Changeset 3162858 in rtems-tools for tools/gdb

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

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.
