Merge IETF and Openconfig to use SCVPP

scvpp should eventually be the only interface with VAPI and should not
depend on sysrepo.
-All sysrepo error codes in scvpp codes have been changed for errno error
codes. scvpp might eventually needs its own error codes.
-All log messages in scvpp have been removed as error codes are the only
way of reporting failures in a library.
-Move VAPI symbol definition to SCVPP.

In scvpp, unused maccros SC_VPP_VAPI_RECV and SC_REGISTER_RPC_EVT_HANDLER have
been removed.

Regarding plugins update:
-Use Openconfig way to convert interface name to interface index.
-Use Openconfig way to enable/disable an interface.
-Use Openconfig way of configuring interface IPs but use more arguments like
IETF.
-Use Openconfig way of adding a new route.
-Use Openconfig way of dumping an IP.
-Use common interface dump operation for get_name and get_id.
-Delete unused create loopback
