message:
   CMakeLists.txt files cleanup.
  
  - remove SAFEMALLOC and SAFE_MUTEX definitions that were
  present in *each* CMakeLists.txt. Instead, put them into top level
  MakeLists.txt, but disable on Windows, because
  
  a) SAFEMALLOC does not add any functionality that is not already
  present in Debug C runtime ( and 2 safe malloc one on top of the other
  only unnecessarily slows down the server)
  
  b)SAFE_MUTEX does not work on Windows  and have been
  explicitely  disabled on Windows with #undef previously.  Fortunately,
  ntdll does  pretty good  job identifying l problems with  CRITICAL_SECTIONs.
  (DebugBreak()s on using uninited critical section, unlocking unowned
  critical section)
  
  -Remove occationally used -D_DEBUG (added by compiler
  anyway)
  
  -Remove MAP file generation, it became  obsolete .
  There are many ways to get callstack  of a crash now, with stacktrace in 
  error log , minidump etc
