Because the prefix structure may include or not evpn sub structure, then
HAVE_EVPN compilation define is also used in prefix.c, because it
references the sub field evpn of prefix structure.

The requirement from draft-ietf-bess-evpn-prefix-advertisement-03
mentions that the Eth-Tag ID, IP Prefix Length and IP Prefix will be
part of the route key used by BGP. The ip prefix length is then appended
to the evpn_addr. In addition to this, the ethernet tag ID is reused.

Extend the prefix data structure to allow for basic support for EVPN type-3
and type-2 routes.
Note: This may be revised in future.

To support EVPN, a new AFI and SAFI value are defined here.
For internal processing, two other values are used. Those values will
be used to reach RIB entries by using internal afi and safi values
as indexes. This commit is using naming convention for using EVPN.
External value exchanged in BGP packets is called of with
IANA_ presence in macro, while internal value will not have _IANA_
presence.

Merge the parsed graph into the existing one as a separate step. This
makes it possible to merge identical subgraphs, which is used e.g. in
bgpd for <A.B.C.D|X:X::X:X|WORD> neighbor names.

Like config_write(), this should use rename(), even though atomicity is

sync() has a HUGE impact on systems that perform actual I/O, i.e. real
servers...
Also, we were leaking a fd on each config write ever since

The code was making the correct assumption
that the v4 and v6 addresses start in the
same spot in memory and since we were looking
at a v6 prefix it would just work. This
causes distress in SA systems, so let's just
make it happy.

It is possible if the hostname is > 32
characters that we would just overrun the

the hostname string to 31 characters (to allow for NULL)

was_stdio was never set up with a 'correct'

In the case where we are using select as
the operator *and* we call
funcname_thread_add_read_write *and* the
fd is already set, we would overwrite
the read/write direction to always be READ.
Clearly this was a bad idea.

The cli could be reduced for v4 and v6 code
paths into 1 function. Additionally the v6
code path had a SA issue found where it
"theoratically" could have caused a null
