* Reduce data copying in Broker message processing (Jon Siwek, Corelight)
* Improve Broker I/O loop integration: less mutex locking (Jon Siwek, Corelight)
Checking a subscriber for available messages required locking a mutex,
but we should never actually need to do that in the main-loop to check
for Broker readiness since we can rely on file descriptor polling.
* Improve processing of broker data store responses (Jon Siwek, Corelight)
Now retrieves and processes all N available responses at once instead
of one-by-one-until-empty.

* RDP: Add parsing and logging of channels requested by the client. (Vlad Grigorescu)
