Patrick Steinhardt 235ac3f81a refspec: remove global tag refspec structure
We have a global tag refspec structure that is used by both git-clone(1)
and git-fetch(1). Initialization of the structure will break once we
enable `-Wwrite-strings`, even though the breakage is harmless. While we
could just add casts, the structure isn't really required in the first
place as we can simply initialize the structures at the respective
callsites.

Refactor the code accordingly.

/**
* A struct refspec_item holds the parsed interpretation of a refspec. If it
* will force updates (starts with a '+'), force is true. If it is a pattern
* (sides end with '*') pattern is true. If it is a negative refspec, (starts
* with '^'), negative is true. src and dest are the two sides (including '*'
* characters if present); if there is only one side, it is src, and dst is
* NULL; if sides exist but are empty (i.e., the refspec either starts or ends
* with ':'), the corresponding side is "".
*
* remote_find_tracking(), given a remote and a struct refspec_item with either src
* or dst filled out, will fill out the other such that the result is in the
* "fetch" specification for the remote (note that this evaluates patterns and
* returns a single result).
