bird/sysdep/unix/krt.Y
Martin Mares 7de45ba4a0 Kernel route syncer supports multiple tables.
The changes are just too extensive for lazy me to list them
there, but see the comment at the top of sysdep/unix/krt.c.
The code got a bit more ifdeffy than I'd like, though.

Also fixed a bunch of FIXME's and added a couple of others. :)
