EX-4141 lipe: keepalive message from ofd_access_log_reader

Lamigo checks ofd_access_log_reader for keepalive message
feature availability. Start ofd_access_log_reader with keepalive
message option if it is available.
Added tests for lamigo and ofd_access_log_reader to
test keepalive message feature
Fixed a bug when trace file is opened.
Moved FATAL, ERROR, DEBUG macros to include and
Used FATAL macro wherever possible
