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 5bfaa86c

 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.

Curl_ftp_parselist: avoid unsigned integer overflows

The overflow has no real world impact, just avoid it for "best
practice".

As per BoringSSL porting documentation [1], BoringSSL rejects peer
renegotiations by default.

curl fails when trying to authenticate to server through client
certificate if it is requested by server after the initial TLS
handshake.

Enable renegotiation by default with BoringSSL to get same behavior as
with OpenSSL. This is done by calling SSL_set_renegotiate_mode [2]
which was introduced in commit 1d5ef3bb1eb9 [3].

The tool's local port command line range parser didn't check for integer

libcurl however, has a strict range check for the values so it rejects

- 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.

The previous coding used a format string whose output depended on the
current locale of the environment running the test. Since the gist of
the test is to have a format string, with the actual formatting being

The internal buffer in infof() is limited to 2048 bytes of payload plus
an additional byte for NULL termination. Servers with very long error
messages can however cause truncation of the string, which currently
isn't very clear, and leads to badly formatted output.

This appends a "...\n" (or just "..." in case the format didn't with a
newline char) marker to the end of the string to clearly show
that it has been truncated.

Also include a unittest covering infof() to try and catch any bugs
introduced in this quite important function.
