This fork golang.org/x/crypto/ssh (at upstream x/crypto git rev e47973b1c1)
into tailscale.com/tempfork/sshtest/ssh so we can hack up the client in weird
ways to simulate other SSH clients seen in the wild.
Two changes were made to the files when they were copied from x/crypto:
* internal/poly1305 imports were replaced by the non-internal version;
no code changes otherwise. It didn't need the internal one.
* all decode-with-passphrase funcs were deleted, to avoid
using the internal package x/crypto/ssh/internal/bcrypt_pbkdf
Then the tests passed.
