mozcontainer.c patch

These are mostly changes involving accessor methods that could be made to the
existing mozcontainer.c (and used in both GTK+ 2 and 3 builds) with the help
of gtk2compat.h.

There are only 2 or 3 statements that need to be different, and these could be
handled through preprocessor conditionals.

It should be fine to use the "allocation" variable here instead of using get_allocation to fetch the value just set. (I don't imagine calling size_allocate on children will change the parent's allocation.)
