Limit the number of DNS message processed from a single TCP read
The single TCP read can create as much as 64k divided by the minimum
size of the DNS message.  This can clog the processing thread and trash
the memory allocator because we need to do as much as ~20k allocations in
a single UV loop tick.

Limit the number of the DNS messages processed in a single UV loop tick
to just single DNS message and limit the number of the outstanding DNS
messages back to 23.  This effectively limits the number of pipelined
DNS messages to that number (this is the limit we already had before).

This reverts commit 780a89012d.
