[cogl] matrix-mesa: move to _cogl_matrix namespace

[Robert Bragg <rbragg src gnome org>]

commit ee237be28567d0bd6d23f90d0f852e675687c778
Author: Robert Bragg <robert linux intel com>
Date:   Thu Jun 30 20:33:50 2011 +0100

    matrix-mesa: move to _cogl_matrix namespace
    
    Instead of having everything in cogl-matrix-mesa.[ch] be in the
    _math namespace this now puts them in the _cogl_matrix namespace
    instead, in preparation for flattening cogl-matrix-mesa.[ch] into
    cogl-matrix.[ch].
