gmain: Add GMainContextPusher convenience API

Browse Source 
This is like `GMutexLocker`, in that if you are able to use
`g_autoptr()`, it makes popping a `GMainContext` off the thread-default
main context stack easier when exiting a function.

A few uses of `G_GNUC_{BEGIN,END}_IGNORE_DEPRECATIONS` are needed to
avoid warnings when building apps against GLib with
`GLIB_VERSION_MAX_ALLOWED < GLIB_VERSION_2_64`.
