bfdd: implement passive mode
The passive mode is briefly described in the RFC 5880 Bidirectional
Forwarding Detection (BFD), Section 6.1. Overview:
> A system may take either an Active role or a Passive role in session
> initialization. A system taking the Active role MUST send BFD
> Control packets for a particular session, regardless of whether it
> has received any BFD packets for that session. A system taking the
> Passive role MUST NOT begin sending BFD packets for a particular
> session until it has received a BFD packet for that session, and thus
> has learned the remote system's discriminator value. At least one
> system MUST take the Active role (possibly both). The role that a
> system takes is specific to the application of BFD, and is outside
> the scope of this specification.
