of filter/config.Y. Bird now compiles even if you disable RIP.
Removed RTA and IMPOSSIBLE tokens (unused).
Removed superfluous comment in filter.h.
I've tried to do my best, but Pavel, please check these changes.
o Parsing of interface patterns moved to generic code,
introduced this_ipatt which works similarly to this_iface.
o Interface patterns now support selection by both interface
names and primary IP addresses.
o Proto `direct' updated.
o RIP updated as well, it also seems the memory corruption
bug there is gone.
- cfg_strcpy() -> cfg_strdup()
- mempool -> linpool, mp_* -> lp_* [to avoid confusion with memblock, mb_*]
Anyway, it might be better to stop ranting about names and do some *real* work.
