In both send/recv functions of the ngtcp2 filter, when TLS verification
has failed, jump out by skipping ingress/egress handling.

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.

- fix `CURLcode` vs. LDAP result code confusion.
Return `LDAP_NO_MEMORY` when `Curl_create_sspi_identity()` fails,
since it can only return `CURLE_OUT_OF_MEMORY` as error.
- use `ULONG` for result code on Windows. Drop casts.
- use portable `curl_ldap_num_t`. Drop casts.
- replace magic number 0 with `LDAP_SUCCESS`.
- compare with `LDAP_SUCCESS` instead of assuming non-zero.
(where necessary.)
- add/fix `#endif` comments.
- fix indentation.
Closes#18888
In a case where rubbish would be sent in the line something that isn't a
digit could be first in line and treated as less than '3'. Prevent this
risk by first doing a check that the byte is a digit.

This adds an extra check that the buffer really has data enough (at
least 4 bytes) to check for a status code before doing so. It *should*
not be necessary, but this was pointed out by an analyzer and it feels
better to make sure.

- curlx_get_winapi_error: accept DWORD (was: int), move casts one level

Also:
- tests/server: replace local `sstrerror()` with `curlx_strerror()`.
- tests/server: show the error code next to the string, where missing.
- curlx: use `curl_msnprintf()` when building for src and tests.
(units was already using it.)
- lib: drop unused includes found along the way.
- curlx_strerror(): avoid compiler warning (and another similar one):

It cannot actually return an error, so the parent function does not need
to check for error and have an exit path that cannot be reached.

i is taken from pointer[length-2] (often the IAC byte) before we do
length -= 2, so using pointer[i] indexes an arbitrary/stale byte
unrelated to the option code. pointer[0] is the suboption’s option code
per the telnet SB format, so printing pointer[0] yields correct, stable
diagnostics.
Closes#18851
Replace `char *dest[1]` with a proper `char dest[1]` array in
cpool_bundle. This removes undefined behavior from memcpy (writing past
the declared object) while keeping the same key semantics: dest_len is
strlen+1 (includes NUL), and hash add/delete calls remain unchanged.

By making them defaults, then fixing and/or reshuffling remaining
exceptions as necessary.
- checksrc: ban by default: `snprintf`, `vsnprintf`, `sscanf`, `strtol`.
- examples: replace `strtol` with `atoi` to avoid a checksrc exception.
- tests/libtest: replace `strtol` with `atol`.
- tests/server: replace most `strtol` with `atol`.
- tests/server: replace most `strtoul` with `atol`/`atoi`.
- tests/server: drop no longer used `util_ultous`.
- fix typo in checksrc rules: `vsnprint` -> `vsnprintf`.
- update local exceptions.
Also:
- examples: ban curl printf functions. They're discouraged in user code.
- examples: replace curl printf with system printf.
Add `snprintf` workaround for <VS2015.
- examples/synctime: fix `-Wfloat-equal`.
- examples/synctime: exclude for non-Windows and non-UWP Windows.
- examples/synctime: build by default.

The new custom_* flags in the SSL config need to be inherited when
setting up the doh easy handle, so that defaults apply the same way as
for the original easy handle.
Closes#18831
Previously the progress meter used a maximum of five digits+letter in
the progress meter output: up to 99999 bytes and then 9999k, 9999M etc.
The output then used two spaces after the size between the next field in
the display.
This new approach uses one letter more with only one space in between
the fields. It makes it possible to show up to 999999 bytes and then
99999k, 99999M etc. The function uses a single decimal when outputting a
value less than 1000 in any unit. Like 999.9M.

- better tracing of what system call is used and how often

- configure/cmake support for enabling the option
- supported in OpenSSL and GnuTLS backends
- when configured, Apple SecTrust is the default trust store

Closes#18803
HTTP/3 defines "reserved stream types" that are intended to be ignored
by a receiver. This is part of the "greasing" effort that flexes parts
of the protocol that are needed for future extensions.
curl's OpenSSL-QUIC implementation treated all unexpected streams as
an error. Which seems the right thing to do *but* for these reserved types.
However OpenSSL does not expose this type and thus, curl needs to silently
discard all unexpected streams opened by the server to allow interop
with servers that flex the GREASE parts.
