As per #487, documentation states the port should be in network byte
order, but we can see from the test cases using MockServers on
different ports that this is not the case, it is definitely in host
byte order.

To make them render "nicer" in both terminals and on the website.
- Removes the bold
- Removes .PP lines
- Indents them more like proper code style

There was a lot of windows initialization code specific to the era that predates Windows Vista such as reading DNS configuration from the registry, and dynamically loading libraries to get access to functions that didn't exist in XP or earlier releases.
Vista was released in January 2007, and was EOL'd in 2017, and support for Vista is still maintained with this patch set.
XP was EOL'd in Apr 8 2014.
I believe the last OS based on something earlier than Vista was POSReady 2009, as it was XP based for some reason, and that was EOL'd in January 2019. Considering any POS system falls under the PCI-DSS rules, they aren't allow to run POSReady 2009 any more so there is no reason to try to continue supporting such systems.
We have also targeted with our build system Vista support for the last few years, and while developers could change the target, we haven't had any reports that they have.
ares_gethostbyname() and ares_getaddrinfo() do a lot of similar things, however ares_getaddrinfo() has some desirable behaviors that should be imported into ares_gethostbyname(). For one, it sorts the address lists for the most likely to succeed based on the current system routes. Next, when AF_UNSPEC is specified, it properly handles search lists instead of first searching all of AF_INET6 then AF_INET, since ares_gethostbyname() searches in parallel. Therefore, this PR should also resolve the issues attempted in #94.
A few things this PR does:
1. ares_parse_a_reply() and ares_parse_aaaa_reply() had very similar code to translate struct ares_addrinfo into a struct hostent as well as into struct ares_addrttl/ares_addr6ttl this has been split out into helper functions of ares__addrinfo2hostent() and ares__addrinfo2addrttl() to prevent this duplicative code.
2. ares_getaddrinfo() was apparently never honoring HOSTALIASES, and this was discovered once ares_gethostbyname() was turned into a wrapper, the affected test cases started failing.
3. A slight API modification to save the query hostname into struct ares_addrinfo as the last element of name. Since this is the last element, and all user-level instances of struct ares_addrinfo are allocated internally by c-ares, this is not an ABI-breaking change nor would it impact any API compatibility. This was needed since struct hostent has an h_name element.
4. Test Framework: MockServer tests via TCP would fail if more than 1 request was received at a time which is common when ares_getaddrinfo() queries for both A and AAAA records simultaneously. Infact, this was a long standing issue in which the ares_getaddrinfo() test were bypassing TCP alltogether. This has been corrected, the message is now processed in a loop.
5. Some tests had to be updated for overall correctness as they were invalid but somehow passing prior to this change.

CAA (Certification Authority Authorization) was introduced in RFC 6844.
This has been obsoleted by RFC 8659. This commit added the possibility
to query CAA resource records with adig and adds a parser for CAA
records, that can be used in conjunction with ares_query(3).
Closes Bug: #292

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.
