Introduce catchpoint class

This introduces a catchpoint class that is used as the base class for
all catchpoints.  init_catchpoint is rewritten to be a constructor
instead.

This changes the hierarchy a little -- some catchpoints now inherit
from base_breakpoint whereas previously they did not.  This isn't a
problem, as long as re_set is redefined in catchpoint.
