Either child_watch_source or timeout_source will already have been
destroyed after we finish the loop, and it's not safe to call
g_source_destroy() on it a second time unless we're still holding a
ref on it.
Like how we're handling activation, use GVariant for timestamps. To
avoid polluting the GtkApplication API with GVariants, we rename the
GApplication signals to "quit-with-data" and "action-with-data".
GtkApplication will then wrap those as just "quit" and "action".

Create a function run_with_application that both ensures the
app is running exactly while the test is running, which most
of the tests use. We start it beforehand, and kill it after.
This avoids having any interdependence between the tests (and
there definitely was before, because we didn't wait for
the process to actually terminate after a kill() call).
Also, open a pipe between the two, and have the child app
monitor that pipe. If it gets closed (e.g. because the parent
died), the child exits. This is the most reliable way to
avoid stale children; before, if we failed an assertion, the
parent would abort, and not run kill().

This adds a GApplication object to GIO, which is the core of
an application support class, supporting
- uniqueness
- exporting actions (simple scripting)
- standard actions (quit, activate)
The implementation for Linux uses D-Bus, takes a name on the
session bus, and exports a org.gtk.Application interface.
Implementations for Win32 and OS X are still missing.
