[PATCH v3 00/14] Tidying up references code

[mhagger@alum.mit.edu]

From: Michael Haggerty <mhagger@alum.mit.edu>

I have re-rolled this patch series against gitster/master for your
merging enjoyment.

Original description of patch series:

This is the next installment of the reference changes that I have been
working on.  This batch includes a lot of tidying up in preparation
for the real changes.

The last few patches have a little bit of meat on them.  They start
changing the innards of refs.c to work less with strings and more with
objects.  This work will continue in later patches with the ultimate
goal of swapping the data structure used to store cached references
out from under the module--changing it from a sorted array of pointers
into a hierarchical tree shaped like the reference namespace tree.

Michael Haggerty (14):
  cache.h: add comments for git_path() and git_path_submodule()
  struct ref_entry: document name member
  refs: rename "refname" variables
  refs: rename parameters result -> sha1
  clear_ref_array(): rename from free_ref_array()
  is_refname_available(): remove the "quiet" argument
  parse_ref_line(): add docstring
  add_ref(): add docstring
  is_dup_ref(): extract function from sort_ref_array()
  refs: change signatures of get_packed_refs() and get_loose_refs()
  get_ref_dir(): change signature
  resolve_gitlink_ref(): improve docstring
  Pass a (ref_cache *) to the resolve_gitlink_*() helper functions
  resolve_gitlink_ref_recursive(): change to work with struct ref_cache
