store tcp/udp port names in epan scope
This causes them to be freed on shutdown, cleaning up ~800KB of "reachable"
memory according to valgrind. The fact that we even need to construct these
as
value_strings is questionable IMHO, but that's a problem for a later date.
Switch epan_scope to the BLOCK allocator now that we're using it for so
much
more, this gives a small but measurable increase in startup time.
