* python/dbus_bindings.pyx: Repair my previous commit which reverted
part of the preceding one. Oops. Merge patch by Johan Hedberg
<johan.hedberg@nokia.com> to fix marshalling of 16-bit integer values
on big-endian platforms.
* test/python/test-client.py: Add some 16-bit integers to the test
values.

* python/dbus_bindings.pyx: Fix a bug where doing a strict append
with type v of an instance of dbus.Variant(foo, type='x') caused
it to be boxed twice before sending over the bus.
* python/dbus_bindings.pyx, python/service.py,
test/python/test-client.py: Update the constants for the new
request_name flags, and update comments/test cases now that queueing
is the default action.

* bus/driver.c, bus/services.c, bus/services.h: Add a ReleaseName
method to org.freedesktop.DBus to release a bus name or give up
waiting in the queue for it.
* dbus/dbus-bus.c, dbus/dbus-bus.h, dbus/dbus-shared.h: Add a
dbus_bus_release_name method to send the ReleaseName method calls.
Add constants for the return values to dbus/dbus-shared.h.
* doc/dbus-specification.xml: Document the new ReleaseName method
in the specification.
* python/dbus_bindings.pyx: Add a low-level python binding for the
release name method.
* python/exceptions.py, python/service.py: Make freeing BusName
objects release the name. Add a NameExistsException, and fix a
bug with creating UnknownMethodException.
* test/python/test-client.py: Add tests for freeing BusName
objects causing names to be released.

* python/decorators.py, python/service.py: Add a new argument to the
dbus.service.method decorator called sender_keyword, which if set,
specifies the name of an argument which will be provided the bus
name of the method caller.
* test/python/test-client.py, test/python/test-service.py: Add a
method and test to check the sender_keyword functionality.

* python/decorators.py: Change emit_signal function to use the
signature annotation of the signal when marhsalling the arguments from
the service. Fix a bug where the code checking signature length
against argument length referenced the wrong variable.
* python/introspect_parser.py: Avoid adding the type signature of
signal arguments to any methods which occur after them in the
introspection data (!) by making the parser a little more careful
about its current state.
* python/service.py: Remove debug prints from last commit (again :D).
* test/python/test-client.py, test/python/test-service.py: Add test
signals with signature decorators to test the strict marshalling code
gives errors at the right time. Could do with checking the signals
actually get emitted too, given that the test does nothing with
signals at the moment...

* python/_dbus.py: Add WeakReferenceDictionary cache of dbus.Bus
instances to stop madness of creating new instances representing
the same bus connection all the time, rendering any tracking of
match rules and bus names quite meaningless. Caught a bug where
the private argument to SessionBus() and friends was being passed
in as use_default_mainloop by mistake. Still some problems with
multiple dbus_binding.Connection instances representing the same
low-level connection (eg when you use both SessionBus() and
StarterBus() in same process), but it's a lot better now than it
was.
* python/dbus_bindings.pyx: Add constants with the return values
for bus_request_name().
* python/service.py: Store bus name instances in a per-dbus.Bus cache
and retrieve the same instances for the same name, so deletion can be
done with refcounting. Also now throws some kind of error if you
don't actually get the name you requested, unlike previously...
* test/python/test-client.py: Add tests for instance caching of buses
and bus name objects.

* python/dbus_bindings.pyx, test/python/test-client.py: Fix
marshalling of boolean values. Add some booleans to the values in
the test client.
* python/decorators.py, python/service.py: Add an 'async_callbacks'
argument to the dbus.service.method decorator, which allows you to
name arguments to take two callback functions for replying with
return values or an exception.
* test/python/test-client.py, test/python/test-service.py: Add test
case using asynchronous method reply functions, both return values and
errors, and from within both the function itself and from a mainloop
callback.
* python/decorators.py, python/service.py: Perform checking that the
number of method/signal arguments matches the number of types in the
signature at class loading time, not when you first introspect the
class.
* python/service.py: Remove debug print left by the last commit.

* python/service.py: Heavy refactoring of method invocation, with
hopefully no effect on functionality. Nuked _dispatch_dbus_method_call
in favour of a new _message_cb that uses seperate functions for
looking up the method to call, marshalling the return values, and
sending exceptions as errors, and is easier to follow as a
consequence. Fixes some corner cases about returning things that
don't match your declared out_signature, allows exceptions to define
_dbus_error_name and have it be sent over the bus as the error name,
and paves the way for cool stuff like heeding the message no reply
flag, asynchronous method implementations, informing the method of the
sender, and including backtraces in the error messages.
* test/python/test-client.py: Catch and print exceptions thrown in the
async callback tests, rather than passing them to the low-level
bindings to be ignored in a noisy and frustrating manner.

