tests: Add performance tracking framework

Browse Source 
This adds a performance tracking framework that can run a set of tests over
specified git revisions. The ruby script for generating the reports comes from
similar performance tracking in GEGL. The framework permits evaluating new
tests against older version of clutter.

The tests themselves go through a few hoops for disabling framerate limiting in
both mesa and clutter.

When running make check the tests will be run and lines of the form:

@ test-state: 40.51 fps

will be left in the output, a script can scrape these lines out of a build log
on a buildbot to in other ways track performance.

@ -4,15 +4,15 @@ The conform/ tests should be non-interactive unit-tests that verify a single
feature is behaving as documented. See conform/ADDING_NEW_TESTS for more
details.
The micro-bench/ tests should be focused perfomance test, ideally testing a
single metric. Please never forget that these tests are synthetec and if you
are using them then you understand what metric is being tested. They probably
don't reflect any real world application loads and the intention is that you
use these tests once you have already determined the crux of your problem and
need focused feedback that your changes are indeed improving matters. There is
no exit status requirements for these tests, but they should give clear
feedback as to their performance. If the framerate is the feedback metric, then
the test should forcibly enable FPS debugging.
The performance/ tests are performance tests, both focused tests testing single
metrics and larger tests. These tests are used to report one or more
performance markers for the build of Clutter. Each performance marker is picked
up from the standard output of running the tests from strings having the form
"\n@ marker-name: 42.23" where 'marker-name' and '42.23' are the key/value pairs
of a single metric. Each test can provide multiple key/value pairs. Note that
if framerate is the feedback metric the test should forcibly enable FPS
debugging itself. The file test-common.h contains utility function helping to
do fps reporting.
The interactive/ tests are any tests whose status can not be determined without
a user looking at some visual output, or providing some manual input etc. This
