Robert Bragg 603f936745 Bug 1162 - Re-works the tests/ to use the glib-2.16 unit testing 
framework

	* configure.ac:
	* tests/*:
	The tests have been reorganised into different categories: conformance,
	interactive and micro benchmarks.
	- conformance tests can be run as part of automated tests
	- interactive tests are basically all the existing tests
	- micro benchmarks focus on a single performance metric

	I converted the timeline tests to conformance tests and also added some
	tests from Neil Roberts and Ebassi.

	Note: currently only the conformance tests use the glib test APIs,
	though the micro benchmarks should too.

	The other change is to make the unit tests link into monolithic binaries
	which makes the build time for unit tests considerably faster. To deal
	with the extra complexity this adds to debugging individual tests I
	have added some sugar to the makefiles so all the tests can be run
	directly via a symlink and when an individual test is run this way,
	then a note is printed to the terminal explaining exactly how that test
	may be debugged using GDB.

	There is a convenience make rule: 'make test-report', that will run all
	the conformance tests and hopefully even open the results in your web
	browser. It skips some of the slower timeline tests, but you can run
	those using 'make full-report'
