doxygen: various fixes in core/timer.h

Move a longish comment to the timer group so that it appears in the API doc.

Un-doxygen some floating comments that were associated with unrelated code
items ('/**' --> '/*').

Add braces to some function names so that the API doc will render as reference
links.
