Subject: [PATCH 1/7] prune_remote(): exit early if there are no stale
 references

Aside from making the logic clearer, this avoids a call to
warn_dangling_symrefs(), which always does a for_each_rawref()
iteration.

Also free them together at the end of the function.

In a moment, the array version will become redundant. Managing them
together makes later steps more obvious.

Subject: [PATCH 3/7] prune_remote(): sort delete_refs_list references en masse

Inserting items into a list in sorted order is O(N^2) whereas
appending them unsorted and then sorting the list all at once is
O(N lg N).

string_list_insert() also removes duplicates, and this change loses
that functionality. But the strings in this list, which ultimately
come from a for_each_ref() iteration, cannot contain duplicates.

Subject: [PATCH 4/7] repack_without_refs(): make the refnames argument a
 string_list

Most of the callers have string_lists available already, whereas two
of them had to read data out of a string_list into an array of strings
just to call this function. So change repack_without_refs() to take
the list of refnames to omit as a string_list, and change the callers
accordingly.
