fix __LINE__ issues

#262

I'd like the problem described here resolved for all affected tests. It's one of the few things remaining preventing my compiler from hitting 100% test compliance. Thanks.

bslmt_readerwriterlockassert.t.cpp
bdls_testutil.t.cpp
ball_log.t.cpp
ball_logthrottle.t.cpp

are going to be addressed by me in a separate pull request. Alisdair in the meantime will either fix the remaining "old style" names or not in #262, it is up to him, as I have looked at the whole file and it already has both style constants. :( Which means this change set did not introduce an inconsistency.
