Documentation generation fixes.

- Fix many instances of incorrect and incomplete doxygen annotations.
- Teach doxygen not to complain when it comes accross gcc __attribute__
specifications.
- Turn off graph generation by default.
- Make doxygen quiet, so we can actually see warnings when they occur.
