Issue #1274 - Part 1: Adopt the cairo version as our own.

- Move header licensing from tri-license to MPL 2.0. MPL-compatible
  other licensing has been retained where originally present.
- Remove individual superseded licensing terms.
- Remove patches, outdated readmes & incomplete patch summaries.
- Remove incomplete cairo release notes (only went up to 1.6.4 anyway).
- Rewrite COPYING to indicate the current state of the library in tree.
