[glibmm] Glib::MainContext: Deprecate wait(cond, mutex).

[Murray Cumming <murrayc src gnome org>]

commit 2f508058e9d8b790a66738335c47ea31d90f0b3d

    Glib::MainContext: Deprecate wait(cond, mutex).
    
    Because it uses the deprecated Threads API in its API, and doesn't
    seem generally useful.
    As suggested here:
