On old compilers CPP_NOTICE should be a macro evaluating to an empty
statement, instead of being undefined.

EVPN ND ext community support NA flag R-bit, to have proxy ND.
Set R-bit in EVPN NA if a given router is default gateway or there is a
local
router attached, which can be determine based on local neighbor entry.
Implement BGP ext community attribute to generate and parse R-bit and
pass along zebra to program neigh entry in kernel.
Upon receiving MAC/IP update with community type 0x06 and sub_type 0x08,
pass the R-bit to zebra to program neigh entry.
Set NTF_ROUTER in neigh entry and inform kernel to do proxy NA for EVPN.

those flags are moved to common pbr.h header file.

If your daemon does not need any special privileges
and you are compiling with HAVE_CAPABILIES, the
zprivs->change pointer will end up NULL due
to the way zprivs_caps_init. So as a check
let's add a NULL check for zprivs->change
and set it to a function that will do nothing.
This change prevents a crash if you raise privileges
when your daemon needs no special privileges.
