Ondrej Zajicek e29f134ad9 BFD: Fix build when BFD is disabled
Move bfd_opts grammar inside BFD parser code to avoid dependences between
nest and BFD grammars, which breaks when BFD build is disabled.

Add dummy bfd_opts grammar rule, so protocols can use this nonterminal
even with BFD disabled.

Thanks to Yuri Honegger for the bugreport.
