libbb: add generic "fd polling and I/O" loop, use it in telnetd
We do it, badly, in many places. Better to use one robust implementation.
Can be buggy yet.
Initial use is in a rather old, rarely used tech: telnet.
The I/O in telnetd should be fully non-blocking now,
including pty delays handling.
Several bugs in telnetd handling of IACs are fixed.
