failf() needs an easy handle to work. This change removes the call since
there is normnally nowhere to show the output if init fails.
Bonus: improve language in an infof() call

Necessary when the libssh2/libssh client library does not support KEX
algos offered by default by the OpenSSH server. E.g. libssh2 with WinCNG
combined with OpenSSH 10+.
Also: use this option in GHA/windows.

Several mbedTLS resources (entropy/CTR-DRBG, CA/client certs, keys, CRL)
are initialized and may allocate memory before initialized is set, and
must still be cleaned up.

Closes#21440
So that CURLcode failure is correct and not figured out later via
`conn->bits.proxy`. Add the flag to the async struct.
`for_proxy` is figured out by the caller of Curl_resolv() when it
figures out which host/proxy name it wants the addresses for.
Remove CONN_IS_PROXIED macro as no longer needed.
Closes#21423
Before this fix, Curl_tls_keylog_open() assigned the environment
variable result to a global keylog_file_name without freeing any prior
allocation. If the file cannot be opened (e.g., permission error)
keylog_file_fp stays NULL, so subsequent calls to Curl_tls_keylog_open
will overwrite keylog_file_name and leak the previous allocation.

Closes#21427
Since we have a new struct instance for each async operation now and
async operation may happen in parallel, remove the connection bit
indicating doh is in progress.
Closes#21422
When trying to connect a pending transfer, remember the `mid` that was
last reactivated and start looking for future pending handles from the
last one forward through the pending bitset.
Background: when many pending handles exist, iterating the bitset always
from the start may become unfair to transfers that were assigned higher
`mid` values.
Fixes#21396

Closes#21412
- unify the query and fragment separator logic
- read the bitflags directly instead of via a temp variable
- narrow the scope of a few variables
Closes#21417
Due to year-long unreliability.
The default Ubuntu mirror works as fast as the Azure one when it's
working at its normal speed. And has HTTPS.
Also:
- replac the retry hack that turn out to not solve the problem.
- add timeouts to each download step to catch slowness early.

GitHub runners are getting new 3rd-party sources frequntly now, last
week `docker.list`, this week: `google-chrome.sources`. To avoid
playing catch up, allowlist the only one we use: `ubuntu.sources`. If
this is renamed, CI would break. Let's hope this happens much less
often than new sources.

When starting an c-ares query, the provided callback may be invoked
right away, leading to a decrement of `queries_ongoing`. Increment
the counter *before* call c-ares. Otherwise, the `async->done` bit
is not properly set.

As 'flags' may already have been set to something when
parse_conversion() is called, make sure to only OR the new flags.

- introduce 'struct when' to hold the parser result
- initwhen() initializes a 'struct when'
- datestring() parses strings
- datenum() parses numbers
- datecheck() does some final checks
- tzadjust() adds the time zone offset
- convert math to 64 bit, squeeze into time_t only in the last step,
mktimet() does the time_t storing

libcurl now waits 50ms for AAAA and HTTPS results (when requested) to
return before continuing with the connect.
Added HTTPS-RR to the "was resolved" information info message. Changed
logging of HTTPS-RR to a one-liner with RFC 9460 like formatting. This
way the user can see if/what was resolved and used in connecting.
