	is aligned (if not it's a bug in our code). Put in verbose griping
	about why we set corrupted = TRUE.
	(decode_header_data): add FIXME that char* is evil.  Was going to
	add FIXME about evil locale-specific string.h strncmp, but just
	switched to wacky string-as-uint32 optimization. Move check for
	"no room for field name" above get_const_data_len() to avoid
	assertion failure in get_const_data_len if we have trailing 2
	bytes or the like. Check for service and name fields being
	provided twice. Don't leak service/name on error. Require field
	names to be aligned to 4 bytes.

	* dbus/dbus-marshal.c: move byte swap stuff to header
	(_dbus_pack_int32): uscore-prefix
	(_dbus_unpack_int32): uscore-prefix
	(_dbus_unpack_uint32): export
	(_dbus_demarshal_string): add @todo complaining about use of
	memcpy()
	(_dbus_marshal_get_field_end_pos): add @todo about bad error
	handling allowing corrupt data to go unchecked
