Split CT_ExtractAndPatch in two: CT_Extract and CT_Patch:
- it is unworkable to have CT_ExtactAndPAtch cope with all those silly glibc addons:
- they can have 'short' (as 'ports') or 'long' (as glibc-ports-2.7) names
- patches are against eithe the short or long name, but non-uniformly use one or the other
- it is the reposibility of the component (glibc in this case) to handle corner cases such as those
- update all components to use the new functions
