Add RTEMS Scheduler Simulator.
* sapi/include/confdefs.h: This adds some simple conditional
logic to disable portions of the configuration that are NOT supported
when configuring an RTEMS instance for use with a Scheduler Simulator
instance.
PR 1718/cpukit
* sapi/include/confdefs.h: POSIX threads are allocated twice the
minimum stack space by default. confdefs.h only accounts for one
minimum -- not the 2x factor.

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.
* score/include/rtems/score/prioritybitmap.h,

* libcsupport/include/rtems/libio_.h: Declare
rtems_filesystem_mount_table_control.

* libfs/src/devfs/devfs_eval.c: Local include of extern ops.
* libfs/src/nfsclient/src/nfs.c: New mount API. Removed the mount
me call and fixed the initialisation to happen when mounting.

* libmisc/shell/main_mount.c: Use the new mount API. Also access
the file system table for the file system types.
* libnetworking/lib/tftpDriver.c: Updated to the new mount
API. Fixed to allow mounting from any mount point. Also can now
have more than file system mounted.
* sapi/include/confdefs.h: Add file system configuration support.
* sapi/include/confdefs.h: New define CONFIGURE_SEMAPHORES for the
overall count of required semaphores. New define
CONFIGURE_LIBBLOCK_SEMAPHORES for the count of required disk and bdbuf
semaphores.
* libblock/src/ramdisk-config.c, sapi/include/confdefs.h:
CONFIGURE_DISABLE_CLASSIC_NOTEPADS is typo of
CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS. Fix it.
* sapi/include/rtems/config.h: Fixed typos (wrong case) in macro
expansion for

statvfs handler to NULL.
* include/rtems/fs.h: Add a second node access field for the RFS
file system to hold a directory offset while the existing field
holds the inode number. This save a rescan of the directory when
working with directories.
* libblock/include/rtems/bdbuf.h: Added references and user fields
to the buffer descriptor.
* libblock/src/bdbuf.c: Added dynamic buffer support for different
block sizes. Fixed a number of bugs.

libblock/src/ramdisk.c: Updated the drivers to handle variable
block sizes.
* libfs/src/dosfs/fat.c, libfs/src/dosfs/fat.h: Release any
buffers when an error occurs. The FAT buffer layer hangs onto a
single buffer while mounted. This should be fixed.

rtems_chain_is_node_off_chain, and rtems_chain_previous.

* sapi/src/ioregisterdriver.c: Reowork so this is a context switch
disable critical section not interrupt disable critical section.
Hopefully eliminated dead code which showed up in coverage runs.
* sapi/include/rtems/io.h, sapi/src/ioregisterdriver.c: Documenation.
rtems_io_lookup_name() is now deprecated. Added
rtems_io_driver_io_error(). rtems_io_register_driver() is now
thread-safe.

score/include/rtems/score/thread.h: Only instantiate
_Thread_Idle_body() if it is going ot be used.
