Start moving unpack-trees to "struct tree_desc"
This doesn't actually change any real code, but it changes the interface to unpack_trees() to take an array of "struct tree_desc" entries, the same way the tree-walk.c functions do. The reason for this is that we would be much better off if we can do the tree-unpacking using the generic "traverse_trees()" functionality instead of having to the special "unpack" infrastructure. This really is a pretty minimal diff, just to change the calling convention. It passes all the tests, and looks sane. There were only two users of "unpack_trees()": builtin-read-tree and merge-recursive, and I tried to keep the changes minimal.
