If all users of a GThreadedSocketService release their references to the
service while a connection thread is running, the thread function will
release the last reference to the service which causes the finalize to
deadlock waiting for all threads to finish (because it's called from the
thread function).
To fix this, don't wait for all threads to finish in the service's
finalize method. Since the threads hold a reference to the service,
finalize should only be called when all threads are finished running (or
have unrefed the service and are about to finish).

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
To help cross compilation, don't use glib-genmarshal in our
build. This is easy now that we have g_cclosure_marshal_generic().
In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).
In gio/, simply switch to using g_cclosure_marshal_generic().
