advance_tcp_send_queue: avoid NULL ptr dereference
...
If given a too large 'num_bytes' value, it would cause a NULL ptr
dereference. Instead the code will now break out of the loop at the end
of the list.

sock-addr-storage: Detect and deal with lack of .ss_family member.
...
AIX, at least, does not have sockaddr_storage.ss_family member.
Detect this in the configure logic and use proper #ifdefs in the
ares_process logic.

Previously, processing a large batch of timeouts was O(n^2) in the number of
...
outstanding queries, and processing a DNS response packet was O(n) in the
number of outstanding queries. To speed things up in Google, we added a few circular,
doubly-linked lists of queries that are hash-bucketed based on
the attributes we care about, so most important operations are now O(1).
It might be that the number of buckets are higher than most people would need,
but on a quick calculation it should only be 100kB or so even on a 64-bit
system, so I've let it stay as-is.
