Filter: Instruction codes named as enum
...
The two-letter instructions were quite messy but they could be easily
read from memory dumps. Now GDB (since 2012) supports pretty printing
enum values and GCC checks the switch construction for missing enum
values so we are converting the nice two-byte values to enums.
Anyway, the enum still keeps the old two-byte values to be able to read
the instruction codes even without GDB from plain memory dump.

Filter: Allow silent filter execution
...
A filter should log messages only if executed explicitly (e.g., during
route export or route import). When a filter is executed for technical
reasons (e.g., to establish whether a route was exported before), it
should run silently.

Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.
Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).
From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

RPKI protocol with one cache server per protocol

The RPKI protocol (RFC 6810) using the RTRLib
(http://rpki.realmv6.org/ ) that is integrated inside
the BIRD's code.
Implemeted transports are:
- unprotected transport over TCP
- secure transport over SSHv2
Example configuration of bird.conf:
...
roa4 table r4;
roa6 table r6;
protocol rpki {
debug all;
# Import both IPv4 and IPv6 ROAs
roa4 { table r4; };
roa6 { table r6; };
# Set cache server (validator) address,
# overwrite default port 323
remote "rpki-validator.realmv6.org" port 8282;
# Overwrite default time intervals
retry 10; # Default 600 seconds
refresh 60; # Default 3600 seconds
expire 600; # Default 7200 seconds
}
protocol rpki {
debug all;
# Import only IPv4 routes
roa4 { table r4; };
# Set cache server address to localhost,
# use default ports tcp => 323 or ssh => 22
remote 127.0.0.1;
# Use SSH transport instead of unprotected transport over TCP
