fsmonitor: remove watchman transaction and working copy change notifications Remove working copy change and transaction notifications. We were relying upon callbacks on transaction function. This caused issues with lock ordering. A different approach will be adopted in a subsequent commit. Differential Revision: https://phab.mercurial-scm.org/D1611

patch: catch unexpected case in _inlinediff If operation is neither 'diff.inserted' or 'diff.deleted', label and token won't be define. This patch explicitely catches that exception.

patch: reverse _inlinediff output for consistency
