Better selection of link-local NLRI addresses, at least for our own
...
address. Need to do it better for the other neighbors -- the current
solution works only if they use the standard 64+64 global addresses
and the interface identifier in lower 64 bits is the same as for the
link-scope addresses.

Cleanup of configuration.
...
o Use `expr' instead of `NUM' and `ipa' instead of `IPA',
so that defined symbols work everywhere.
o `define' now accepts both numbers and IP addresses.
o Renamed `ipa' in filters to `fipa'.
Pavel, please update filters to accept define'd symbols as well.

Please try compiling your code with --enable-warnings to see them. (The
unused parameter warnings are usually bogus, the unused variable ones
are very useful, but gcc is unable to control them separately.)
