git_tree_entry_byid

Lookup a tree entry by SHA value.

This returns a git_tree_entry that is owned by the git_tree. You don't have to free it, but you must not use it after the git_tree is released.

Warning: this must examine every entry in the tree, so it is not fast.

@param tree a previously loaded tree. @param id the sha being looked for @return the tree entry; null if not found
