d5e073cde7 score: Allow interrupts during thread dispatch 
Use a processor-specific interrupt frame during context switches in case
the executing thread is longer executes on the processor and the heir
thread is about to start execution.  During this period we must not use
a thread stack for interrupt processing.

Update #2809.

d78d5294cd score: Add and use _Thread_Dispatch_direct() 
This function is useful for operations which synchronously block, e.g.
self restart, self deletion, yield, sleep.  It helps to detect if these
operations are called in the wrong context.  Since the thread dispatch
necessary indicator is not used, this is more robust in some SMP
situations.

Update #2751.

04bd261726 arm: Use TPIDRPRW for current per-CPU control 
Use the previously unused TPIDRPRW register to get the per-CPU control
of the current processor.  This avoids instructions in
GET_SELF_CPU_CONTROL which are not available in Thumb mode.

38a1449fd4 powerpc: Add _CPU_Get_current_per_CPU_control() 
Add _CPU_Get_current_per_CPU_control() on SMP configurations.  Use SPRG0
for the current per-CPU control.  This reduces the code size by three
instructions and is slightly faster.

e6107854b2 score: Rename _Scheduler_Assignments 
Rename _Scheduler_Assignments into _Scheduler_Initial_assignments to

assignment.

f20dfa8fcd score: Avoid _Scheduler_Get_by_CPU_index( 0 )

Sebastian Huber
2612a0bf5b score: Simplify _Scheduler_Get_by_id() 
Avoid dead code in non-SMP configurations.  Return scheduler identifier
independent of the current processor count of the scheduler via
rtems_scheduler_ident(), since this value may change during run-time.
Check the processor count in _Scheduler_Set() under scheduler lock
protection.

2f5ac5b507 rtems: Fix rtems_task_create() scheduler selection 
Use the home scheduler of the executing thread for the created thread.
This is in line with pthread_create().  Using the current processor may
pick up an unexpected scheduler in case of a temporary migration, e.g.
due to locking protocols.

eb98dd49bc score: Inline some SMP lock operations by default 
The SMP ticket lock release turned out to be suitable for inlining, e.g.
a hand full of instructions, no branches.

The changes in the screen files do not reflect the changes due to this
commit.  However, they are now up to date.  Obtained on a T4240 running
at 1.5GHz using GCC 7.0.0 20161108..

df63fbd1ac score: Add <rtems/score/cpuimpl.h>

e7ab43d46f score: Use non-inline thread queue lock ops 
This reduces the code size and helps to reduce the amount of testing.
Hot paths can use the _Thread_queue_Queue_acquire_critical() and
_Thread_queue_Queue_release_critical() functions which are still inline.
