[evolution-patches] patch to build eds against latest glib

[Larry Reaves <larry yrral net>]

There was a glib commit (git.gnome.org/glib
4c791f49e58688d1b8948d083c1780cab9d26e93) on the 18th that adds
reference counting to GMappedFile, and deprecates g_mapped_file_free,
replacing it with g_mapped_file_unref.  The attached patch replaces each
call to g_mapped_file_free with g_mapped_file unref.  Of course, eds
won't build with this patch without the very latest glib ;).
