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. See GNOME commit: https://git.gnome.org/browse/gnome-common/commit/?id=493d55921f26ac3a9a3b7cc33756c88daace329e And follow up commits: https://git.gnome.org/browse/gnome-common/log/macros2/gnome-code-coverage.m4

+dnl **Based on GNOME's code coverage**
+dnl MATE_CODE_COVERAGE
+dnl
+dnl Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be
+dnl included in the CFLAGS and LIBS/LDFLAGS variables of every build target
+dnl (program or library) which should be built with code coverage support.
+dnl Also defines MATE_CODE_COVERAGE_RULES which should be substituted in your
+dnl Makefile; and $enable_code_coverage which can be used in subsequent
+dnl configure output.
+dnl
+dnl Note that all optimisation flags in CFLAGS must be disabled when code
+dnl coverage is enabled.
+dnl
+dnl Derived from Makefile.decl in GLib, originally licenced under LGPLv2.1+.
+dnl This file is licenced under LGPLv2.1+.
+dnl
+dnl Usage example:
+dnl configure.ac:
+dnl MATE_CODE_COVERAGE
+dnl
+dnl Makefile.am:
+dnl @MATE_CODE_COVERAGE_RULES@
+dnl my_program_LIBS = … $(CODE_COVERAGE_LDFLAGS) …
+dnl my_program_CFLAGS = … $(CODE_COVERAGE_CFLAGS) …
+dnl
+dnl This results in a “check-code-coverage” rule being added to any Makefile.am
+dnl which includes “@MATE_CODE_COVERAGE_RULES@” (assuming the module has been
+dnl configured with --enable-code-coverage). Running `make check-code-coverage`
+dnl in that directory will run the module’s test suite (`make check`) and build
+dnl a code coverage report detailing the code which was touched, then print the
+dnl URI for the report.
