Subject: tree/diff header cleanup.
X-Git-Tag: v1.3.0-rc2~28
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/1b0c7174a17de801051402ed35ac085ebd91e88c?ds=inline;hp=1b0c7174a17de801051402ed35ac085ebd91e88c

tree/diff header cleanup.

Introduce tree-walk.[ch] and move "struct tree_desc" and
associated functions from various places.

Rename DIFF_FILE_CANON_MODE(mode) macro to canon_mode(mode) and
move it to cache.h.  This macro returns the canonicalized
st_mode value in the host byte order for files, symlinks and
directories -- to be compared with a tree_desc entry.
create_ce_mode(mode) in cache.h is similar but is intended to be
used for index entries (so it does not work for directories) and
returns the value in the network byte order.
