SMP support. This adds an allocated array of the Per_CPU structures
to support multiple cpus vs a single instance of the structure which
is still used if SMP support is disabled. Configuration support is
also added to explicitly enable or disable SMP. But SMP can only be
enabled for the CPUs which will support it initially -- SPARC and
i386. With the stub BSP support, a BSP can be run as a single core
SMP system from an RTEMS data structure standpoint.

Refactoring of priority handling, to isolate the bitmap
implementation of priorities in the supercore so that priority
management is a little more modular. This change is in anticipation
of scheduler implementations that can select how they manage tracking
priority levels / finding the highest priority ready task. Note that
most of the changes here are simple renaming, to clarify the use of
the bitmap-based priority management.

all tests to run on SPARC with 16-bit Ids. This required ensuring
that all POSIX and compilering binding code makes a distinction
between the public Id type (e.g. pthread_t, etc.) and the RTEMS
Object_Id type. All POSIX Object Get routines should not take the
POSIX Id type as the argument. Sixteen bit RTEMS Ids should be placed
into the 32-bits reserved by the POSIX API type in a uniform manner
now. This removed all assumptions that the external Id types in POSIX
and ITRON are the same as the internal Object Id type.

version rather than obtaining a pointer to it. This eliminated some
variables, a potential fatal error, some unnecessary default
configuration structures. Overall, about a 4.5% reduction in the code
size for minimum and hello on the SPARC.
reduce size of data area.
IMFS: Fixed creation of symbolic links to avoid a compiler warning.

* sapi/include/rtems/init.h, sapi/src/exinit.c: Refactored and renamed
initialization routines to rtems_initialize_data_structures,
rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.

This should help eliminate weird casts between u32 and pointers in
various places. The APIs now have to explicitly call _u32 or _string
versions of helper routines. This should also simplify things and
eliminate the need for ugly casts in some cases.
