Final fixes for Memory_used

Browse Source 
- Change some static variables to dynamic to ensure that we don't do any memory
  allocations before server starts or stops
- Print more memory information on SIGHUP. Fixed output.
- Write out if memory was lost if run with --debug-at-exit
- Fixed wrong #ifdef in sql_cache.cc
