* Service support has been added to getaddrinfo.
* ares_parse_a/aaaa_record now share code with the addrinfo parser.
* Private ares_addrinfo structure with useful extensions such as ttls (including cname ttls),
as well as the ability to list multiple cnames in chain of lookups

Due to an order of incrementing the remaining queries and calling ares_query, on a bad domain
the registered callback wouldn't be called.
Bug: #248
Fixed-By: @kedixa
There are two possible causes for infinite loops fo NXDOMAIN, based on how many dots are in the domain name (one for < ARES_OPT_NDOTS and one for >= ARES_OPT_NDOTS), where it will repeat the same query over and over as the hquery->next_domain doesn't increment.

This is a port of RFC 6724 compliant sorting function from Android Bionic project:
e919b116d3/libc/netbsd/net/getaddrinfo.c
The latest version is essentially the same, except two additional parameters to test connection with (mark/uid):
https://android.googlesource.com/platform/bionic/+/master/libc/dns/net/getaddrinfo.c
Please note that even that version has some restrictions. It doesn't support some rules from RFC 6724:
Rule 3 (Avoid deprecated addresses)
Rule 4 (Prefer home addresses)
Rule 7 (Prefer native transport)

This PullRequest fixes a bug in the function add_to_addrinfo which task is to add new addrinfo items to the ai_next linked list. Also additional unit tests for testing ares_getaddrinfo will be added:
Additional mock server test classes (ares-test-mock-ai.cc):
MockTCPChannelTestAI
MockExtraOptsTestAI
MockNoCheckRespChannelTestAI
MockEDNSChannelTestAI
RotateMultiMockTestAI
NoRotateMultiMockTestAI
Additional live tests (ares-test-live-ai.cc):
LiveGetHostByNameV4
LiveGetHostByNameV6
LiveGetHostByNameV4AndV6

Initial implementation for ares_getaddrinfo(). It is NOT compliant with RFC6724, though
it is expected to come closer to conformance prior to the next release.
Features not supported include sorted addresses and honoring of service and hints
parameters.
