[cairo] [PATCH cairo v2 0/8] Coverity fixes

[Uli Schlachter]

Patches 1, 3, 4, 5, 7, and 8 (well, and 2) are

Reviewed-By: Uli Schlachter <psychon at znc.in>

I ran into a mental timeout when staring at Patch 6, so I skipped that
one (for now?).

I have one remaining question: The test suite is happy with this and
doesn't hit the new assertions, right?

Cheers,
Uli
