Convert LOG() -> ROCP_X logging macros. (#695)

* Convert LOG() -> ROCP_X logging macros.

This patch converts the LOG() macro to the ROCP_X logging macros.
There are the following levels of logs.

Logs whos expressions are not evaluated unless the log level is enabled:

ROCP_TRACE - VLOG(2) (enabeled by env variable GLOG_v=2)
ROCP_INFO - VLOG(1) (enabeled by env variable GLOG_v=1)

Logs whos expressions are always evaluated:

ROCP_WARNING - LOG(WARNING)
ROCP_ERROR - LOG(ERROR)
ROCP_FATAL - LOG(FATAL)
ROCP_DFATAL - DLOG(FATAL) (only fatal in debug mode)
