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.

Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends while queued for transmission, note broken servers and close them in the main loop, and store TCP socket generation number in order not to send the same query twice over the same socket.

Brad House provided a fix for ares_save_options(): Apparently I overlooked
...
something with the ares_save_options() where it would try to do a malloc(0)
when no options of that type needed to be saved. On most platforms, this was
fine because malloc(0) doesn't actually return NULL, but on AIX it does, so
ares_save_options would return ARES_ENOMEM.

- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
...
(ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
by hand or disconnect the network cable in Windows 2000 or Windows XP, my
application gets 127.0.0.1 as the only name server. The problem comes from
'GetNetworkParams' function, that returns the empty string "" as the only
name server in that case. Moreover, the Windows implementation of
inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
