[PATCH 00/35] refactoring refspecs

When working on protocol v2 I noticed that working with refspecs was a little difficult because of the various api's that existed. Some functions expected an array of "const char *" while others expected an array of "struct refspec". In all cases a length parameter needed to be passed as a parameter as well. This makes working with refspecs a little challenging because of the different expectations different parts of the code base have.

This series refactors how refspecs are handled through out the code base by renaming the existing struct refspec to refspec_item and introducing a new 'struct refspec' which is a container of refspec_items, much like how a pathspec contains pathspec_items. This simplifies many callers and makes handling pathspecs a bit easier.

I have some follow on work which I'll build on top of this series, but since this was already getting a bit lengthy at 35 patches I'll save that for another time.
