function init_id_key() under low memory conditions.

Added test case 1008 to verify. Note that #47 is still there.

attempt to force smaller bits to get read by clients.

it gets passed the initial value as an argument.

supported range.

in as argument!

target called 'filecheck' so that if you run 'make filecheck' in this directory
it'll check if the local files are also mentioned in the Makefile.am so that
they are properly included in release archives!

function do wrong on all input bytes that are >= 0x80 (decimal 128) due to a
signed / unsigned mistake in the code. I fixed it and added test case 543 to
verify.

previous proto struct was kept.

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.

Read and process as many packets as possible in read_udp_packets, to avoid having to run the entire event loop once per packet. (Patch from the Google tree.)

There are two different places in write_tcp_data() that advance the send_queue; however, they are slightly different and only the first one properly uses a while loop. Consolidate both into a single function that DTTR. (Patch from the Google tree.)

Reject names that are longer than 255 characters, to avoid problems with strict or buggy DNS server implementations. (Patch from the Google tree)

In ares_mkquery, make sure we set buflen and buf to reasonable values if there's an error. (Patch from the Google tree)

notifier callback(s).
