upstream: New EnableEscapeCommandline ssh_config(5) option
This option (default "no") controls whether the ~C escape is available.
Turning it off by default means we will soon be able to use a stricter
default pledge(2) in the client.

upstream: add a RequiredRSASize for checking RSA key length in
ssh(1). User authentication keys that fall beneath this limit will be
ignored. If a host presents a host key beneath this limit then the connection
will be terminated (unfortunately there are no fallbacks in the protocol for
host authentication).

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.
