scp: now using SFTP protocol by default

[Damien Miller]

FYI: the next release will have scp using the SFTP protocol by
default.

There are two known incompatibilities:

Use of the SFTP protocol avoids interpretation of remote paths by
the shell. We consider this a feature, but it does change (simplify
really) necessary quoting of shell characters.

Remote paths with a ~user/ prefix require a SFTP protocol extension
that was included in OpenSSH 8.7's sftp-server.

The original scp/rcp protocol remains available via "scp -O ..."

If you're in a position to test snapshots/git prior to release
(ETA October), then it would be appreciated.

    upstream: Use the SFTP protocol by default. The original scp/rcp
    
    protocol remains available via the -O flag.
    
    Note that ~user/ prefixed paths in SFTP mode require a protocol extension
    that was first shipped in OpenSSH 8.7.
    
    ok deraadt, after baking in snaps for a while without incident
