fsmonitor: add new watchman notifications to fsmonitor extension
The fsmonitor extension currently sends state-enter and state-leave
notifications to watchman on the update operation. This commit creates
additional notifications for the following events :
- transaction creation and commit/abort. A state-enter notification will be
sent when a transaction is created. It will provide the working copy
parent's hash. A state-leave notification will be sent when the
transaction is committed or aborted. It will provide the working copy
parent's hash.
- calls to set-parent will cause state-enter and state-leave notifications
to be sent. The state-enter notification will be sent prior to the
set-parent operation and the working copy parent's hash will be provided at
this time. The state-leave notification will be sent after the set-parent
operation completes providing the working copy parents hash.
Test Plan:
tested on dev server to check that necessary notifications were sent/received
