Multiple functions have been deprecated over the years, annotate them
with attribute deprecated.
When possible show a message about their replacements.
This is a continuation/completion of PR #706

This PR makes the c-ares parser introduced in 1.21, and the new writer, along with associated helpers public. These helpers are contained in a new public header of `ares_dns_record.h` which should _**not**_ be included directly, instead simply including `ares.h` is sufficient. This will address #587, as well as #470.
A follow-up PR will be made which will transform `adig` to use the new parsers and helpers.
This PR does not currently add man pages for these public functions, that will be in a follow-up PR once the `adig` migration is done which may expose additional needed helpers.
The two aforementioned PRs will be done before the 1.22 release.

The acountry utility required a third party DNSBL service from nerd.dk in order to operate. That service has been offline for about a year and there is no other comparable service offering. We are keeping the code in the repository as an example, but no longer building it.

All files have their licence and copyright information clearly
identifiable. If not in the file header, they are set separately in
.reuse/dep5.
All used license texts are provided in LICENSES/
As per RFC6761 Section 6.3, "localhost" lookups need to be special cased to return loopback addresses, and not forward queries to recursive dns servers.
We first look up via files (/etc/hosts or equivalent), and if that fails, we then attempt a system-specific address enumeration for loopback addresses (currently Windows-only), and finally fallback to ::1 and 127.0.0.1.

Fixes Bug: #399
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.

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.
