Fixes#402
When the user is not set as away, using the
`/back` or `/away` command should return error.
The previous behaviour was inconsistent,
`/away` sent a message and `/back` ignored it.
New behaviour is error for both cases.

* Move password authentication handling into sshd/auth (fixes#394).
Password authentication is now completely handeled in Auth. The normal
keyboard-interactive handler checks if passwords are supported and asks
for them, removing the need to override the callbacks.
Brute force throttling is removed; I'd like to base it on IP address
banning, which requires changes to the checks.
I'm not sure, but I think timing attacks against the password are fixed:
- The hashing of the real password happens only at startup.
- The hashing of a provided password is something an attacker can do
themselves; It doesn't leak anything about the real password.
- The hash comparison is constant-time.
* refactor checks, IP-ban incorrect passphrases, renames
- s/assword/assphrase/, typo fixes
- bans are checked separately from public keys
- an incorrect passphrase results in a one-minute IP ban
- whitelists no longer override bans (i.e. you can get banned if you're
whitelisted)
* (hopefully) final changes
* Fixes Env Vars to pass config to ssh-chat.
The env vars were beign parsed and set to the host
before the user was even added to the host and
hence ignored. This change moves the env var parsing
to after initializing the user.
TODO: tests, completeness+reliability
* cleaned up the test
* reduced test flakyness by adding wait instead of being optimistic
