[Spice-devel] [PATCH 14/17] Remove global main_dispatcher variable
Frediano Ziglio

Thu Feb 11 19:24:13 UTC 2016
From: Jonathon Jongsma <jjongsma at redhat.com>
Requires changing a bunch of internal API to take MainDispatcher
arguments, etc. The main dispatcher object is now owned by RedsState,
since that is the object that previously created (initialized) it.
