Add code coverage support

Add a MATE_CODE_COVERAGE m4 macro to allow projects to easily add
code
coverage support using lcov. This is heavily based on the code coverage
tooling from GLib (LGPLv2.1+), originally written by Patrick Hulin and
modified by Matthias Clasen, Stef Walter and Simon McVittie since.
Adapted for use in MATE by Sander Sweers.
