haproxy: use correct ip version on client supplied address
When a user supplies an IP address to use for the HAPROXY protocol,
the IP version reported must be deduced from the address and has
no relation to the IP version used for the upstream connection.

dnsd: implement HTTPS-RR with alpn pref and no-default-alpn
Support HTTPS records in dnsd that have ALPN preferences.

Add pytest test_22_* to verify that HTTPS record ALPN
preferencces take effect if the HTTPS resolve arrives in time.

Fix HTTPS eyeballing use of timeouts for second attempt. Also,
make an initial HTTP/1.1 attempt switch off HTTP/2.

unittests: cleanups
- make sure all UNITTEST prototypes mark in which unit test they are used,
  with "@unittest" markup

- make sure all UNITTEST functions do not use Curl_ prefix, as that is a
  prefix we use for global private functions and these functions are static
  and therefore not global and the prefix is wrong

- drop UNITTEST for functions not used in unit tests

- make the extract-unit-protos script highlight the above issues if found

- extract-unit-protos now also outputs the unit test number for all the
  generated protos in lib/unitprotos.h to aid readers. It also adds the source
  file and line number where the proto originates from.

- extract-unit-protos now exits with a non-zero value if any of the above
  warnings are triggered

- cf-dns: Curl_cf_dns_result => static cf_dns_result
- hostip: Curl_ipv6works => static ipv6works
- url: remove Curl_setup_conn() - not used anymore
- connect: Curl_timeleft_now_ms => UNITTEST timeleft_now_ms

hostip: resolve user supplied ip addresses
When a user supplied an ip address in a URL as hostname, use that even
when address family restrictions like -4 or -6 are set.

Add test_10_15/16 to verify with a local proxy server.

Fixes #21146
Reported-by: Terrance Wong

How:
- cf-dns: on see the hostname is an ip(v6) address, add the respective
  A/AAAA to the dns query bits
- cf-dns/hostip: only hand out addrinfos for a family if that family
  is part of the DNS queries. That prevents for example ipv6 addresses
  to show up from dns cache entries
- change cf-ip-happy to no longer check for "ip_version" and instead
  use all addresses that cf-dns hands out

cf-ip-happy: limit concurrent attempts
Introduce a limit on the concurrent connect attempts of 6:

- document this in CURLOPT_HAPPY_EYEBALLS_TIMEOUT_MS
- close the oldest attempt before opening a new one that would
  exceed the limit
- closing failed attempts early to avoid sockets use beyong their
  usefulness
- add tests for limits in unit2600

These changes are externally visible as file descriptors will be
reassigned where we previously kept the old one around and started a
new socket, allocating always a new descriptor.

hsts: make the HSTS read callback handle name dupes
Now the logic for handling name duplicates and picking the longest
expiry and strictest subdomain is the same for the callback as for when
reading from file.

Also strip trailing dots from the hostname added by the callback.

A minor side-effect is that the hostname provided by the callback can
now enable subdomains by starting the name with a dot, but we discourage
using such hostnames in documentation.

lib: make resolving HTTPS DNS records reliable:
- allow to specify when they are wanted on starting a resolve
- match dns cache entries accordingly. An entry which never
  tried to get HTTPS-RRs is no answer for a resolve that wants
  it.
- fix late arrivals of resolve answers to match the "async"
  records that started them - if it still exists.
- provide for multiple "async" resolves in a transfer at the
  same time. We may need to resolve an IP interface while the
  main connection resolve has not finished yet.
- allow lookup of HTTPS-RR information as soon as it is
  available, even if A/AAAA queries are still ongoing.

For this, the "async" infrastructure is changed:

- Defined bits for DNS queries `CURL_DNSQ_A`, `CURL_DNSQ_AAAA`
  and `CURL_DNSQ_HTTPS`. These replace `ip_version` which says
  nothing about HTTPS.
  Use them in dns cache entries for matching.
- enhance the `async->id` to be a unique `uint32_t` for
  resolves inside one multi. This is weak, as the id may
  wrap around. However it is combined with the `mid` of
  the easy handle, making collisions highly unlikely.
  `data->state.async` is only accessed in few places where
  the mid/async-id match is performed.
- vtls: for ECH supporting TLS backends (openssl, rustls, wolfssl),
  retrieve the HTTPS-RR information from the dns connection filter.
  Delay the connect if the HTTPS-RR is needed, but has not
  been resolved yet.

The implementation of all this is complete for the threaded
resolver. c-ares resolver and DoH do not take advantage of
all new async features yet. To be done in separate PRs.

Details:

c-ares: cleanup settings and initialisation. Any ares channel
is only being created on starting a resolve and propagating
operations in setopt.c to the channel are not helpful.

Changed threaded+ares pollset handling so that they do not
overwrite each others `ASYNC_NAME` timeouts.

Add trace name 'threads' for tracing thread queue and
pool used by threaded resolver.
