[Mesa-dev] [PATCH mesa 2/2] mapi: add asserts to enforce ordering and uniqueness

[Eric Engestrom]

Dylan Baker recently added functions to that list and had to try a couple times
to avoid duplicates. He said [1] he ended up testing it using:
  len(functions) == len(set(functions))
which I thought should always be done.

Add this and a couple other tests using asserts to enforce the ordering and
uniqueness of the `functions` list, and the uniqueness and compactness of the
`offsets` dictionary.

If people don't like enforcing the order, I'm happy to drop the previous patch
and send a revised version of this patch with this last assert removed.
