* dbus/dbus-glib-error-enum.h: autogenerate the GError enum
codes from the dbus error names
* glib/dbus-glib.h: move to subdir dbus/ since it's included
as dbus/dbus-glib.h and that breakage is now visible due to
including dbus/dbus-glib.h in dbus-glib-lowlevel.h
* glib/dbus-glib.h: s/gproxy/g_proxy/
* dbus/dbus-shared.h: new header to hold stuff shared with
binding APIs
* dbus/dbus-protocol.h (DBUS_ERROR_*): move errors here rather
than dbus-errors.h
* glib/dbus-glib.h (dbus_set_g_error): move to
dbus-glib-lowlevel.h
* glib/dbus-glib.h: remove dbus/dbus.h from here; change a bunch
of stuff to enable this
* dbus/dbus-glib-lowlevel.h: put dbus/dbus.h here
* a bunch of other changes with the same basic "separate glib
bindings from dbus.h" theme
* glib/dbus-gidl.c (method_info_add_arg): keep args sorted with
"in" before "out"
* glib/dbus-gobject.c (dbus_type_to_string): move to dbus-gutils.c
* glib/dbus-glib-tool.c (main): set up to have a --self-test
option that runs the tests, and start filling in some code
including for starters just dumping the interfaces to stdout
* glib/Makefile.am (INCLUDES): define DBUS_LOCALEDIR
* test/data/valid-introspection-files/lots-of-types.xml: test of
an example introspection file
* glib/dbus-gparser.c (parser_check_doctype): doctype should be
"node" (I think...)
