1fc2e960ce libblock: Add RTEMS_BDBUF_USE_PTHREAD 
Use the PTHREAD mutexes and condition variables if available.  This
helps on SMP configurations to avoid the home grown condition variables
via disabled preemption.

9f0a68ce5a libblock: Block device transfer request API change 
Add and use rtems_blkdev_request_done().  Block device transfer requests
must signal the completion status now with rtems_blkdev_request_done().
The return value of the block device IO control will be ignored for
transfer requests.

The first parameter of rtems_blkdev_request_cb is now the transfer
request structure.

Renamed rtems_blkdev_request::req_done to rtems_blkdev_request::done to
break third party drivers at compile time, otherwise this API change
would result in runtime errors.

9dffa384e1 libblock: rtems_bdbuf_set_block_size() API change 
The set block size must synchronize and purge the disk to avoid an
inconsistent cache state and data corruption.  The synchronization is
optional depending on the new sync parameter.  In some contexts a
synchronization must not be performed, e.g. during disk creation.

39ee704e75 libblock: Add read-ahead task 
Read-ahead requests were previously executed in the context of the
reading task.  This blocks the reading task until the complete read
with read-ahead transfer is finished.  A read-ahead task is introduced
to off-load the read-ahead transfer.  This allows the reading task to
work with the requested block more quickly.  The read-ahead is triggered
after two misses of ascending consecutive blocks or a read hit of a
block read by the most-recent read-ahead transfer.  The read-ahead
feature is configurable and can be disabled.

9b4422a251 Remove All CVS Id Strings Possible Using a Script 
Script does what is expected and tries to do it as
smartly as possible.

+ remove occurrences of two blank comment lines
  next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
  contain CVS Ids
+ If the processing left a blank line at the top of
  a file, it was removed.

b467782b53 libblock: Add rtems_bdbuf_set_block_size() 
The new function rtems_bdbuf_set_block_size() must be used to set the
block size of a disk device.  It will check if the block size is valid
and set the new fields block_to_media_block_shift and bds_per_group of
the rtems_disk_device structure.  This helps to avoid complex arithmetic
operations in the block device buffer get and read path.

796967c3df libblock: Change bdbuf API 
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.
