A change in OSPF and RIP interface patterns.

Browse source 
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };
