23f5d145ec 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.

ee1235a7cd Removed inclusion of <sys/types.h> in .c-files 
since it's already included through "setup.h".

ed7bff1fec Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and 
not always zero!

e5247ae65d Added ares_getsock() to extract sockets to wait for action on, without being 
limited to select().
