* fix for build problem when b1_4_sles10 is actually built on sles10

(shame on me for not using cvsdiffclient!)

description: After calling 'symlink(path, newpath)', of which path(link target)
doesn't exist,  the second symlink call still success, which should return
-EEXIST.

DESCRIPTION:
    When doing fcntl() file locking calls in a liblustre client via libsysio,
successful lock calls return random non-zero values due to use uninitialized
value as return value.

DESCRIPTION:
    keep CFS up to date with latest libsysio version

* the b1_5_* and b_iam* branches will to continue to use the old libsysio
* until they can be updated from b1_4 liblustre because of the API change.

- API changegetdirentries->filldirentries changed from upstream
- symlink following fixup
- fix getcwd for out-of-libsysio directory
- lseek fixups for large files
- flock/fcntl fixups for 64-bit systems

Use 64-bit variable for libsysio lseek64() internal return value.
Update liblustre sanity.c to use 64-bit IO functions where needed.

Description: liblustre could not open files whose last component is a symlink
Details    : sysio_path_walk() would incorrectly pass the open intent to
	     intermediate path components.

Build fix for HEAD.

libsysio fixes which always apply the umask before calling liblustre.
With these changes, liblustre can stop worrying about the umask entirely.

which makes debugging at least theoretically possible.
