Previously, if for example the nonce would end with "realm=" etc it
would get the wrong piece, due to the naive parser.

Closes#18975
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.

Drop `strcasecompare` and `strncasecompare` in favor of libcurl API
calls `curl_strequal` and `curl_strnequal` respectively.
Also drop unnecessary `strcase.h` includes. Include `curl/curl.h`
instead where it wasn't included before.

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.

Closes#17253
by including headers using "../[header]" when done from C files in
subdirectories, we do not need to specify the lib source dir as an
include path and we reduce the risk of header name collisions with
headers in the SDK using the same file names.

To reduce the number `-Wunused-macro` compiler warnings:
- delete unused macros.
- comment out unused macro that are part of a set.
- move macros into the scope they are used.
This may be useful to enable by default, but there are tricky cases that
I didn't manage to fix and paused the effort. E.g. internal features
checks in `openssl.c`. There is more, once those are fixed.
Closes#16279
Other programs (Postman, Chrome, Python request) use a 16 byte cnonce

krb5 defines `strtok_r` for Windows unconditionally in its public
header:
dc5554394e/src/include/win-mac.h (L214-L215)
resulting in this warning:
```
lib\strtok.h(31,9): warning C4005: 'strtok_r': macro redefinition
C:\vcpkg\installed\x64-windows\include\win-mac.h(215,9):
see previous definition of 'strtok_r'
```
The krb5 macro collides with curl's internal definition, in case
the `strtok_r` function is undetected and falling back to a local
replacement.

Also fix the tests. New implementation tested with GNU libmicrohttpd.
The new numbers in tests are real SHA-512/256 numbers (not just some
random ;) numbers ).
Enable more picky compiler warnings. I've found these options in the
nghttp3 project when implementing the CMake quick picky warning
functionality for it [1].
`-Wunused-macros` was too noisy to keep around, but fixed a few issues
it revealed while testing.
- autotools: reflect the more precisely-versioned clang warnings.
Follow-up to 033f8e2a08#12324
- autotools: sync between clang and gcc the way we set `no-multichar`.
- autotools: avoid setting `-Wstrict-aliasing=3` twice.
- autotools: disable `-Wmissing-noreturn` for MSYS gcc targets [2].
It triggers in libtool-generated stub code.
- lib/timeval: delete a redundant `!MSDOS` guard from a `WIN32` branch.
- lib/curl_setup.h: delete duplicate declaration for `fileno`.
Added in initial commit ae1912cb0d
(1999-12-29). This suggests this may not be needed anymore, but if
it does, we may restore this for those specific (non-Windows) systems.
- lib: delete unused macro `FTP_BUFFER_ALLOCSIZE` since
c1d6fe2aaa.
- lib: delete unused macro `isxdigit_ascii` since
f65f750742.
- lib/mqtt: delete unused macro `MQTT_HEADER_LEN`.
- lib/multi: delete unused macro `SH_READ`/`SH_WRITE`.
- lib/hostip: add `noreturn` function attribute via new `CURL_NORETURN`
macro.
- lib/mprintf: delete duplicate declaration for `Curl_dyn_vprintf`.
- lib/rand: fix `-Wunreachable-code` and related fallouts [3].
- lib/setopt: fix `-Wunreachable-code-break`.
- lib/system_win32 and lib/timeval: fix double declarations for
`Curl_freq` and `Curl_isVistaOrGreater` in CMake UNITY mode [4].
- lib/warnless: fix double declarations in CMake UNITY mode [5].
This was due to force-disabling the header guard of `warnless.h` to
to reapply it to source code coming after `warnless.c` in UNITY
builds. This reapplied declarations too, causing the warnings.
Solved by adding a header guard for the lines that actually need
to be reapplied.
- lib/vauth/digest: fix `-Wunreachable-code-break` [6].
- lib/vssh/libssh2: fix `-Wunreachable-code-break` and delete redundant
block.
- lib/vtls/sectransp: fix `-Wunreachable-code-break` [7].
- lib/vtls/sectransp: suppress `-Wunreachable-code`.
Detected in `else` branches of dynamic feature checks, with results
known at compile-time, e.g.
```c
if(SecCertificateCopySubjectSummary) /* -> true */
```
Likely fixable as a separate micro-project, but given SecureTransport
is deprecated anyway, let's just silence these locally.
- src/tool_help: delete duplicate declaration for `helptext`.
- src/tool_xattr: fix `-Wunreachable-code`.
- tests: delete duplicate declaration for `unitfail` [8].
- tests: delete duplicate declaration for `strncasecompare`.
- tests/libtest: delete duplicate declaration for `gethostname`.
Originally added in 687df5c8c3
(2010-08-02).
Got complicated later: c49e9683b8
If there are still systems around with warnings, we may restore the
prototype, but limited for those systems.
- tests/lib2305: delete duplicate declaration for
`libtest_debug_config`.
- tests/h2-download: fix `-Wunreachable-code-break`.

In https://www.rfc-editor.org/rfc/rfc2831#section-2.1.2
digest-uri-value should be serv-type "/" host , where host is:
The DNS host name or IP address for the service requested. The
DNS host name must be the fully-qualified canonical name of the
host. The DNS host name is the preferred form; see notes on server
processing of the digest-uri.
Realm may not be the host, so we must specify the host explicitly.
Note this change only affects the non-SSPI digest code. The digest code
used by SSPI builds already uses the hostname to generate the spn.

Instances of ISSPACE() use that should rather use ISBLANK(). I think
somewhat carelessly used because it sounds as if it checks for space or
whitespace, but also includes %0a to %0d.
For parsing purposes, we should only accept what we must and not be
overly liberal. It leads to surprises and surprises lead to bad things.

RFC 7616 (and 2617) requires values to be "unquoted" before used for
digest calculations. The only place where unquoting can be done
correctly is header parsing function (realm="DOMAIN\\host" and
realm=DOMAN\\host are different realms).
This commit adds unquoting (de-escaping) of all values during header
parsing and quoting of the values during header forming. This approach
should be most straightforward and easy to read/maintain as all values
are processed in the same way as required by RFC.
Closes#8912

RFC 7616 section 3.4 (The Authorization Header Field) states that "For
historical reasons, a sender MUST NOT generate the quoted string syntax
for the following parameters: algorithm, qop, and nc". This removes the
