[MERGE] Deprecate compare_trees

[Robert Collins]

This patch deprecates compare_trees, moving its body to
InterTree.changes_from. At the same time, to facilitate code reuse, I
pulled up the lock_read, lock_write and unlock methods from
InterRepository to InterObject and documented in the docstring what
conditions they may be used under.

Cheers,
Rob
