77c5ddd496 smptests/smpmrsp01: Fix task delete race condition 
Do not supsend self while waiting for termination since the
rtems_task_delete() may take place while the rtems_task_suspend() waits
for the Giant lock preventing delivery of the inter-processor interrupt.
The result is a suspended and terminated thread (this is a valid state,
but leads in this case to a test failure).

864d3475a5 smp: Fix timeout for MrsP semaphores 
The previous timeout handling was flawed.  In case a waiting thread
helped out the owner could use the scheduler node indefinitely long.
Update the resource tree in _MRSP_Timeout() to avoid this issue.

Bug reported by Luca Bonato.

5bd822a779 smp: Fix scheduler helping protocol 
Ensure that scheduler nodes in the SCHEDULER_HELP_ACTIVE_OWNER or
SCHEDULER_HELP_ACTIVE_RIVAL helping state are always
SCHEDULER_SMP_NODE_READY or SCHEDULER_SMP_NODE_SCHEDULED to ensure the
MrsP protocol properties.

cceb19f4e5 smp: Fix scheduler helping protocol 
New test case for smptests/smpmrsp01.

Fix _Scheduler_Block_node() in case the node is in the
SCHEDULER_HELP_ACTIVE_RIVAL helping state.  For example a
rtems_task_suspend() on a task waiting for a MrsP semaphore.

Fix _Scheduler_Unblock_node() in case the node is in the
SCHEDULER_SMP_NODE_READY state.  For example a rtems_task_resume() on a
task owning or waiting for a MrsP semaphore.

8568341d69 score: Need for help indicator for scheduler ops 
Return a thread in need for help for the following scheduler operations

- unblock,
- change priority, and
- yield.

A thread in need for help is a thread that encounters a scheduler state
change from scheduled to ready or a thread that cannot be scheduled in
an unblock operation.  Such a thread can ask threads which depend on
resources owned by this thread for help.
