- the data needs to be "line-based" anyway since it's also passed to the
debug callback/application
- it makes infof() work like failf() and consistency is good
- there's an assert that triggers on newlines in the format string
- Also removes a few instances of "..."
- Removes the code that would append "..." to the end of the data *iff*
it was truncated in infof()
Closes#7357
Avoid the race condition risk by instead storing the "seeded" flag in
the multi handle. Modern OpenSSL versions handle the seeding itself so
doing the seeding once per multi-handle instead of once per process is
less of an issue.

Introducing a 'isproxy' argument to the connect function so that it
knows wether to store the time stamp or not.

For the commandline tool, we expect to be passed
SSL_CONN_CONFIG(CAfile); for library use, the use should pass a set of
trusted roots (like in other TLS backends).
This also removes a dependency on Security.framework when building on
macOS.

When a connection is disassociated from a transfer, the Session ID entry
should remain.

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
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.

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
When the SecCertificateCopyCommonName function fails, it leaves
common_name in a invalid state so CFStringCompare uses the invalid
result, causing EXC_BAD_ACCESS.
The fix is to check the return value of the function before using the
name.
Closes#7126
As of commit 54e7475, these flags would only be set when using a new
credential handle. When re-using an existing credential handle, the
flags would not be set.

Previously, settting only the max allowed TLS version, leaving the
minimum one at default, didn't actually set it and left it to default
(TLS 1.3) too!
As a bonus, this change also removes the dead code handling of SSLv3
since that version can't be set anymore (since eff614fb02).

When a TLS server requests a client certificate during handshake and
none can be provided, libcurl now returns this new error code
CURLE_SSL_CLIENTCERT
Only supported by Secure Transport and OpenSSL for TLS 1.3 so far.
Closes#6721
Removed localfd and remotefd from ssl_backend_data (ued only with proxy
connection). Function pipe_ssloverssl return always 0, when proxy is not
used.
Closes#6981
This abstracts across the two HTTP/2 backends: nghttp2 and Hyper.
Add our own define for the "h2" ALPN protocol, so TLS backends can use
it without depending on a specific HTTP backend.
Closes#6959
