Some users might want to prefer one babel implementation over another
for various reasons. Having to compile the firmware from scratch can be
quite tedious in that case.
Instead, make the babel implementation switchable at runtime.
The implementation can be switched manually using the uci option
`babelimpl.impl.impl`, which currently is not upgrade-safe.

- refine configure/test/apply mechanics
- move dynamic includes to /tmp -> not preserved during reboot
- add custom bird procd init.d script to generate dynamic includes
-> use /tmp/bird/fff if existent (test-mode), /etc/bird/fff otherwise
- move dynamic bird2 configs to /{tmp,etc}/bird/fff
- Fix nodewatcher failing when bird is not running
Bird 2 has a few advantages over babeld. Especially the possiblity to
dynamically reload the configuration without restarting the daemon and
birds significant performance advantage make it an interesting
alternative to babeld for our firmware.
This adds the necessary implementation-specific fff-babel-bird2 package,
which allows to integrate bird2 into the fff firmware.
