GApplication in Garbage Collected environments would benefit from a g_application_command_line_exit() to enable remote instances to exit.

Submitted by Andrew Cowie

Description

The behaviour of the "command line" capability in GApplication is defined as depending on the lifecycle of the GApplicationCommandLine object.

This is challenging in memory-managed environments because we do not control when the last reference will be dropped by the runtime; although we may have dropped our last reference the runtime will be holding a weak (ie GToggleRef last_ref) reference count to the object, and it may be quite some time before the garbage collector runs to drop this last ref, leading to GObject disposal.

g_application_command_line_exit() or so would allow us to indicated that we have finished processing the arguments, and more importantly, wish the remote to terminate.
