Implements temporary breakpoints, ignore counts, disabling and
(re)-enabling, and conditionals.
Breakpoints are indexed by number through bpbynumber and by
the file,line tuple using bplist. The former points to a
single instance of class Breakpoint. The latter points to a
list of such instances since there may be more than one
breakpoint per line.
