Also:
- check `curl_url()` for NULL where missing.
- free memory `curl_url_get()` return pointer where missing.
- propagate `curl_url_set()` errors in `clear_url()`, where missing.
- add missing NULL-check before `strcmp()` in `clear_url()`.

- H3 proxy: re-sync code with original source `curl_ngtcp2.c` to reduce
differences, and to apply missed minor fixes. Also apply clang-format.
Drop redundant `#undef`s, casts, `#endif` comments, includes, drop
intermediate variables, sync include and macro order.

- tests/http/env: rename `tcpdmp` to `tcpdump` to match object variable.
- mbedtls: drop incorrect `mbedTLS 4+` comments.
(features are also supported by 3+, meaning it's always supported.)
- lib1648: rename a variable to match purpose.
- CIPHERS.md: alpha-sort link list.
- replace rare `X''` hex markup with `0x`.

When a proxy is set from an environment variable, detect if that proxy
is not the same as previously and flush state.

Closes#21666
When using `-D_CURL_TESTS_CONCAT=ON` with CMake, do not concatenate
`first.h` (or any future header) into the output C file, but `#include`
it instead. This is to play nice with compilers and analyzers which may
apply different checker rules on logic found in headers, vs. the input
source file. As seen for example with `-Wunused-macro` enabled in CI.
After this patch concatenated sources behave closer to regular C
sources.
Also:
- first.h: drop some `-Wunused-macro` silencers that became redundant
with this patch.

Prior to this patch the test was always skipped due to failing precheck
with `CURLE_BAD_FUNCTION_ARGUMENT`, because of the zero-length blob
passed to setopt. Fix by passing a non-zero long dummy blob as done in
`mk-lib1521.pl`.
Fixing:
```
test 0678 SKIPPED: CURLOPT_CAINFO_BLOB is not supported
```

Also fix fallouts found.
Windows clang-tidy CI job is a little pickier than I'd prefer due to the
`_CURL_TESTS_CONCAT=ON` option used there, and all macros considered
local, thus checked by the compiler. Upside: it revealed macro usage
dynamics in tests. If too annoying, `first.h` may be opted-out from the
concat logic. Some macros may also be deleted instead of `#if 0`-ing.

If the hostname is specified as an IPv4 numerical address and it is
followed by a single dot, acccept that as a valid IPv4 and remove the
dot when normalizing.
This prevents otherwise legitimate IPv4 hostnames to have trailing dots.
Seems to match what browsers do.
Extended test 1560 to verify.
Closes#21635
Or consisting of just a single dot.
Such names cannot be resolved with DNS.
While they *can* still be resolved with /etc/hosts or --resolve tricks,
they easily cause internal problems because their trailing dots.
Let's not allow them anymore.
Closes#21622
Authorizdation credentials are kept in `struct Curl_creds`. This contains:
* `user`: the username, maybe the empty string
* `passwd`: the password, maybe the empty string
* `sasl_authzid`: the SASL authz value, maybe the empty string
* `oauth_bearer`: the OAUTH bearer token, maybe the empty string
* `source`: where the credentials from from
* `refcount`: a reference counter to link/unkink creds
A `creds` with all values empty is equivalent to NULL, e.g. no `creds`
instance. With reference counting, `creds` can be linked/unlinked
in several places.
See docs/internals/CREDENTIALS.md for use.
Closes#21548
- passing an unknown string to CURLOPT_ECH now returns error
To properly allow applications to spot if they pass in a typo or
something to libcurl.
- CURLECH_DISABLE is now a plain zero internally, not a dedicated bit which
simplifies checks for when ECH is enabled
- Dropped the CURLECH_CLA_CFG bit, and just check STRING_ECH_CONFIG
- Turn grease/enable/hard into three different numerical values, no bitmask
needed
- Convert the struct field 'tls_ech' from an int to a byte.

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.

- 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.
Closes#21175
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.
