Avoid buffer overflow in RC4 loop comparison (#336) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)

Configuration option to limit number of UDP queries per ephemeral port (#549) Add a new ARES_OPT_UDP_MAX_QUERIES option with udp_max_queries parameter that can be passed to ares_init_options(). This value defaults to 0 (unlimited) to maintain existing compatibility, any positive number will cause new UDP ephemeral ports to be created once the threshold is reached, we'll call these 'connections' even though its technically wrong for UDP. Implementation Details: * Each server entry in a channel now has a linked-list of connections/ports for udp and tcp. The first connection in the list is the one most likely to be eligible to accept new queries. * Queries are now tracked by connection rather than by server. * Every time a query is detached from a connection, the connection that it was attached to will be checked to see if it needs to be cleaned up. * Insertion, lookup, and searching for connections has been implemented as O(1) complexity so the number of connections will not impact performance. * Remove is_broken from the server, it appears it would be set and immediately unset, so must have been invalidated via a prior patch. A future patch should probably track consecutive server errors and de-prioritize such servers. The code right now will always try servers in the order of configuration, so a bad server in the list will always be tried and may rely on timeout logic to try the next. * Various other cleanups to remove code duplication and for clarification.

# Travis on MacOS uses CloudFlare's DNS (1.1.1.1/1.0.0.1) which rejects ANY requests.
# Also, LiveSearchTXT is known to fail on Cirrus-CI on some MacOS hosts, we don't get
# a truncated UDP response so we never follow up with TCP.

Reorganize source tree (#349) Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of. Fix By: Brad House (@bradh352)
