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.

Amended test 1915 to verify.

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.

build: drop redundant HAVE_PTHREAD_H guard
Prior to this patch code used either `HAVE_PTHREAD_H`, or
`HAVE_THREADS_POSIX`, or both, to decide if POSIX Threads support is
present. In effect requiring both to be defined for a consistent build.

Drop detecting and guarding for `pthread.h`, and assume it present when
`HAVE_THREADS_POSIX` is set.

OS/400 had `HAVE_PTHREAD_H` set, but not `HAVE_THREADS_POSIX`, which
possibly left threading disabled in most sources.
