The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

The tests 20 and 1322 are using getaddrinfo of libc for resolving. In
eglibc-2.19 there is a memory leakage and invalid free bug which
surfaces in some special circumstances (PF_UNSPEC hint with invalid or
non-existent names). The valgrind runs in testing fail in these
situations.
As the tests 20/1322 are not specific on either protocol (IPv4/IPv6)
this commit changes the hints to IPv4 protocol by passing `--ipv4` flag
on the tests' command line. This prevents the valgrind failures.
Session resumption information is not available immediately after a TLS 1.3
handshake. The client must wait until the server has sent a session ticket.
Use OpenSSL's "new session" callback to get the session information and put it
into curl's session cache. For TLS 1.3 sessions, this callback will be invoked
after the server has sent a session ticket.
The "new session" callback is invoked only if OpenSSL's session cache is
enabled, so enable it and use the "external storage" mode which lets curl manage
the contents of the session cache.
A pointer to the connection data and the sockindex are now saved as "SSL extra
data" to make them available to the callback.
This approach also works for old SSL/TLS versions and old OpenSSL versions.

Since we're close to feature freeze, this change disables this feature
with an #ifdef. Define ALLOW_RENEG at build-time to enable.
This could be converted to a bit for CURLOPT_SSL_OPTIONS to let

When using c-ares for asyn dns, the dns socket fd was silently closed
by c-ares without curl being aware. curl would then 'realize' the fd
has been removed at next call of Curl_resolver_getsock, and only then
notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with
CURL_POLL_REMOVE. At this point the fd is already closed.
By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this
patch allows curl to be notified that the fd is not longer needed
for neither for write nor read. At this point by calling
Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE
before the fd is actually closed by ares.
In asyn-ares.c Curl_resolver_duphandle we can't use ares_dup anymore
since it does not allow passing a different sock_state_cb_data

lib/curl_ntlm.c had code that read as follows:

Remove the redundant USE_OPENSSL along with #else (it's not possible to
reach it anyway). The removed construction is a leftover from when the
SSLeay support was removed.

The partial struct initialization in 397664a065 caused
a warning on uninitialized MODULEENTRY32 struct members:
/src/tool_doswin.c:681:3: warning: missing initializer for field
'th32ModuleID' of 'MODULEENTRY32 {aka struct tagMODULEENTRY32}'

This is sort of a bogus warning as the remaining members will be set
to zero by the compiler, as all omitted members are. Nevertheless,
remove the warning by omitting all members and setting the dwSize
members explicitly.

The SSL_CTX_set_msg_callback callback is not just called for the
Handshake or Alert protocols, but also for the raw record header
(SSL3_RT_HEADER) and the decrypted inner record type
(SSL3_RT_INNER_CONTENT_TYPE). Be sure to ignore the latter to avoid
excess debug spam when using `curl -v` against a TLSv1.3-enabled server:
* TLSv1.3 (IN), TLS app data, [no content] (0):
(Following this message, another callback for the decrypted
handshake/alert messages will be be present anyway.)

Commit 5bfaa86ceb introduced a new
compiler warning on Windows cross compilation with GCC. See below
for an example of the warning from the autobuild logs (whitespace
edited to fit):
/src/tool_cb_wrt.c:175:9: warning: cast from function call of type
'intptr_t {aka long long int}' to non-matching type 'void *'
[-Wbad-function-cast]
(HANDLE) _get_osfhandle(fileno(outs->stream)),
^
Store the return value from _get_osfhandle() in an intermediate
variable and cast the variable in WriteConsoleW() rather than the
function call directly to avoid a compiler warning.
In passing, also add inspection of the MultiByteToWideChar() return
value and return failure in case an error is reported.

- Add an undocumented diagnostic option for Windows to show the full
paths of all loaded modules regardless of whether or not libcurl
initialization succeeds.
This is needed so that in the CI we can get a list of all DLL
dependencies after initialization (when they're most likely to have
finished loading) and then package them as artifacts so that a
functioning build can be downloaded. Also I imagine it may have some use
as a diagnostic for help requests.
