[0/5] libtirpc patches

While running valgrind on various nfs-utils programs, I came across a leak
while destroying a svc_dg object.

Second, I noticed that pollfds were being reallocated a dozen times, so
added an optimization to batch the allocations.

Third, I added destructor functions to clear up some of the static allocations
on exit. This is mainly to help with running valgrind. Not too important, more
of an RFC if it's desired.

Forth, I noticed that the comments expected the main thread to use the static
variable, instead of thread specific data but wasn't doing that. The last two
patches implement that. Also helps with valgrind as TSD is not destroyed on
the main thread.

Thanks,
Doug
