When a socket is closed, only inform the application
socket callback about it if the socket had been announced
before to the callback.

To fix test 1308 in MultiSSL builds.
Failure was caused by the random number generator virtual function being
NULL, instead of pointing to the implementation in the runtime-selected
TLS backend. This could happen in MultiSSL builds when a functionality
was asking for a random number without triggering a VTLS function table
initialization first. Such functionality is MIME, or form data via MIME.
The reason CI did not catch it in an earlier MultiSSL GHA/windows job,
is that it was a debug-enabled one. In debug-enabled builds the test
runner was overriding the random number generator for all tests.
Fixed this by moving the override to the tests requiring it, via
1fcf22585f#17971, enabling debug builds
to catch this issue.
Enable MultiSSL in two CI jobs, to verify this patch.
Fixing:

- de-complex Curl_gtls_verifyserver() by splitting of static
functions for parts of it.
- follow the `goto out` style with common deallocation code
Closes#17941
- rename Curl_oss_check_peer_cert() to Curl_ossl_check_peer_cert()
- leave altname match loop after the first success when the match
was an ip address
- remove static subj_alt_hostcheck() since it did not really do much
- use length based infof() output of altname, even though it does
seem always to be nul terminated
Closes#17940
Ahmad Gani intercepts the sendto syscall to simulate short send, but
curl incorrectly handles it. It keeps resending the version:
sendto(4, "\x05", 1, MSG_NOSIGNAL, NULL, 0) = 1
sendto(4, "\x05", 1, MSG_NOSIGNAL, NULL, 0) = 1
Don't restart the buffer in the `CONNECT_SOCKS_INIT` case if
`sx->outstanding` is not zero. It should continue sending the
advanced buffer.

Closes#17943
To set it before checking for it while enabling `HAVE_INET_NTOP` and
`HAVE_INET_PTON` for Vista (and up) targets.
May have affected winbuild or Visual Studio IDE Project Files.
Follow-up to 68fa9bf3f5#9712Closes#17928
The `transport` to use for a transfer, e.g. TCP/QUIC/UNIX/UDP, is
initially selected by options and protocol used. This is set at the
`struct connectdata` as `transport` member.
During connection establishment, this transport may change due to
Alt-Svc or Happy-Eyeballing. Most common is the switch from TCP to QUIC.
Rename the connection member to `transport_wanted` and add a way to
query the connection for the transport in use via a new connection
filter query.
The filter query can also be used in the happy eyeballing attempts when
code needs to know which transport is used by the "filter below". This
happens in wolfssl initialization, as one example.
Closes#17923
When using winbuild or Visual Studio IDE Project Files.
To simplify and prepare for dropping support for VS2008.
Details:
- fix VS2012 default target to be Windows 8 (was Vista).
Confirmed by CI:
```
-- The C compiler identification is MSVC 17.0.61030.0
-- Found _WIN32_WINNT=0x0602
```
Ref: https://ci.appveyor.com/project/curlorg/curl/builds/51594696/job/elbl0w5n7fmoos2f#L45
It also aligns with the default being Windows 7 for VS2010,
and Windows Vista for VS2008.
- bump minimum target to XP (was Windows 2000) when using VS2008.
curl requires XP.
- add Windows release names to comments for clarity.
- add hex Windows version to a comment for clarity.
- merge VS2008/VS2012 minimum/default logic and comments.
- reduce scope of local minimum/default macros.
- shorten comments to fit within line limit.
Closes#17916
In gtls.c there was a typo'd comment that I think was missing the word
"no" to indicate there's "no GnuTLS way to signal no EarlyData".
This commit fixes that typo, and also updates a copy-pasted instance
that made it into wolfssl.c where it should refer to the WolfSSL API
missing the capability, not GnuTLS.
Closes#17907
To avoid applying it to all other sources in unity mode.
This may have affected tests setting a custom time via `CURL_TIME`,
in unity builds: 446, 780, 781, 782, 783, 970, 972, 1654, 1660
Closes#17897
This callback was permanently mapped to libcurl's internal
`Curl_wcsdup()`, which always uses the customizable malloc for
allocation, thus making a custom mapping redundant anyway.
To simplify, drop the callback and map `_tcsdup()` in Unicode mode
directly to `Curl_wcsdup()`.
Also fixes:
- `curl_global_init()` which, before this patch, (re)initialized its
mapping to `_wcsdup()`, returning buffers potentially incompatible
with a custom allocator.
