Curl_ftp_parselist: avoid unsigned integer overflows

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

Closes #3225

The end port number in a given range was not included in the range used,
as it is documented to be.

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
overflows and could pass "weird" data to libcurl for this option.
libcurl however, has a strict range check for the values so it rejects
anything outside of the accepted range.

Similar to how URL decoding/encoding is done, we could have URL

APPENDQUERY + URLENCODE would skip all equals signs but now it only skip

The function identifying a leading "scheme" part of the URL considered a
few letters ending with a colon to be a scheme, making something like
"short:80" to become an unknown scheme instead of a short host name and
a port number.

Extended test 1560 to verify.

Also fixed test203 to use file_pwd to make it get the correct path on
windows. Removed test 2070 since it was a duplicate of 203.

- 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.

Prior to this change twice as many bytes as necessary were malloc'd when

- improve the detection of login/password changes when reading .netrc
- don't read .netrc if both login and password are already set

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
less important, switch to a more stable formatstring with decimals.

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.
