[PATCH xrandr-utils 4/6] Add unit test suite and a basic test of the geometry structs.

[Bryce Harrington]

This follows the style of the X server test suite, using autoconf's
built-in support for make check using asserts.

The first test trivially checks the geometry structures.

+This suite contains a set of tests to verify the behavior of the
+XrandrUtils API.  This suite follows the conventions of the X server
+test suite.

+= How to run the tests =
+Run "make check" in the test directory.  This will compile the tests and
+execute them in the order specified by the TESTS variable in
+test/Makefile.am.

+== Adding a new test ==
+When adding a new test, ensure that you add a short description of what
+the test does and what the expected outcome is.
