Add Lustre filesystem to getconf/pathconf/statvfs

Due to the way getconf is implemented, it needs to explicitly list each filesystem type in order to determine the correct FILESIZEBITS and
LINK_MAX values to use for each filesystem.

Attached is a patch against glibc-2.14-9-g29f6547, though it also
patches at least as far back as glibc-2.12.



Add Lustre filesystem to getconf/pathconf/statvfs

Add definitions of LUSTRE_SUPER_MAGIC and LUSTRE_LINK_MAX, and add
detection into __statfs_filesize_max(), __statvfs_getflags(), and
__statfs_link_max() so that getconf(), pathconf(), statvfs(), etc.
can detect this filesystem type correctly.

The LUSTRE_SUPER_MAGIC type is already handled by coreutils, but
it seems that coreutils and glibc do not share the magic values.

I've applied the patch with a tiny change.

Next time update the copyright year in the files and pay attention to the file encoding.

Should have been closed already.
