Add a new breakpoint type "break by source regular expression".

Fix the RegularExpression class so it has a real copy constructor.
Fix the breakpoint setting with multiple shared libraries so it makes
  one breakpoint not one per shared library.
Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.)
