zebra: zebra crash for zapi stream
Issue:
If static route is created with a BGP route as nexthop, which
recursively resolves over 512 ECMP v6 nexthops, zapi nexthop encode
fails, as there is not enough memory allocated for stream. This causes
assert/core dump in zebra. Right now we allocate fixed memory
of ZEBRA_MAX_PACKET_SIZ size.
Fix:
1)Dynamically calculate required memory size for the stream
2)try to optimize memory usage
Testing:
No crash happens anymore with the fix
