The rules are:
* symbols in libdbus-1 with neither decoration are private to libdbus-1
* symbols in libdbus-1 with DBUS_EXPORT are public API
* symbols in libdbus-1 with DBUS_PRIVATE_EXPORT are private to the
dbus source package, but may be used by other programs in the dbus
source tree, including tests
* symbols in libdbus-internal must not have DBUS_EXPORT or
DBUS_PRIVATE_EXPORT, and should be used by as few things as possible
Thanks to Ralf Habacker for his contributions to this rather
large commit.

This has been a soft requirement since 1.5.0; anyone on such platforms
would have had to configure --without-64-bit, provoking a warning that
instructed them to report a D-Bus bug with details of their platform.
Nobody has done so, so if anyone still lacks a 64-bit integer type,
they're on their own.
(Also, I tried the build with --without-64-bit and it's full of
fatal compiler warnings, so it's not clear that we're actually
losing anything by removing this "feature".)

In practice, D-Bus bindings end up reinventing DBusBasicValue anyway,
so it might as well be API.
Also stop claiming that all basic-typed values are guaranteed to fit in
8 bytes - this is not true if your platform has more than 8-byte pointers
(I'm not aware of any such platform now, but let's not rule it out).

This is just as useful for bindings as dbus_signature_validate, and I
think it's a good design principle to say that anything checked in a
_dbus_return_if_fail should be something the caller could check
for themselves.

glibc knows three bswap_{16|32|64}() calls that internally make use of a
gcc extension to implement faster byteswapping. We should make use of it
if we can.
These header files include config.h explicitly anyway. These checks are
hence pointless.
Of course one could argue that including config.h from header files
sucks, but D-Bus generally seems not to have a problem with that, so
let's unify this.
* dbus/dbus-signature.c: New file; implements various functions
related to type signatures. Includes an interator for parsing,
validation functions.
(dbus_type_is_basic): Moved here from
dbus-marshal-basic.c:_dbus_type_is_basic.
(dbus_type_is_container): Moved here from
dbus-marshal-basic.c:_dbus_type_is_container.
All callers of _dbus_type_is_container and _dbus_type_is_basic
updated, and include dbus-signature.h.
* dbus/dbus-signature.h: New file; prototypes for the above.
* dbus/Makefile.am (DBUS_LIB_SOURCES): Add dbus-signature.c,
dbus-signature.h.
* dbus/dbus-marshal-basic.c (map_type_char_to_type): New utility
function factored out of _dbus_first_type_in_signature.
(_dbus_first_type_in_signature_c_str): New function; returns first
type code for a type signature character.
* dbus/dbus-marshal-basic.h: Prototype _dbus_first_type_in_signature_c_str,
handle function moves.
* dbus/dbus-marshal-recursive.h: Export _dbus_type_signature_next.
* dbus/dbus-marshal-recursive.c (_dbus_type_signature_next): New
function; skips to next complete type in type signature.
Implemented using previous skip_one_complete_type. Now
skip_one_complete_type just delegates to
_dbus_type_signature_next.
* dbus/dbus-marshal-basic.c (_dbus_type_is_basic): Moved
to dbus-signature.c
(_dbus_type_is_container): Ditto.
* doc/dbus-specification.xml: Update introspection sample to
use real type signatures.
* dbus/dbus-test.h: Prototype signature test.
* dbus/dbus-test.c (dbus_internal_do_not_use_run_tests): Run
signature tests.
* dbus/dbus-protocol.h (DBUS_ERROR_INVALID_SIGNATURE): New error.
* dbus/dbus-arch-deps.h.in: add 16/32-bit types
* configure.in: find the right type for 16 and 32 bit ints as well
as 64
* dbus/dbus-protocol.h (DBUS_TYPE_INT16, DBUS_TYPE_UINT16): add
the 16-bit types so people don't have to stuff them in 32-bit or
byte arrays.
* dbus/dbus-message.c: byteswap the message if you init an
iterator to read/write from it
* dbus/dbus-marshal-byteswap.c: new file implementing
_dbus_marshal_byteswap()
* dbus/dbus-marshal-basic.c: add _dbus_swap_array()
* Throughout, align variant bodies according to the contained
type, rather than always to 8. Should save a fair bit of space in
message headers.
* dbus/dbus-marshal-validate.c (_dbus_validate_body_with_reason):
fix handling of case where p == end
* doc/TODO: remove the dbus_bool_t item and variant alignment items
* dbus/dbus-types.h: hardcode dbus_bool_t to 32 bits
* Throughout: modify DBUS_TYPE_BOOLEAN to be a 32-bit type instead
of an 8-bit type. Now dbus_bool_t is the type to use whenever you
are marshaling/unmarshaling a boolean.
This is about it on what can be disabled/deleted from libdbus
easily, back below 150K anyhow. Deeper cuts are more work than
just turning the code off as I've done here.
* dbus/dbus-marshal-basic.c (_dbus_pack_int32): we don't need the
signed int convenience funcs
* dbus/dbus-internals.c (_dbus_verbose_real): omit when not in
verbose mode
* dbus/dbus-string-util.c, dbus/dbus-string.c: more breaking
things out of libdbus
* dbus/dbus-sysdeps.c, dbus/dbus-sysdeps-util.c: same
* dbus/dbus-hash.c: purge the TWO_STRINGS crap (well, make it
tests-enabled-only, though it should probably be deleted)
* dbus/dbus-message-util.c: same stuff
* dbus/dbus-auth-util.c: same stuff
* Add and fix docs according to Doxygen warnings throughout
source.
* dbus/dbus-marshal-recursive.c
(_dbus_type_reader_array_is_empty): change this to just call
array_reader_get_array_len() and make it static
* dbus/dbus-message.c (dbus_message_iter_get_element_type): rename
from get_array_type
(dbus_message_iter_init_append): rename from append_iter_init
* dbus/dbus-marshal-recursive.c
(_dbus_type_reader_get_element_type): rename from
_dbus_type_reader_get_array_type
* test/glib/test-profile.c (with_bus_server_filter): fix crash
* dbus/dbus-marshal-basic.c (_dbus_unpack_uint32): inline as macro
when DBUS_DISABLE_ASSERT
(_dbus_marshal_set_basic): be sure we align for the string length
* dbus/dbus-marshal-recursive.c (skip_one_complete_type): make
this look faster
* dbus/dbus-string.c (_dbus_string_get_const_data_len): add an
inline macro version
(_dbus_string_set_byte): provide inline macro version
* 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.htmlhttp://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.

function here from dbus-marshal.c
- add SIGNATURE type
- fix max name len of 256, should be 255 so it fits in a byte if it's going to be a number
