The changes in this checkin were done by Sheng Peng in an effort
to run the gateway using a preemptive channel access callback context.
I have very little specific info on the testing other than to say we ran it
on several gateways for a few weeks.
There were a few anecdotal reports of better throughput, but we also
had it crash 5 times over 9 days and switched to using a gateway version
using non-preemptive ca with file descriptors via USE_FDS.
This needs more work, possibly changing to using the multi-threaded CA
server, as the only multi-threaded portion of this version is the CA client side
which spawns two threads per connection. We probably need some mutex protection
in the callbacks as well to prevent crashes.
