* 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.
* libblock/include/rtems/ramdisk.h: Documentation.
* libblock/src/ramdisk-driver.c: Compile trace support conditionally.
control function. The IO control handler takes now the disk device as
first parameter instead of the physical device number.

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
