bgpd: add flowspec feature
This work is derived from a work done by China-Telecom.
That initial work can be found in [0].
As the gap between frr and quagga is important, a reworks has been
done in the meantime.
The initial work consists of bringing the following:
- Bringing the client side of flowspec.
- the enhancement of address-family ipv4/ipv6 flowspec
- partial data path handling at reception has been prepared
- the support for ipv4 flowspec or ipv6 flowspec in BGP open messages,
and the internals of BGP has been done.
- the memory contexts necessary for flowspec has been provisioned
In addition to this work, the following has been done:
- the complement of adaptation for FS safi in bgp code
- the code checkstyle has been reworked so as to match frr checkstyle
- the processing of IPv6 FS NLRI is prevented
- the processing of FS NLRI is stopped ( temporary)
