This commit gets rid of libc's abort() usage in the test suite using
test asserts instead.
Asserts run in the server as plugins aren't converted because they are
shared between server and client.

We're pushing more and more mutable state into paint nodes, but this state
has a non-zero cost to rebuild every render.
Let's take care to track when we need to rebuild the state.

Add an output transform function that doesn't use matrices so we can
test our matrix generation by applying it to vectors and comparing with
the non-matrix variant.

Add tests to validate that weston_matrix_to_transform() works properly
on the matrices generated by weston_surface_build_buffer_matrix() and
weston_output_update_matrix()

When we build up a matrix from a series of operations, it's very useful
to know if the combined operations still result in something that matches
a wl_output_transform.
This adds a function to test if a matrix leads to a standard output
transform, and returns the transform if it does.
Tests are provided that check if complex series of operations return
expected results - the weston_matrix_needs_filtering function is tested
at the same time.
