FIXES 17805

I've been stress testing a patch all weekend that changes the way
thread-local packet quotas are computed.  I was able to replicate the
unbounded packet alloc problem on unix server components by eliminating my
code from rxi_StartServerProcs that sets the maximum number of expected
threads.  This patch makes the upper thread limit get computed on the fly,
adds some thread-local free packet queue statistics, and a few other minor
tweaks.  I still don't have a working windows development environment, so
I can't say whether this will fix all the windows client problems.  But,
the unbounded packet allocation problem should go away with this patch.

stress testing on windows succeeds as well. <jaltman@secure-endpoints.com>
