0edf263139 rtems: Add system events 
System events are similar to normal events.  They offer a second set of
events.  These events are intended for internal RTEMS use and should not
be used by applications (with the exception of the transient system
event).

47a3cd8f73 score: Work area initialization API change 
The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures().  Initialization is performed with
tables of Heap_Area entries.  This allows usage of scattered memory
areas present on various small scale micro-controllers.

The sbrk() support API changes also.  The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.

9b83a66546 score: Critical fix for thread dispatching 
The changes in _Thread_Dispatch() of commits
dad36c52b8 and
d4dc7c8196 introduced a severe bug which
destroys the real-time properties of RTEMS completely.

Consider the following scenario.  We have three tasks L (lowest
priority), M (middle priority), and H (highest priority).  Now let a
thread dispatch from M to L happen.  An interrupt occurs in
_Thread_Dispatch() here:

void _Thread_Dispatch( void )
{
  [...]

post_switch:

  _ISR_Enable( level );

  <-- INTERRUPT
  <-- AFTER INTERRUPT

  _Thread_Unnest_dispatch();

  _API_extensions_Run_postswitch();
}

The interrupt event makes task H ready.  The interrupt code will see
_Thread_Dispatch_disable_level > 0 and thus doesn't perform a
_Thread_Dispatch().  Now we return to position "AFTER INTERRUPT".  This
means task L executes now although task H is ready!  Task H will execute
once someone calls _Thread_Dispatch().

f53aa8d302 rbtree: API changes. Remove rbtree control node from RBTree_Next. 
The implementation of RBTree_Next was using an awkward construction to detect
and avoid accessing the false root of the red-black tree. To deal with the
false root, RBTree_Next was comparing node parents with the control node.
Instead the false root can be detected by checking if the grandparent of a
node exists; the grandparent of the tree's true root is NULL by definition
so the root of the tree is found while walking up the tree by checking for
the non-existence of a grandparent.

This change propagates into the predecessor/successor and iterate functions.

5a4bb758c0 Filesystem: Remove per file descriptor semaphore 
The per file descriptor semaphore (field of rtems_libio_t) is unused in
RTEMS.  There is a considerable memory overhead due to that.  A
semaphore needs roughly 124 bytes which is huge compared to the
approximately 72 bytes for the file descriptor structure itself.  Device
drivers can create their own synchronization primitives in the open
handler on demand.

3b7c123c8d Filesystem: Reference counting for locations 
o A new data structure rtems_filesystem_global_location_t was
   introduced to be used for
    o the mount point location in the mount table entry,
    o the file system root location in the mount table entry,
    o the root directory location in the user environment, and
    o the current directory location in the user environment.
   During the path evaluation global start locations are obtained to
   ensure that the current file system instance will be not unmounted in
   the meantime.
 o The user environment uses now reference counting and is protected
   from concurrent access.
 o The path evaluation process was completely rewritten and simplified.
   The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation
   method.  Recursive calls in the path evaluation have been replaced
   with iteration to avoid stack overflows.  Only the evaluation of
   symbolic links is recursive.  No dynamic memory allocations and
   intermediate buffers are used in the high level path evaluation.  No
   global locks are held during the file system instance specific path
   evaluation process.
 o Recursive symbolic link evaluation is now limited by
   RTEMS_FILESYSTEM_SYMLOOP_MAX.  Applications can retrieve this value
   via sysconf().
 o The device file system (devFS) uses now no global variables and
   allocation from the workspace.  Node names are allocated from the
   heap.
 o The upper layer lseek() performs now some parameter checks.
 o The upper layer ftruncate() performs now some parameter checks.
 o unmask() is now restricted to the RWX flags and protected from
   concurrent access.
 o The fchmod_h and rmnod_h file system node handlers are now a file
   system operation.
 o The unlink_h operation has been removed.  All nodes are now destroyed
   with the rmnod_h operation.
 o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system
   operations.
 o The path evaluation and file system operations are now protected by
   per file system instance lock and unlock operations.
 o Fix and test file descriptor duplicate in fcntl().
 o New test fstests/fsnofs01.

5d44355937 PR 1991/cpukit - attr.c (really mode code) warning rework 
This PR was about a warning for no previous prototype for
rtems_interrupt_level_attribute. This method exists (like
a few others) to have real bodies for Classic API services
implemented as macros. These macros are not available from
anything but C and C++. The most explicit use was in the Ada
binding but these would be needed from assembly language
or any other non-C based language.

On top of needing a prototype, the methods were misnamed.
They were related to modes.  This renames them, moves the
file, fixes test code, etc.
