NTLM: disable if DES support missing from OpenSSL or mbedTLS
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:
  ```
  In file included from tests/server/first.h:40,
                   from bld/tests/server/servers.c:3:
  lib/curl_setup.h:741:10: fatal error: mbedtls/version.h: No such file or directory
    741 | #include <mbedtls/version.h>
        |          ^~~~~~~~~~~~~~~~~~~
  ```

  Follow-up to 3a305831d1 #19077

- move back mbedTLS header include and version check from
  `curl_setup.h` to each source which consumes mbedTLS.

- GHA/http3-linux: drop workaround that disabled NTLM for
  `no-deprecated` OpenSSL builds.

mbedtls: add support for 4.0.0
After this patch libcurl requires (as already documented)
the `curl_global_init()` call when using the `curl_formadd()` API with
mbedTLS.

Note: NTLM is not supported with mbedTLS 4+, because it lacks
the necessary crypto primitive: DES.

Also:
- lib: de-dupe mbedTLS minimum version checks into `curl_setup.h`.
- lib: initialize PSA Crypto as part of `curl_global_init()`.
  For MD5, SHA-256, `curl_formadd()`, and MultiSSL builds with mbedTLS
  but where mbedTLS isn't the default backend.
- lib1308: fix to call `curl_global_init()` (for the Form API).
- curl_ntlm_core: disable with mbedTLS 4+.
- md4: disable mbedTLS implementation when building against 4.x.
- md5: use mbedTLS PSA Crypto API when available, otherwise use
  the default local implementation.
- sha256: use mbedTLS PSA Crypto API when available, otherwise use
  the default local implementation.
- vtls/mbedtls: drop PSA Crypto initialization in favor of
  `curl_global_init()`.
- vtls/mbedtls: use PSA Crypto random API with all mbedTLS versions.
- vtls/mbedtls: do the same for the SHA-256 callback.
- autotools: detect mbedTLS 4+, and disable NTLM for 3.x.
- cmake: disable NTLM for mbedTLS 3.x.
- GHA/linux: keep building mbedTLS 3.x manually and use it in
  an existing job, while also enabling pytest in it.
- GHA/linux: bump to mbedTLS 4.0.0.

lib: stop overriding system printf symbols
After this patch, the codebase no longer overrides system printf
functions. Instead it explicitly calls either the curl printf functions
`curl_m*printf()` or the system ones using their original names.

Also:
- drop unused `curl_printf.h` includes.
- checksrc: ban system printf functions, allow where necessary.

curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

build: enable -Wcast-qual, fix or silence compiler warnings
The issues found fell into these categories, with the applied fixes:

- const was accidentally stripped.
  Adjust code to not cast or cast with const.

- const/volatile missing from arguments, local variables.
  Constify arguments or variables, adjust/delete casts. Small code
  changes in a few places.

- const must be stripped because an API dependency requires it.
  Strip `const` with `CURL_UNCONST()` macro to silence the warning out
  of our control. These happen at API boundaries. Sometimes they depend
  on dependency version, which this patch handles as necessary. Also
  enable const support for the zlib API, using `ZLIB_CONST`. Supported
  by zlib 1.2.5.2 and newer.

- const must be stripped because a curl API requires it.
  Strip `const` with `CURL_UNCONST()` macro to silence the warning out
  of our immediate control. For example we promise to send a non-const
  argument to a callback, though the data is const internally.

- other cases where we may avoid const stripping by code changes.
  Also silenced with `CURL_UNCONST()`.

- there are 3 places where `CURL_UNCONST()` is cast again to const.
  To silence this type of warning:
  ```
  lib/vquic/curl_osslq.c:1015:29: error: to be safe all intermediate
    pointers in cast from 'unsigned char **' to 'const unsigned char **'
    must be 'const' qualified [-Werror=cast-qual]
  lib/cf-socket.c:734:32: error: to be safe all intermediate pointers in
    cast from 'char **' to 'const char **' must be 'const' qualified
    [-Werror=cast-qual]
  ```
  There may be a better solution, but I couldn't find it.

These cases are handled in separate subcommits, but without further
markup.

If you see a `-Wcast-qual` warning in curl, we appreciate your report
about it.

amissl: make AmiSSL v5 a minimum requirement
AmiSSL v5 is the latest version, featuring a port of OpenSSL 3.0.
Support for previous OpenSSL 1.1.x versions has been dropped, so
makes sense to enforce v5 as the minimum requirement. This also
allows all the AmiSSL stub workarounds to be removed as they are
now provided in a link library in the AmiSSL SDK.

0e5c4f574b md5: refactor for standard compliance
- Wrap OpenSSL / wolfSSL MD5 functions instead of taking their function
  addresses during static initialization.

Depending on how curl was built the old way may have used a dllimport
function address during static initialization, which is not standard
compliant, resulting in Visual Studio warning C4232 (nonstandard
extension). Instead the function pointers now point to the wrappers
which call the MD5 functions.

This change only affects OpenSSL and wolfSSL because calls to other SSL
libraries' md5 functions were already wrapped. Also sha256.c already
does this for all SSL libraries.
