jvpp: provide more detailed exception logs (VPP-436)
Error descriptions provided in api_errno.h are never used, only error tag/name and number make it to enum vnet_api_error_t so new macro is introduced in jvpp_common.c to extract message according to error number and passed to VppCallbackException constuctor.
