Expose devices allocated for tun/tap forwarding.
At the client, the device may be obtained from a new %T expansion
for LocalCommand.
At the server, the allocated devices will be listed in a
SSH_TUNNEL variable exposed to the environment of any user sessions
started after the tunnel forwarding was established.

Add URI support to ssh, sftp and scp. For example
ssh://user@host or sftp://user@host/path. The connection parameters
described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since
the ssh fingerprint format in the draft uses md5 with no way to specify the
hash function type. OK djm@

In the description of pattern-lists, clarify negated
matches by explicitly stating that a negated match will never yield a
positive result, and that at least one positive term in the pattern-list must
match. bz#1918

replace statically-sized arrays in ServerOptions with
dynamic ones managed by xrecallocarray, removing some arbitrary (though
large) limits and saving a bit of memory; "much nicer" markus@

We don't support openssl-1.1.x yet (see multiple threads on the
openssh-unix-dev@ mailing list for the reason), but previously
./configure would accept it and the compilation would subsequently
fail. This makes ./configure display an explicit error message and
abort.

On some platforms (AIX, maybe others) allocating zero bytes of memory
via the various *alloc functions returns NULL, which is permitted
by the standards. Autoconf has some macros for detecting this (with
the exception of calloc for some reason) so use these and if necessary
activate shims for them. ok djm@

write the correct buffer when tunnel forwarding; doesn't
matter on OpenBSD (they are the same) but does matter on portable where we
use an output filter to translate os-specific tun/tap headers

Add 'reverse' dynamic forwarding which combines dynamic
forwarding (-D) with remote forwarding (-R) where the remote-forwarded port
expects SOCKS-requests.
The SSH server code is unchanged and the parsing happens at the SSH
clients side. Thus the full SOCKS-request is sent over the forwarded
channel and the client parses c->output. Parsing happens in
channel_before_prepare_select(), _before_ the select bitmask is
computed in the pre[] handlers, but after network input processing
in the post[] handlers.

It's still on by default, but now it's possible to turn it off using

with some -fsanitize options. ok dtucker@
Print SKIPPED if sudo and doas configuration is missing.
Prevents that running the regression test with wrong environment is reported
as failure. Keep the fatal there to avoid interfering with other setups for
portable ssh. OK dtucker@

Don't call fatal from stop_sshd since it calls cleanup
which calls stop_sshd which will probably fail in the same way. Instead,
just bail. Differentiate between sshd dying without cleanup and not shutting
down.
