The mistake is harmless because it is still a size of a pointer, but
this is the correct pointer.

It also means that all supported OpenSSL versions and forks support
TLSv1.3 after this patch.
It reduces `openssl.c` size by more than 10%, or 400 LOC.

Windows CE support was limited to successful builds with ming32ce
(a toolchain that hasn't seen an update since 2009, using an ancient gcc
version and "old mingw"-style SDK headers, that curl deprecated earlier).
Builds with MSVC were broken for a long time. mingw32ce builds were never
actually tested and runtime and unlikely to work due to missing stubs.
Windows CE toolchains also miss to comply with C89. Paired with lack of
demand and support for the platform, curl deprecated it earlier.
This patch removes support from the codebase to ease maintaining Windows
codepaths.

- badwords.pl: add `-a` option to check all lines in source code files.
Before this patch indented lines were skipped (to avoid Markdown code
fences.)
- GHA/checksrc: use `-a` when verifying the source code.
- GHA/checksrc: disable `So` and `But` rules for source code.
- GHA/checksrc: add docs/examples to the verified sources.
- badwords.txt: delete 4 duplicates.
- badwords.txt: group and sort contractions.
- badwords.txt: allow ` url = `, `DIR`, `<file name`.

Move out logic from a switch() expression and return error directly

Rename `Curl_timeleft()` to `Curl_timeleft_ms()` to make the units in
the returned `timediff_t` clear. (We used to always have ms there, but
with QUIC started to sometimes calc ns as well).
Rename some assigned vars without `_ms` suffix for clarity as well.

files fully.
- pyspelling.words: drop `cURL` allowed word.

A regression in curl 8.17.0 led to a customer CAPATH set by the
application (or the curl command) to be ignored unless licurl was built
with a default CAPATH.
Add test cases using `--capath` on the custom pytest CA, generated with
the help of the openssl command when available.

When Curl_conn_cf_recv() returns error, the variable might not be
assigned and the tracing output may (harmlessly) use it uninitialized.
Also add a comment about the typecast from size_t to int being fine.

With GnuTLS 3.8.0+ the build-time SRP feature detection always succeeds.
It's also disabled by default in these GnuTLS versions.
When using TLS-SRP without it being available in GnuTLS, report
the correct error code `CURLE_NOT_BUILT_IN`, replacing the out of memory
error reported before this patch.
Also add comments to autotools and cmake scripts about this feature
detection property.
Detecting it at build-time would need to run code which doesn't work
in cross-builds. Once curl requires 3.8.0 as minimum, the build-time
checks can be deleted.
```
# before:
curl: (27) gnutls_srp_allocate_client_cred() failed: An unimplemented or disabled feature has been requested.
# after:
curl: (4) GnuTLS: TLS-SRP support not built in: An unimplemented or disabled feature has been requested.

This commit does the following things:
1. Update the description of gtls_init()
2. In gtls_client_init(), check the invaild SSLVERSION at first. Note
that this part refactors the duplicate/incompatible checks and removes
the useless local variable `sni`.
3. Check the return value of gnutls_ocsp_resp_init(). Although the
original code is safe because gnutls_ocsp_resp_import() will check
the validity of `ocsp_resp`, it is better to catch the error in time
and record the proper message to output log.
Closes#19366
find_ssl_filter used while(cf && cf->next) and skipped the last node.
If the SSL filter was last, channel binding lookup failed and we returned
CURLE_BAD_FUNCTION_ARGUMENT. Switch to while(cf) so the tail is examined.
This bug was found with ZeroPath.

The definition of these constants does not give a numeric ordering

When openssl does not verify the certificate, but apple sectrust
does, we also pass it the ocsp stapled response when configured and
available.
When openssl does not verify the cert chain, it will also not be able
to verify the ocsp stapling. Do not call it if sectrust is the
verifier of the cert chain.

Replace the check if a ssl session cache is configured with
a function checking if it is configured *and* if an ssl session
cache is available.
During normal operations, a session cache is always there, however
for "connect-only" transfers this might not be the case. When such
transfers receive new sessions/tickets, they need to silently
discard those and not fail.

Change the test certificate to carry a altname 'dns:127.0.0.1' which
should *not* match in test_17_05_bad_ip_addr.
wolfSSL: since `wolfSSL_check_domain_name()` does not differentiate
between DNS and IP names, use if only for DNS names. For IP addresses,
get the peer certificate after the handshake and check that using
wolfSSL_X509_check_ip_asc().
Unfortunately, this succeeds where it should not, as wolfSSL internally
used the same check code for both cases. So, skip the test case until
wolfSSL fixes that.

Make autotools and cmake detect DES support in OpenSSL and mbedTLS.
Forward feature macros to C and omit NTLM from the feature preview list.
Use the feature macros in source. This ensure that `-V` output matches
the preview.
OpenSSL doesn't support DES when built with `no-des` or `no-deprecated`.
mbedTLS 4.x no longer supports it, and it's possible to disable it in
<4 with `scripts/config.py unset MBEDTLS_DES_C`.
Before this patch this worked for
mbedTLS 4 only, and with a regression for pending PR #16973.
Also:
- drop NTLM feature check from `curl_setup.h` in favour of autotools/
cmake feature macros. This makes `curl_setup.h` no longer need
to include an mbedTLS header, which in turn makes tests/server build
without depending on mbedTLS.
Fixing, in #16973:
