Add copyright notices. The tool interface sucks (especially "committing" information, which is just me doing everything by hand from the command line), but I think this is in theory actually a viable way of describing the world. So copyright it.

#include "cache.h"
Use blob_, commit_, tag_, and tree_type throughout. This replaces occurences of "blob", "commit", "tag", and "tree", where they're really used as type specifiers, which we already have defined global constants for.

#include "tree.h"
Update write-tree to use cache-tree. The updated write-tree reads from $GIT_DIR/index.aux to pick up subtree objects information, updates the cache-tree with the index, and updates index.aux file after writing a tree out of the index file. Until update-index and other programs that modify the index are updated to maintain index.aux file, the index.aux file written by the last write-tree will become stale immediately after they update the index, which will result in the whole tree recomputation just like the original write-tree. The idea is to convert those commands to invalidate cache-tree whenever they touch the index entries, and write updated index.aux out. After the index is updated with them, write-tree will be able to reuse the parts of the cache-tree that have not been touched. Signed-off-by: Junio C Hamano <junkio@cox.net>

This implements the new "recursive tree" write-tree. It's got some debugging printouts etc still in it, but testing on the kernel seems to show that it does indeed fix the issue with huge tree files for each commit.
