* Land the new message args API and type system.

	This patch is huge, but the public API change is not
	really large. The set of D-BUS types has changed somewhat,
	and the arg "getters" are more geared toward language bindings;
	they don't make a copy, etc.

	There are also some known issues. See these emails for details
	on this huge patch:
	http://lists.freedesktop.org/archives/dbus/2004-December/001836.html
        http://lists.freedesktop.org/archives/dbus/2005-January/001922.html

	* dbus/dbus-marshal-*: all the new stuff

	* dbus/dbus-message.c: basically rewritten

	* dbus/dbus-memory.c (check_guards): with "guards" enabled, init
	freed blocks to be all non-nul bytes so using freed memory is less
	likely to work right

	* dbus/dbus-internals.c (_dbus_test_oom_handling): add
	DBUS_FAIL_MALLOC=N environment variable, so you can do
	DBUS_FAIL_MALLOC=0 to skip the out-of-memory checking, or
	DBUS_FAIL_MALLOC=10 to make it really, really, really slow and
	thorough.

	* qt/message.cpp: port to the new message args API
	(operator<<): use str.utf8() rather than str.unicode()
	(pretty sure this is right from the Qt docs?)

	* glib/dbus-gvalue.c: port to the new message args API

	* bus/dispatch.c, bus/driver.c: port to the new message args API

	* dbus/dbus-string.c (_dbus_string_init_const_len): initialize the
	"locked" flag to TRUE and align_offset to 0; I guess we never
	looked at these anyhow, but seems cleaner.

	* dbus/dbus-string.h (_DBUS_STRING_ALLOCATION_PADDING):
	move allocation padding macro to this header; use it to implement
	(_DBUS_STRING_STATIC): ability to declare a static string.

	* dbus/dbus-message.c (_dbus_message_has_type_interface_member):
	change to return TRUE if the interface is not set.

	* dbus/dbus-string.[hc]: move the D-BUS specific validation stuff
	to dbus-marshal-validate.[hc]

	* dbus/dbus-marshal-basic.c (_dbus_type_to_string): move here from
	dbus-internals.c

	* dbus/Makefile.am: cut over from dbus-marshal.[hc]
	to dbus-marshal-*.[hc]

	* dbus/dbus-object-tree.c (_dbus_decompose_path): move this
	function here from dbus-marshal.c

HACKING

@ -127,6 +127,17 @@ dbus_realloc to fail if the number of bytes to be allocated is greater
than the specified number. This only works if D-BUS has been compiled with
--enable-tests.
DBUS_TEST_MALLOC_FAILURES=n
Many of the D-BUS tests will run over and over, once for each malloc
involved in the test. Each run will fail a different malloc, plus some
number of mallocs following that malloc (because a fair number of bugs
only happen if two or more mallocs fail in a row, e.g. error recovery
that itself involves malloc). This env variable sets the number of
mallocs to fail.
Here's why you care: If set to 0, then the malloc checking is skipped,
which makes the test suite a heck of a lot faster. Just run with this
env variable unset before you commit.

they are invalid for the wrong reasons due to protocol changes.

invalid for right reason, e.g. an "INVALID_ERROR Foo" line
in the message files)
- the "break loader" and valid/invalid message tests are all disabled;
they need to be fixed and re-enabled with the new message args stuff.

- re_align_field_recurse() in dbus-message.c is broken because it
crashes on some types of header field values. security problem.
- modify the wire protocol to keep the args signature separate
from the args themselves. Make the name of TYPE_CUSTOM part
of the type signature, rather than part of the value.
Then you have the full typecheck in a single string.
See http://freedesktop.org/pipermail/dbus/2004-June/001169.html
Subnote: STRING_OR_NIL is wrong, doesn't work in C++ etc. ; should
not have done that. Use empty string or special string values or separate functions/signals
or whatever instead.
Subnote: For recursive types, one approach is that "structs" are done as parens,
so e.g. s(ii) is a string and struct { int; int; } etc. Type codes
then all have to be done as strings not single ints.
We could also put the type signature for the message body in a
header field.
An "any" type has the type string included in the value.
- need to define bus behavior if you send a message to
yourself; is it an error, or allowed? If allowed,
we need to have a test for it in the test suite.
