... as they're checked for in the configure script and are used by
source code.
Removed checks for perror, setvbuf and strlcat since those defines are
not checked for in source code.
Bonus: removed HAVE_STRLCPY from a few config-*.h files since that
symbol is not used in source code.
Closes#6997
... to avoid memory leaks!
libssh2 is tricky as we have to deal with the non-blockiness even in
close and shutdown cases. In the cases when we shutdown after a timeout
already expired, it is crucial that curl doen't let the timeout abort
the shutdown process as that then leaks memory!

Fixes#6990
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.

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
Previously if a caller set CURLOPT_WRITEFUNCTION but did not set a
CURLOPT_HEADERDATA buffer, Hyper would still attempt to write headers to
the data->set.writeheader header buffer, even though it is null. This
led to NPE segfaults attempting to use libcurl+Hyper with Git, for
example.
Instead, process the client write for the status line using the same
logic we use to process the client write for the later HTTP headers,
which contains the appropriate guard logic. As a side benefit,
data->set.writeheader is now only read in one file instead of two.

Previously compiling rustls on Mac would only complete if you also
compiled the SecureTransport TLS backend, which curl would prefer to
the Rust backend.
Appending these flags to LDFLAGS makes it possible to compile the
Rustls backend on Mac without the SecureTransport backend, which means
this patch will make it possible for Mac users to use the Rustls
backend for TLS.

Cloes #6956
wording taken from man page for CURLOPT_URL.3
As far as I can see, the URL part is either malloc'ed before due to
encoding or it is strdup'ed.
