// Change log
//
// 1  mf  5/12/06   In ctor, MessageDrop::debugEnabled is set to a
//          sensible value in case action happens before modules
//          are entered.  If any modules enable debugs, such
//          LogDebug messages are not immediately discarded
//          (though they might be filtered at the server side).
//
// 2  mf  5/27/06   In preEventProcessing, change the syntax for
//          runEvent from 1/23 to Run: 1 Event: 23
//
// 3 mf   6/27/06   PreModuleConstruction and PreSourceConstruction get
//          correct module name
//
// 4 mf   6/27/06   Between events the run/event is previous one
//
// 5  mf  3/30/07   Support for --jobreport option
//
// 6 mf   6/6/07    Remove the catches for forgiveness of tracked
//          parameters
//
// 7 mf   6/19/07   Support for --jobreport option
//
// 8 wmtan 6/25/07  Enable suppression for sources, just as for modules
//
// 9 mf   7/25/07   Modify names of the MessageLoggerQ methods, eg MLqLOG
//
//10 mf   6/18/07   Insert into the PostEndJob a possible SummarizeInJobReport
//
//11 mf   3/18/09   Fix wrong-sense test establishing anyDebugEnabled_
//
//12 mf   5/19/09   MessageService PSet Validation
//
//13 mf   5/26/09   Get parameters without throwing since validation
//          will point out any problems and throw at that point
//
//14 mf   7/1/09    Establish module name and set up enables/suppresses
//          for all possible calls supplying module descriptor
//
//14 mf   7/1/09    Establish pseudo-module name and set up
//          enables/suppresses for other calls from framework
//15 mf   9/8/09    Clean up erroneous assignments of some callbacks
//          for specific watch routines (eg PreXYZ called postXYZ)
//
//16 mf   9/8/09    Eliminate caching by descriptor address during ctor
//          phases (since addresses are not yet permanent then)
//
//17 mf   11/2/10   Move preparation of module out to MessageDrop methods
//   crj        which will only be called if a message is actually
//          issued.  Caching of the work is done within MessageDrop
//          so that case of many messages in a module is still fast.
//
//18 mf   11/2/10   Eliminated curr_module, since it was only being used
//          as a local variable for preparation of name (never
//          used to transfer info between functions) and change
//          17 obviates its need.
//
// 19 mf 11/30/10   Add a messageDrop->snapshot() when establishing
//    crj       module ctors, to cure bug 75836.
//
// 20 fwyzard 7/06/11   Add support fro dropping LogError messages
//                      on a per-module basis (needed at HLT)
