Suggest there should at least be accessors, rather than encouraging
direct use of a magic object data name. But it's also an inherently
unthreadsafe approach... maybe thread-local data? I swear we had a list
thread a while back about how to do this though, with some conclusion.

Suggest naming it to exactly match the dbus method, though
get_connection_unix_process_id() is long... dbus-bus.h is unfortunately
very ad hoc, but ideally let's not make it worse with new methods.

I'm kind of tempted to say let's kill dbus-bus.h in favor of having
people generate it for their bindings. Or rather, I'm almost 100% sure
dbus-bus.h should only have dbus_bus_get() and friends, no convenience
methods. But it's not as simple as just deleting them since the new
binding APIs would have to be added also.
