Benjamin Walsh 1125c2b00e unified: correct comment about number of threads in phil demo
A bit of work has to be done by someone why wants to run the demo with a
different number of threads than the default.

Allan Stephens 399d0ad55a unified: Rationalize thread priority APIs
* Gets rid of k_current_priority_get(). Users can just call
  k_thread_priority_get(k_current_get()) instead.

* Declares k_thread_priority_get() in kernel.h, where it
  really belongs.

* Removes duplicate declaration of k_thread_priority_set().

Benjamin Walsh aabf74cda5 Dining philosophers demo for unified kernel.
The demo can be configured to use different object types for its
synchronization: SEMAPHORES, MUTEXES, STACKS, FIFOS and LIFOS. To
configure a specific object, set the value of FORKS to one of these.

By default, the demo uses MUTEXES.

The demo can also be configured to work with static objects or dynamic
objects. The behaviour will change depending if STATIC_OBJS is set to 0
or 1.

By default, the demo uses dynamic objects.

The demo can be configured to work with threads of the same priority or
not. If using different priorities, two threads will be cooperative
threads, and the other four will be preemtible threads; if using one
priority, there will be six preemtible threads of priority 0. This is
changed via SAME_PRIO.

By default, the demo uses different priorities.

The number of threads is set via NUM_PHIL. The demo has only been tested
with six threads. In theory it should work with less than six threads,
but not with more without making changes to the forks[] array in the
phil_obj_abstract.h header file.
