Sam Spilsbury b42fb52537 Added tests for the vertex clipping code.
This tests (via the table-driven testing method) that the correct
number of vertices and also the correct vertices themselves
are generated for an clip box and polygon of up to eight vertices.

Also add a libshared-test.la so that we don't have to build weston-test-runner
all the time
