Rusty Russell 48522f3e9e common: don't hang up when we receive a warning. 
We were allowed to, but the spec removed that.  So we handle warnings
differently from errors now.

This also means the LND "internal error" workaround is done in
lightningd (we still disconnect, but we don't want to close channel).

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Protocol: we no longer disconnect every time we receive a warning message.