* python/_dbus.py, python/proxies.py, python/service.py: Add __repr__
functions to dbus.Bus, dbus.service.BusName and dbus.service.Object,
tweak others to be consistent.
* test/python/test-client.py: Tweak output of testInheritance.

* python/service.py: Major changes to allow multiple inheritance
from classes that define D-Bus interfaces:
1. Create a new Interface class which is the parent class of
Object, and make the ObjectType metaclass into InterfaceType.
2. Patch written with Rob Taylor to replace use of method_vtable
with code that walks the class's __MRO__ (method resolution order)
to behave like Python does when invoking methods and allow
overriding as you'd expect. Code is quite tricky because
we have to find two methods, the one to invoke which has the
right name and isn't decorated with the /wrong/ interface,
and the one to pick up the signatures from which is decorated
with the right interface.
The same caveats apply as to normal multiple inheritance -
this has undefined behaviour if you try and inherit from two
classes that define a method with the same name but are
decorated with different interfaces. You should decorate
your overriding method with the interface you want.
3. Replace grungy introspection XML generation code in the metaclass
with dictionaries that cope correctly with multiple inheritance
and the overriding of methods. This also uses the signature
decorations to provide correct introspection data, including
the debut appearance of the types of your return values. :D
* test/python/test-client.py, test/python/test-service.py: Add a test
case to try invoking an method that overrides one inherited from a
D-Bus interface class.

* python/decorators.py: Add optional arguments to the method and
signal decorators to allow you to specify the signature of arguments
and return values. Preserve the doc strings of signal functions in the
decorated version, for pydoc and friends.
* python/dbus_bindings.pyx, python/proxies.py: Replace the
parse_signature_block function with an iterable dbus.Signature()
type. Fix a bug in MessageIter.append_strict where you could append
anything by claiming it was a string.
* python/service.py: Use the out_signature decoration on methods to
marshal return values, meaning you no longer require dbus.Array()
or dbus.Dictionary() to indicate the type when returning empty
arrays or dictionaries. Fix a bug where exceptions which are defined
in __main__ are not turned into error replies.
* test/python/test-client.py, test/python/test-service.py: Add test
for correct marshalling of return values according to out_signature.
Fix a bug in the async call test where the error_handler is missing a
self argument.

STRUCT_BEGIN not TYPE_STRUCT in indicate we are marshalling a struct
* python/service.py (Object::_message_cb): handle exceptions correctly
by sending them over the wire to the calling app. This makes sure
the client returns immediately instead of waiting the 15 seconds to
timeout.
* test/python/test-client.py (TestDBusBindings::testBenchmarkIntrospect):
Add a test to benchmark how long it takes to introspect a service and
call a method which returns a large element (pretty fast)

instead of marshal basic so we can handle recursive types in a variant
* test/glib/test-dbus-glib.c: Add test for marshaling recurive types
in variants
* test/glib/test-service-glib.c, test-service-glib.xml
(my_object_echo_variant [EchoVariant],
my_object_process_variant_of_array_of_ints123
[ProcessVariantOfArrayOfInts123]):
Add two test methods
* python/introspect_parser.py: New module for parsing introspect
data.
* python/dbus_bindings.pyx:
(various places): when throwing errors fix to use errormsg instead
of message local variable because Pyrex can get confused with other
message variables (initial patch by Robert McQueen
<robert.mcqueen at collabora.co.uk>)
(MessageIter::parse_signature_block): new method for getting the next
block in a signiture.
(MessageIter::append_strict): new method for appending values strictly
using the passed in signature instead of guessing at the type
(MessageItter:: append_dict, append_struct, append_array): use
signatures to marshal children if the signature is available
* python/exceptions.py (IntrospectionParserException): new exception
* python/proxies.py (ProxyMethod::__call__): Marshal args with
introspected signatures if available, else we fall back to the
old way of doing things.
(ProxyObject::_introspect_reply_handler ): parse introspection data
* python/service.py (ObjectType::_reflect_on_method): Properly
terminate <method> if there are no args in the reflection data
* test/python/test-client.py: add tests for talking with the GLib
test server. This gives us better coverage for introspection since
python to python will always generate arguments as variants. It also
allows us to test the robustness of the GLib bindings and interlanguage
communications.
