* libblock/include/rtems/diskdevs.h: Documentation. Added field to
rtems_disk_device.
* 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.
* libblock/include/rtems/ramdisk.h: Documentation.
* libblock/src/ramdisk-driver.c: Compile trace support conditionally.
