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
applications opt-in this.

Fixes#3283Closes#3293
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
Closes#3238
lib/curl_ntlm.c had code that read as follows:
#ifdef USE_OPENSSL
# ifdef USE_OPENSSL
# else
# ..
# endif
#endif
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 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.)

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.

Prior to this change twice as many bytes as necessary were malloc'd when
converting wchar to UTF8. To allay confusion in the future I also
changed the variable name for the amount of bytes from len to bytes.

- for "--netrc", don't ignore the login/password specified with "--user",
only ignore the login/password in the URL.
This restores the netrc behaviour of curl 7.61.1 and earlier.
- fix the documentation of CURL_NETRC_REQUIRED
- improve the detection of login/password changes when reading .netrc
- don't read .netrc if both login and password are already set

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.

Ensure to clear the session object in case the libssh2 initialization
fails.
It could be argued that the libssh2 error function should be called to
get a proper error message in this case. But since the only error path
in libssh2_knownhost_init() is memory a allocation failure it's safest
to avoid since the libssh2 error handling allocates memory.
