The only caller has been changed to treat a NULL tree as a special
case and use the existing git_tree_entry_byindex.

This function is already implemented (better) as git_index_get. Change
the only caller to use that function.

1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.
It's not obvious that recurse_tree_entries or recurse_tree_entry
should free a resource that wasn't allocated by them. Do this
explicitely and plug a leak while we're at it.

The `hashfile` function has been moved to ODB, next to `git_odb_hash`.
Global state has been removed from the dirent call in `status.c`,
because global state is killing the rainforest and causing global
warming.
Add git_status_hashfile() to get blob's object id for a file without adding
it to the object database or needing a repository at all.
This functionality is similar to `git hash-object` without '-w'.
