[commit/Ada] Remove the "Running" state

[Joel Brobecker <brobecker at adacore dot com>]

Some users reported that they found that a task state shown as "Running"
was confusing. Since this was not a real state as provided by the
runtime, and since the implementation of this feature was bogus
(if you switch to another "runnable" task, it becomes "running"),
we decided to remove this state entirely, and just display what
the runtime tells us about the task.

        * ada-tasks.c (short_task_info): Eliminate the "Running" task state.

gdb/doc/
2009-03-31  Joel Brobecker  <brobecker@adacore.com>

        * gdb.texinfo (Ada Tasks): Remove the documentation about
        the "Running" state, as this state has been eliminated.
        Now all runnable tasks are shown as "Runnable".

Tested on x86_64-linux and checked in.
