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>

write-tree: check extra arguments and die but be a bit more helpful. "git-write-tree junk" complains and dies, but it does not say what option it supports. Die with the usage string in such a case. Signed-off-by: Junio C Hamano <junkio@cox.net>

Make error messages from cherry-pick/revert more sensible The original "rewrite in C" did somewhat a sloppy job while stealing code from git-write-tree. The caller pretends as if the write_tree() function would return an error code and being able to issue a sensible error message itself, but write_tree() function just calls die() and never returns an error. Worse yet, the function claims that it was running git-write-tree (which is no longer true after cherry-pick stole it).

Provide git_config with a callback-data parameter git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.
