Update(s) since 2.0.147:
  - Updated CheckerGccPlugins with the following:
    * Various cleanups/fixes. Updates for gcc13.
    * Remove code for ctor/dtor attribute workaround that was needed for gcc versions prior to 10.
    * We special-case a number of methods, allowing them to be overridden with inconsistent threading attributes.  This is used for things like the Gaudi initialize() and finalize() methods. Change to get this list from the configuration file rather than a hard-coded list.
    * Add new warning: passing a pointer member from a const member function to a non-const pointer argument.

Update(s) since 2.0.140:
  - Updated CheckerGccPlugins with the following:
    * Skip checking of _rootcint.cxx files.
    * Replace the hardcoded list of directory names for code that is to be considered thread-safe with a configuration parameter.
    * For warnings about calling non-const methods via a pointer member from a const method, realize that unique_ptr::get() also returns the pointer.  Treat it like operator->.  Also fix an issue with suppressing this warning for unique_ptr.
    * Don't warn about overriding the non-const execute() method of Algorithm with a non-thread-safe method.
    * Fix warning suppression for ctor calls.
    * Remove references to ATLAS_CTORDOR_NOT_THREAD_SAFE workaround.
