[PATCH 1/6] Add struct pathspec

This struct for now is just a wrapper for the current pathspec form: const char **. It is intended to be extended with more useful pathspec-related information over time.

The data structure for passing pathspec around remains const char **, struct pathspec will be initialized locally to be used and destroyed. Hopefully all pathspec related code will be gradually migrated to pass this struct instead.
