For options that pass in lists or strings that are subsequently parsed
and must be correct. This broadens the scope for the option previously
known as CURLE_TELNET_OPTION_SYNTAX but the old name is of course still
provided as a #define for existing applications.

The previous strip also removed the CR which turned problematic.
valgrind.supp: add zstd suppression using hyper

- Check the return code to Curl_inet_pton() in two instances, even
though we know the input is valid so the functions won't fail.
- Clear the 'struct sockaddr_in' struct before use so that the
'sin_zero' field isn't left uninitialized.

Closes#7163
As host names are case insensitive, the use of case sensitive hashing
caused unnecesary cache misses and therefore lost performance. This
lowercases the hash key.

This avoids a TCP reset (RST) if the server initiates a connection
shutdown by sending an SSL close notify alert and then closes the TCP
connection.
For SSL connections, usually the server announces that it will close the
connection with an SSL close notify alert. curl should read this alert.
If curl does not read this alert and just closes the connection, some
operating systems close the TCP connection with an RST flag.
See RFC 1122, section 4.2.2.13
If curl reads the close notify alert, the TCP connection is closed
normally with a FIN flag.
The new code is similar to existing code in the "SSL shutdown" function:
try to read an alert (non-blocking), and ignore any read errors.
Closes#7095
The CMake `try_compile` command is especially slow for
the Xcode generator. With this patch applied it first tests
for the currently used (and Open Group specified) send/recv
signature. In case this fails testing falls-back to the
permutations.

This function might get called for an easy handle for which the session
cache hasn't been setup. It now just returns a "miss" in that case.

Resolving the case insensitive host name 'localhost' now returns the
addresses 127.0.0.1 and (if IPv6 is enabled) ::1 without using any
resolver.
This removes the risk that users accidentally resolves 'localhost' to
something else. By making sure 'localhost' is always local, we can
assume a "secure context" for such transfers (for cookies etc).
Closes#7039
Also, use a single function library-wide for detecting if a given hostname is

Hyper returns the same error for wrong HTTP version as for negative
content-length. Test 178 verifies that negative content-length is
rejected but the hyper backend will return a different error for it (and
without any helpful message telling why the message was bad). It will
also not return any headers at all for the response, not even the ones
that arrived before the error.
Closes#7147
In INSTALL.MD, it's currently set to CURL-DISABLE-md instead of
CURL-DISABLE.md. This generates a 404 on the cURL website as well as
when viewing the docs through Github.
Closes#7142
To prevent previous ones to get reused on subsequent requests. Matches
how the built-in HTTP code works. Makes test 90 to 93 work.
Add test 90 to 93 in travis.
Closes#7139
In a3268eca79 this code was changed to use the ALPN_H2 constant
instead of the NGHTTP2_PROTO_ALPN constant. However, these constants are
not the same. The nghttp2 constant included the length of the string,
like this: "\x2h2". The ALPN_H2 constant is just "h2". Therefore we need
to re-add the length of the string to the ALPN buffer.
Closes#7138
