Instead of a failed check or assertion failure and a core dump, let's
produce an error message on stderr and a graceful nonzero exit status.
It's still not going to *work*, but at least we can avoid crashing.

Invalid signal name: Member name was not valid: '0'

Clients listening for a signal can match against the 'sender', expecting
it to come from a connection with a specific name. With this change,
dbus-send can send signals to them.
Switch the order of the argument checks to avoid the
-Wduplicated-branches warning.

It's initialized to a non-trivial value whenever container_type
is DBUS_TYPE_DICT_ENTRY, and subsequently only used if
container_type is DBUS_TYPE_DICT_ENTRY, but Debian's gcc 7.2.0-7
doesn't seem to be able to infer that any more, causing build failure
under -Werror=maybe-uninitialized.

This is a fairly pointless feature to add, since the current behaviour
was to abort due to a NULL pointer dereference shortly after the OOM
failure. At least now people will get a helpful error message when they
try to use dbus-send on a machine with incurable memory pressure.

This commit does several more strictly check for dbus-send as its usage
suggested.
* now --address is an invalid option but --address=, this just like the
others, say --reply-timeout=, --dest=, --type=
* --print-reply= only take an optional argument "=literal"
* --print-reply= will cause error with missing MSEC and invalid MSEC
will cause invalid value error
* --dest= will cause error with missing a NAME and also call
dbus_validate_bus_name to verify the NAME

that maps a base name to a list of names it owns (that we're
interested in). Add pending_nameowner_calls which is a list of

proxies with no associated name owner.

(got_name_owner_cb): New function.
(get_name_owner): New function, extracted from
dbus_g_proxy_new_for_name_owner.
(dbus_g_proxy_manager_register): For now we need to keep track of
all NameOwnerChanged. Also if the proxy is for a name, if we
don't already know the name owner, queue a new GetNameOwner
request and add it to our list of unassociated proxies. Otherwise
inc the refcount.
(dbus_g_proxy_manager_unregister): If this proxy is for a name,
cancel any pending GetNameOwner call, etc.
(dbus_g_proxy_manager_filter): Handle NameOwnerChanged. Also use
the owner_names mapping to look up the current names for the
signal source, and dispatch to any proxies for that name.
(dbus_g_proxy_new): Initialize new members.
(dbus_g_proxy_new_for_name): Delete unused proxy variable.
(dbus_g_proxy_new_for_name_owner): Use get_name_owner.
(dbus_g_pending_call_end_valist): New function, extracted from

but want to use the GLib infrastructure. Also note how many
arguments in reply were over.
(dbus_g_pending_call_end): New function, just call
dbus_g_pending_call_end_valist.
(dbus_g_proxy_end_call_internal): Just call
dbus_g_pending_call_end_valist.

of builtin marshaller for STRING_STRING_STRING.
* test/glib/test-dbus-glib.c:
* test/glib/test-service-glib.c:

Extend tests to cover name proxies, destruction of owner proxies,

to message.
* tools/dbus-send.c (append_array): New function.
(append_arg): Broken out from main.
(main): Add cheesy hack to send arrays and variants.
(usage): Update.
* tools/dbus-print-message.c (print_iter): Broken out
from main.
* Throughout, grand renaming to strip out the use of "service",
just say "name" instead (or "bus name" when ambiguous). Did not
change the internal code of the message bus itself, only the
programmer-facing API and messages.
* doc/dbus-specification.xml: further update the message bus section
* bus/config-parser.c (all_are_equiv): fix bug using freed string
in error case
* 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.
* 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
* 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

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
