Merge branch 'lt/refs' into jc/for-each-ref-with-lt-refs
* lt/refs: (58 commits)
git-pack-refs --prune
pack-refs: do not pack symbolic refs.
Tell between packed, unpacked and symbolic refs.
Add callback data to for_each_ref() family.
symbolit-ref: fix resolve_ref conversion.
Fix broken sha1 locking
fsck-objects: adjust to resolve_ref() clean-up.
gitignore: git-pack-refs is a generated file.
wt-status: use simplified resolve_ref to find current branch
Fix t1400-update-ref test minimally
Enable the packed refs file format
Make ref resolution saner
Add support for negative refs
Start handling references internally as a sorted in-memory list
gitweb fix validating pg (page) parameter
git-repack(1): document --window and --depth
git-apply(1): document --unidiff-zero
gitweb: fix warnings in PATH_INFO code and add export_ok/strict_export
upload-archive: monitor child communication even more carefully.
gitweb: export options
