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.
* libcsupport/include/rtems/libio_.h: Declare
rtems_filesystem_mount_table_control.
* libcsupport/include/rtems/libio.h: Removed
rtems_filesystem_table_first(), rtems_filesystem_table_next() and
rtems_filesystem_table_node_t declarations. Declare
rtems_per_filesystem_routine, rtems_filesystem_iterate() and
rtems_filesystem_get_mount_handler().
* libcsupport/src/mount.c: Added rtems_filesystem_mounts_first() and
rtems_filesystem_mounts_next(). Simplify mount(). Removed
rtems_filesystem_mount_table_control_init. Use
rtems_filesystem_get_mount_handler().
* libcsupport/src/mount-mgr.c: Removed rtems_filesystem_mounts_first() and
rtems_filesystem_mounts_next(). Added rtems_filesystem_iterate() and
rtems_filesystem_get_mount_handler(). Use rtems_libio_lock() and
rtems_libio_unlock();
* sapi/include/confdefs.h, libmisc/shell/main_mount.c: Update for
mount API changes.
* libcsupport/Makefile.am: Add mount-mgr.c.
* libcsupport/src/mount-mgr.c: New.
* include/rtems/fs.h: Added rtems_filesystem_location_mount.
* libcsupport/include/rtems/libio.h, libcsupport/src/mount.c: New
mount interface. It is similar to Linux.
* libcsupport/include/rtems/libio_.h: Remove the
init_fs_mount_table call.
* libcsupport/src/base_fs.c: Remove init_fs_mount_table_call. Use
the new mount call. Remove setting the root node in the global
pathloc. Mount does this now.
* libcsupport/src/privateenv.c: Remove the hack to set the root
mount table entry in the environment.
* libcsupport/src/unmount.cL Free the target string.
* libblock/src/bdpart-mount.c: New mount API.

libmisc/shell/main_mount_msdos.c, libmisc/shell/main_mount_rfs.c,
libmisc/shell/main_mount_tftp.c: Removed.
* 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.

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/confdefs.h, score/Makefile.am,
score/include/rtems/score/thread.h: Only instantiate
_Thread_Idle_body() if it is going ot be used.
* score/src/threadidlebody.c: Removed.
* libcsupport/src/malloc_boundary.c: This is currently non-funcitonal.
Do not build it when doing coverage until it works again.
* sapi/include/confdefs.h: Address linking errors when building for
configuration.
* posix/include/rtems/posix/config.h, posix/src/mqueue.c,
sapi/include/confdefs.h: Add configuration of posix message queue
file descriptors as separate entity.
* libmisc/dummy/dummy-networking.c: New.
* libmisc/dummy/dummy.c, libmisc/Makefile.am: Move
trhe networking configuration into a separate file so
configuration varations do not cause conflicts.
* score/inline/rtems/score/object.inl,
score/include/rtems/score/object.h: Remove warnings.
* score/inline/rtems/score/object.inl: Add _Chain_First,
_Chain_Last, _Chain_Mext, and _Chain_Previous.

rtems_chain_last, rtems_chain_mext, and rtems_chain_previous.
* libblock/include/rtems/diskdevs.h: Remove the bdbuf pool id and
block_size_log2. Add media_block_size.
* libblock/src/diskdevs.c: Remove size restrictions on block
size. Add media block size initialisation. Remove comment to clean
up the bdbuf cache.
* libblock/src/blkdev.c: Remove references to
block_size_log2. Allow any block size.
* libblock/include/rtems/bdbuf.h, libblock/src/bdbuf.c: Remove all
references to pools and make the cache handle demand driver
variable buffer size allocation. Added worker threads support the
swapout task.
* sapi/include/confdefs.h: Updated the bdbuf configutation.
* libcsupport/Makefile.am, libcsupport/preinstall.am,
sapi/include/confdefs.h: Add configuration and basic device driver
ver definition for frame buffer device.
* libcsupport/include/rtems/framebuffer.h: New file.
* sapi/include/confdefs.h, libblock/include/rtems/bdbuf.h: Changed
type of rtems_bdbuf_pool_configuration_size to size_t.

libblock/include/rtems/diskdevs.h, libblock/src/bdbuf.c,
libblock/src/blkdev.c, libblock/src/diskdevs.c: Buffer pool
allocation is now cache aligned. The cache functions are
currently not available on all platforms so the cache line size is
fixed to 32 bytes for now. Changed various integer types which
refer to block sizes, numbers and indexes. Fixed logical block
indexes in buffer get and read function. It is now possible to
delete logical disks. Modified documentation
* sapi/include/confdefs.h: Add a prototype for Init with C linkage
and define Init task command line arguments if confdefs.h provides
an Init entry point.

score/src/wkspace.c: Eliminate pointers to API configuration tables
in the main configuration table. Reference the main configuration
table and the API configuration tables directly using the confdefs.h
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.
* sapi/include/confdefs.h: Add disable of pipes by default since they
use resources which are otherwise not accounted for. Eventually the
resources will have to be properly configured.
PR 1341/cpukit
* sapi/include/confdefs.h: The following macros were missing
the _Configure_From_workspace() wrapper on their size estimate:
+ CONFIGURE_INTERRUPT_STACK_MEMORY
+ CONFIGURE_MEMORY_PER_TASK_FOR_CLASSIC_API
+ CONFIGURE_INTERRUPT_VECTOR_TABLE
+ CONFIGURE_MEMORY_FOR_STATIC_EXTENSIONS
In addition, there was a duplicate definition of
CONFIGURE_MEMORY_PER_TASK_FOR_CLASSIC_API.
