Uniprocessor Tests in SMP Configuration

Hello,

I would do the following.

1. Implement the thread deletion on SMP.  I will work on this after the 
profiling.

http://www.rtems.org/wiki/index.php/SMP#Thread_Delete.2FRestart

2. Use alternatives to task variables for all RTEMS support components, 
e.g. the file system environment.  Here we can use __getreent() for 
example with

struct S {
   struct _reent reent;
   rtems_user_env_t env;
}

POSIX keys should be moved outside the RTEMS_POSIX_API scope.

3. Disable the task variables via pre-processor on SMP and remove the 
run-time check.

4. Add condition variables to the Classic API.

5. Use alternatives to disabled preemption for all RTEMS support 
components, e.g. bdbuf.

6. Disable RTEMS_PREEMT via pre-processor on SMP and remove the run-time 
check.

We (= embedded brains) have currently only a budget for 1.
