John Ericson 6910f5dcb6 Generate API docs with Doxygen
The motivation is as stated in issue #7814: even though the the C++ API
is internal and unstable, people still want it to be well documented for
sake of learning, code review, and other purposes that aren't predicated
on it being stable.

Fixes #7814
