Now that there are no callers of 'parse_push_refspec()',
'parse_fetch_refspec()', and 'free_refspec()', remove these
functions.

Convert 'valid_fetch_refspec()' to use the new 'parse_refspec()'
function to only parse a single refspec and eliminate an allocation.

Introduce 'struct refspec', an abstraction around a collection of
'struct refspec_item's much like how 'struct pathspec' holds a
collection of 'struct pathspec_item's.
A refspec struct also contains an array of the original refspec strings
which will be used to facilitate the migration to using this new
abstraction throughout the code base.

Factor out the logic which parses a single refspec into its own
function. This makes it easier to reuse this logic in a future patch.

In preparation for introducing an abstraction around a collection of
refspecs (much like how a 'struct pathspec' is a collection of 'struct
pathspec_item's) rename the existing 'struct refspec' to 'struct
refspec_item'.

In preparation for performing a refactor on refspec related code, move
the refspec parsing logic into its own file.
