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.
o A new data structure rtems_filesystem_global_location_t was
introduced to be used for
o the mount point location in the mount table entry,
o the file system root location in the mount table entry,
o the root directory location in the user environment, and
o the current directory location in the user environment.
During the path evaluation global start locations are obtained to
ensure that the current file system instance will be not unmounted in
the meantime.
o The user environment uses now reference counting and is protected
from concurrent access.
o The path evaluation process was completely rewritten and simplified.
The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation
method. Recursive calls in the path evaluation have been replaced
with iteration to avoid stack overflows. Only the evaluation of
symbolic links is recursive. No dynamic memory allocations and
intermediate buffers are used in the high level path evaluation. No
global locks are held during the file system instance specific path
evaluation process.
o Recursive symbolic link evaluation is now limited by
RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value
via sysconf().
o The device file system (devFS) uses now no global variables and
allocation from the workspace. Node names are allocated from the
heap.
o The upper layer lseek() performs now some parameter checks.
o The upper layer ftruncate() performs now some parameter checks.
o unmask() is now restricted to the RWX flags and protected from
concurrent access.
o The fchmod_h and rmnod_h file system node handlers are now a file
system operation.
o The unlink_h operation has been removed. All nodes are now destroyed
with the rmnod_h operation.
o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system
operations.
o The path evaluation and file system operations are now protected by
per file system instance lock and unlock operations.
o Fix and test file descriptor duplicate in fcntl().
o New test fstests/fsnofs01.
* psxreaddir/psxreaddir.scn, psxreaddir/test.c: Do not test for
rewinddir(NULL) since we are now using newlib's implementation and it
does not check for NULL. This causes a fault on some targets.
* psxcancel/init.c: Include <rtems/console.h> instead of <console.h>.
* psxmount/test.c: Include <rtems/imfs.h> instead of <imfs.h>.
* psxreaddir/test.c: Include <rtems/imfs.h> instead of <imfs.h>.
* psxstat/test.c: Include <rtems/imfs.h> instead of <imfs.h>.
* Per PR47 add support for buffered test output. This involved
adding defines to redirect output to a buffer and dump it when
full, at "test pause", and at exit. To avoid problems when redefining
exit(), all tests were modified to call rtems_test_exit().
Some tests, notable psxtests, had to be modified to include
the standard test macro .h file (pmacros.h or tmacros.h) to
enable this support.

* psxmount/test.c, psxmount/psxmount.scn: Improve output to report
expected error condition in one case.
* psxreaddir/test.c, psxreaddir.scn: Added test cases to exercise
readdir() of root of mounted filesystem. Also corrected the screen
file for some mistakes noticed in this effort.
