Sebastian Huber 53da07e436 Filesystem: PR1255: Move offset update to handlers 
It is now the responsibility of the read() and write() handler to update
the offset field of the IO descriptor (rtems_libio_t).  This change
makes it possible to protect the IO descriptor from concurrent access by
per file locks.

Joel Sherrill 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.

Sebastian Huber 30d412469c Filesystem: PR1398: Fix lseek() mechanic 
According to POSIX the lseek() function shall not, by itself, extend the
size of a file.

Remove the size field of rtems_libio_t.  A file has only one size but
may have multiple open file descriptors.  Thus a file size field in the
file descriptor may lead to inconsistencies.

New default handlers rtems_filesystem_default_lseek_file() and
rtems_filesystem_default_lseek_directory().

Sebastian Huber ac50df2304 libblock: PR2040: Add starvation threshold

Sebastian Huber 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.

Sebastian Huber c08072ce31 PR2040: libblock: Avoid erased blocks starvation 
The compaction process needs erased blocks.  It is only possible to
erase an entire segment.  Thus in order to make a progress we always
need enough erased blocks to empty a used or available segment which can
be erased in turn.  A (possibly the worst case) lower bound of erased
blocks is the block count of the largest segment.  The number of
unavailable blocks specified by the configuration will be used to
determine the erase blocks starvation situation.  The number of
unavailable blocks must be greater than or equal to the number of blocks
in the largest segment.

Sebastian Huber 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.
