2008-07-29 Chris Johns <chrisj@rtems.org>

	* libblock/Makefile.am: Removed src/show_bdbuf.c.

	* libblock/src/show_bdbuf.c: Removed.

	* libblock/include/rtems/bdbuf.h, cpukit/libblock/src/bdbuf.c:
	Rewritten the bdbuf code. Remove pre-emption disable, score
	access, fixed many bugs and increased performance.

	* libblock/include/rtems/blkdev.h: Added
	RTEMS_BLKDEV_CAPABILITIES block device request. Cleaned up
	comments. Added block and user fields to the sg buffer
	request. Move to rtems_* namespace.

	* libblock/include/rtems/diskdevs.h,
	cpukit/libblock/src/diskdevs.c: Move to rtems_* namespace. Add a
	capabilities field for drivers. Change rtems_disk_lookup to
	rtems_disk_obtain to match the release call. You do not lookup and
	release a disk, you obtain and release a disk.

	* libblock/include/rtems/ide_part_table.h,
	libblock/include/rtems/ramdisk.h, libblock/src/ide_part_table.c:
	Move to rtems_* namespace.

	* libblock/include/rtems/nvdisk.h: Formatting change.

	* libblock/src/blkdev.c: Move to rtems_* namespace. Change
	rtems_disk_lookup to rtems_disk_obtain

	* libblock/src/flashdisk.c: Move to rtems_* namespace. Use the new
	support for the block number in the scatter/grather request
	struct. This allows non-continuous buffer requests for those
	drivers that can support increasing performance.

	* libblock/src/nvdisk.c: Move to rtems_* namespace. Removed
	warnings. Added better error checking. Fixed some comments.

	* libblock/src/ramdisk.c: Move to rtems_* namespace. Added some
	trace functions to help debugging upper layers. Use the new
	support for the block number in the scatter/grather request
	struct. This allows non-continuous buffer requests for those
	drivers that can support increasing performance.

	* libfs/src/dosfs/fat.c, libfs/src/dosfs/fat.h: Use new chains
	API. Removed temporary hack and changed
	set_errno_and_return_minus_one to
	rtems_set_errno_and_return_minus_one. Move fat_buf_access from
	header and stopped it being inlined. Updated to libblock changes.

	* libfs/src/dosfs/fat_fat_operations.c,
	libfs/src/dosfs/fat_file.c, libfs/src/dosfs/msdos_create.c,
	libfs/src/dosfs/msdos_dir.c, libfs/src/dosfs/msdos_eval.c,
	libfs/src/dosfs/msdos_file.c, libfs/src/dosfs/msdos_format.c,
	libfs/src/dosfs/msdos_free.c, libfs/src/dosfs/msdos_initsupp.c,
	libfs/src/dosfs/msdos_misc.c, libfs/src/dosfs/msdos_mknod.c: Use
	new chains API. Removed temporary hack and changed
	set_errno_and_return_minus_one to
	rtems_set_errno_and_return_minus_one. Updated to libblock changes.

	* libmisc/Makefile.am: Add new ls and rm command files.

	* libmisc/shell/cmp-ls.c, libmisc/shell/extern-ls.h,
	libmisc/shell/filemode.c, libmisc/shell/print-ls.c,
	libmisc/shell/pwcache.c, libmisc/shell/utils-ls.c,
	libmisc/shell/vis.c, shell/vis.h: New.

	* libmisc/shell/extern-cp.h, libmisc/shell/main_cp.c,
	libmisc/shell/utils-cp.c: Fixed the usage call bug.

	* libmisc/shell/main_blksync.c: Updated to the new block IO ioctl
	command.

	* libmisc/shell/main_ls.c, libmisc/shell/main_rm.c: Updated to BSD
	commands with more features.

	* score/src/coremutex.c: Fix the strick order mutex code.

	* libmisc/shell/shell.c: Change shell tasks mode to be timeslice
	and no ASR.

	* sapi/include/confdefs.h: Change ata_driver_task_priority to
	rtems_ata_driver_task_priority. Add the new BD buf cache
	parameters with defaults.

	* score/src/interr.c: Do not return if the CPU halt call returns.
