The functions
o rtems_bdbuf_get(),
o rtems_bdbuf_read(),
o rtems_bdbuf_syncdev(), and
o rtems_bdbuf_purge_dev(),
use now the disk device instead of the device identifier. This makes
bdbuf independent of rtems_disk_obtain() and rtems_disk_release(). It
is the responsiblity of the file system to obtain the disk device. This
also reduces the overhead to get a buffer.
The key for the AVL tree uses now the disk device instead of the device
identifier. The pointer is interpreted as an unsigned integer. This
reduces the memory overhead and makes the comparison operation a bit
faster.
Removed function rtems_bdbuf_purge_major(). This function was too
destructive and could have unpredictable side effects.

* libblock/src/diskdevs.c: rtems_disk_next() will now implicitly
obtain the returned disk.
* libblock/include/rtems/diskdevs.h: Documentation.
- Fixed printf() formats. New structure for waiters synchronization. Added BDBUF_INVALID_DEV define. New error handling in rtems_bdbuf_init().
- Release disk in case of an error.

* libblock/include/rtems/blkdev.h: New request code
RTEMS_BLKIO_DELETED.
* libblock/src/diskdevs.c: Major rewrite. Changed the way disks are
deleted. Disks will be now deleted if they are not in use or upon
last release. The IO control handler will be invoked if a physical
disk is deleted with the RTEMS_BLKIO_DELETED request code. Logical
disks increase now the usage count of the associated physical disk.

first parameter instead of the physical device number.
