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 - Remove individual superseded licensing terms. - Remove patches, outdated readmes & incomplete patch summaries.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.
