Add a local context structure to the SMP lock API for acquire and
release pairs. This context can be used to store the ISR level and
profiling information. It may be later used to enable more
sophisticated lock algorithms, e.g. MCS locks.
There is only one lock that cannot be used with a local context. This
is the per-CPU lock since here we would have to transfer the local
context through a context switch which is very complicated.
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.
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.

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.
