Explicitly enable hardware flow control
Better serial set-up

The serial flags we used weren't entirely correct:
- No need for cr handling (really)
- ~PARENB needs to be &-masked in, not |-masked (whoops).
Force an initial prompt.
Ordering check

C_Login() and C_Logout need to return CRYPTOKI_NOT_INITIALIZED when run too soon
Add a few more tests for incorrect ordering of login/logout
... and one more
Add missing check

All other lines in this function check the return value, except for this
one; that seems like a mistake.
Remove explicit calls to svn

There is no subversion anymore. Since git doesn't need a .git directory
*everywhere*, the export isn't strictly necessary anymore, either.
Properly delimit _all_ termios stuff

The "robot_cmd" function can only work if we actually are doing the
termios stuff, so #ifdef that out too.
