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> 
The aim of this file is to encapsulate CPU port implementation details.
This helps to hide implementation details from <rtems.h> which
indirectly includes <rtems/score/cpu.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.
