gdb-python: Update so 'rtems task' lists the classic tasks.

Browse Source 
This is a first pass at cleaning up the support. To use:

 $ waf configure --prefix=$HOME/development/rtems/4.11
 $ waf build install

Start GDB and break at Init:

 (gdb) py import rtems
 (gdb) rtems task

will list the classic API tasks.
