Ref: #6899
Add parser for CURLOPT_SSL_CIPHER_LIST option for Secure Transport (ST)
back-end. Similar to NSS and GSKit back-ends, new code parses string
value and configures ST library to use those ciphers for communication.
Create cipher spec data structure and initialize the array of specs with
cipher number, name, alias, and 'weak' flag.
Mark triple-DES ciphers as 'weak', and exclude them from the default
ciphers list.
Closes#6464
By using #ifdef on the symbol names to work on anything that don't
provide them. SCO OpenServer 5.0.7, sys/socket.h does not define either
SHUT_RDWR, SHUT_RD, and SHUT_WR.

The ConnectionExists() function will note that the new transfer wants
less then h2 and that it can't multiplex it and therefor opt to open a
new connection instead.
Storing a stream error in the per-connection struct was an error that lead to
race conditions as subsequent stream handling could overwrite the error code
before it was used for the stream with the actual problem.
Closes#6910
This was this one condition where the stream could be closed due to an
error and the function would still wrongly just return 0 for it.

- Save a parallel transfer's result code only when it fails and the
transfer is not being retried.
Prior to this change the result code was always set which meant that a
failed result could be erroneously discarded if a different transfer
later had a successful result (CURLE_OK).
Before:
> curl --fail -Z https://httpbin.org/status/404https://httpbin.org/delay/10
> echo %ERRORLEVEL%
0
After:

UTM parameters leak referrer and various marketing/tracking information

Closes#6919
When the host name in a URL is given as an IPv4 numerical address, the
address can be specified with dotted numericals in four different ways:
a32, a.b24, a.b.c16 or a.b.c.d and each part can be specified in
decimal, octal (0-prefixed) or hexadecimal (0x-prefixed).
Instead of passing on the name as-is and leaving the handling to the
underlying name functions, which made them not work with c-ares but work
with getaddrinfo, this change now makes the curl URL API itself detect
and "normalize" host names specified as IPv4 numericals.
The WHATWG URL Spec says this is an okay way to specify a host name in a
URL. RFC 3896 does not allow them, but curl didn't prevent them before
and it seems other RFC 3896-using tools have not either. Host names used
like this are widely supported by other tools as well due to the
handling being done by getaddrinfo and friends.
I decided to add the functionality into the URL API itself so that all
users of these functions get the benefits, when for example wanting to
compare two URLs. Also, it makes curl built to use c-ares now support
them as well and make curl builds more consistent.
The normalization makes HTTPS and virtual hosted HTTP work fine even
when curl gets the address specified using one of the "obscure" formats.
Test 1560 is extended to verify.

... previously they were supported if a TLS library would (unexpectedly)

curl_easy_setopt(). SSLv2 and SSLv3 have been known to be insecure for
many years now.

Instead output a warning about it and continue with the defaults.
These SSL versions are typically not supported by the TLS libraries since a
long time back already since they are inherently insecure and broken. Asking
for them to be used will just cause an error to be returned slightly later.
In the unlikely event that a user's TLS library actually still supports these
protocol versions, this change might make the request a little less insecure.
Closes#6772
The code in cr_recv was returning prematurely as soon as the socket
reported no more data to read. However, this could be leaving some
unread plaintext data in the rustls session from a previous call,
causing causing the transfer to hang if the socket never receives
further data.
We need to ensure that the session is fully drained of plaintext data
before returning CURLE_AGAIN to the caller.

According to Microsoft document MS-NLMP, current flags usage is not
accurate: flag NTLMFLAG_NEGOTIATE_NTLM2_KEY controls the use of
extended security in an NTLM authentication message and NTLM version 2
cannot be negotiated within the protocol.
The solution implemented here is: if the extended security flag is set,
prefer using NTLM version 2 (as a server featuring extended security
should also support version 2). If version 2 has been disabled at
compile time, use extended security.
Tests involving NTLM are adjusted to this new behavior.

In 2682e5f5, several instances of AC_HEADER_TIME were removed since
it is a deprecated autoconf macro. However, this was the macro that
defined TIME_WITH_SYS_TIME, which was used to indicate that <time.h>
can be included alongside <sys/time.h>. TIME_WITH_SYS_TIME is still
used in the configure test body and since it is no longer defined,
<time.h> is *not* included on systems that have <sys/time.h>.
In particular, at least on musl libc and glibc, <sys/time.h> does
not implicitly include <time.h> and does not declare clock_gettime,
gmtime_r, or localtime_r. This causes configure to fail to detect
those functions.
The AC_HEADER_TIME macro deprecation text says
> All current systems provide time.h; it need not be checked for.
> Not all systems provide sys/time.h, but those that do, all allow
> you to include it and time.h simultaneously.
So, to fix this issue, simply include <time.h> unconditionally when
testing for time-related functions and in libcurl, and don't bother
checking for it.
Closes#6859
This was previously defined by the obsolete AC_TYPE_SIGNAL macro,
which was removed in 2682e5f5. The deprecation text says

So, remove it and just use void instead.
