Review request for Plasma.


Summary
-------

We make a thread-local copy of the SearchContext for each Runner. As such, there is no need to do locking on the thread-local copy. This patch also adds assertions on the non-thread safe methods (e.g. addExactMatch) which are used from thread-local copies, but which should never be used in the shared version.
