staging: add Lustre file system client support

Lustre is the most deployed distributed file system
in the HPC (High Performance Computing) world. The patch
adds its client side support.

The code is not very clean and needs to live in drivers/staging
for some time for continuing cleanup work. See
drivers/staging/lustre/TODO for details.

The code is based on Lustre master commit faefbfc04

http://review.whamcloud.com/#change,4778
http://review.whamcloud.com/#change,4779
http://review.whamcloud.com/#change,4780



All starting/trailing whitespaces are removed, to match kernel
coding style. Also ran scripts/cleanfile on all lustre source files.

[maked the Kconfig depend on BROKEN as the recent procfs changes causes
this to fail - gregkh]

		* Possible remaining coding style fix.
		* Remove deadcode.
		* Seperate client/server functionality. Functions only used by server can be
		removed from client.
		* Clean up libcfs layer. Ideally we can remove include/linux/libcfs entirely.
		* Clean up CLIO layer. Lustre client readahead/writeback control needs to better
		suit kernel providings.
		* Add documents in Documentation.
		* Other minor misc cleanups...
