[PATCH] Add scp -1 and -2 options to OpenSSH-3.0.2p1

[Markus Friedl]

i don't like the idea of 'linking' scp to ssh.

having non-rcp options in scp is a very bad idea, scp should be
independant of the 'transport' that gets used and not depend on any
ssh option or a specific ssh implementation.

rsync does not depend on ssh options, so scp should either.

most of the duplicated ssh options are inherited from scp,
so it's hard to change.

i'd prefer to remove -c, -i, -B, -4, -6 from scp, but it's too
late.
