Merge branch 'bc/tree-walk-oid'

The code to walk tree objects has been taught that we may be
working with object names that are not computed with SHA-1.

* bc/tree-walk-oid:
  cache: make oidcpy always copy GIT_MAX_RAWSZ bytes
  tree-walk: store object_id in a separate member
  match-trees: use hashcpy to splice trees
  match-trees: compute buffer offset correctly when splicing
  tree-walk: copy object ID before use
