Added __acquires / __releases sparse locking annotations
to lock_res_and_lock() and unlock_res_and_lock() functions
in l_lock.c, to fix below sparse warnings:
l_lock.c:47:22: warning: context imbalance in 'lock_res_and_lock' - wrong count at exit
l_lock.c:61:6: warning: context imbalance in 'unlock_res_and_lock' - unexpected unlock

Since SUN is no longer around and there's no point in contacting them,
just remove that whole thing. Copy of GPL is available online anyway
(URLs to be updated in next patch).

Convert most of the ldlm lock's l_flags references from direct
bit twiddling to using bit specific macros. A few multi-bit
operations are left as an exercise for the reader.
The changes are mostly in ldlm, but also in llite, osc and quota.
Also add a multi-bit (mask) test.

Since the code we have is Lustre-client only, this function
always returns 0, so drop it and amend all the callsites to
drop dead code.
One of the places also sets LDLM_FL_NS_SRV to indicate a lock
is in a server namespace. This too cannot happen in this code,
so drop all such checks as well.

We need to remove the ccflags from the Lustre code as it prevents
individual object files from building properly in the kernel build
system. It also hids the horrid mess that the Lustre include files are
made up of.
Start out by removing the toplevel ccflags variable pointing to
drivers/staging/lustre/include/ as a valid include path. This requires
the absolute include markings of a bunch of .h and .c files, which is
also done here.

* lustre/include/lustre_dlm.h: Remove all bit fields and the unused
weighing callback procedure. respell LDLM_AST_DISCARD_DATA as
LDLM_FL_AST_DISCARD_DATA to match other flags.
* .gitignore: ignore emacs temporary files
* autogen.sh: rebuild the lock bits, if autogen is available.
* contrib/bit-masks/lustre_dlm_flags.def: define the ldlm_lock flags
* contrib/bit-masks/lustre_dlm_flags.tpl: template for emitting text
* contrib/bit-masks/Makefile: construct the .c and .h files
The .c file is for constructing a crash extension and is not
preserved.
* contrib/bit-masks/.gitignore: ignore built products
* lustre/contrib/wireshark/packet-lustre.c: use built files instead
of local versions of the defines.
In the rest of the modified sources, replace flag field references
with bit mask references.
* lustre/osc/osc_lock.c: removed osc_lock_weigh, too

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
commit faefbfc0460bc00f2ee4c1c1c86aa1e39b9eea49

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