5807 - incorrect outstanding SEND accounting
    changed refcounting inlines to macros to improve logging
    cleanup unused per-work-item debug on send

*   lctl debug_file wasn't passing the mode argument to open(O_CREAT)
    fixed with restrictive (owner only) permissions

*   5803 ranal initialisation fix

r=adilger

First stab at improving some user visible error messages.

	  - removed CFS_DECL_SPIN*
	    just use 'spinlock_t' and initialise with spin_lock_init()

	  - removed CFS_DECL_MUTEX*
	    just use 'struct semaphore' and initialise with init_mutex()

	  - removed CFS_DECL_RWSEM*
	    just use 'struct rw_semaphore' and initialise with init_rwsem()

	  - renamed cfs_sleep_chan -> cfs_waitq
	            cfs_sleep_link -> cfs_waitlink

          - fixed race in linux version of arch-independent socknal
  	    (the ENOMEM/EAGAIN decision).

	  - Didn't fix problems in Darwin version of arch-independent socknal
 	    (resetting socket callbacks, eager ack hack, ENOMEM/EAGAIN decision)

	  - removed libcfs types from non-socknal header files (only some types
	    in the header files had been changed; the .c files hadn't been
	    updated at all).

	  - Updated lustre b1_4 to match

fix debug_daemon size problem

a typo fix(forget goto) for debug_daemon utils

temp fix debug_daemon bug on HEAD

*   Removed S_???NAL in favour of a single S_NAL

*   NB liblustre needs attention

- don't generate a temp filename for a raw dump
- don't unlink non-regular files (e.g. /dev/null)
- don't report an error if kernel doesn't dump anything (fix mismerge?)

- added ldiskfs module info generation to portals/utils/debug.c
- added packing/unpacking for mea in lmv_obd.c
- small cleanups.

1)some fix in fsfilt_snap_ext3 and fsfilt_snap_smfs.
2)add smfs_cow.c in smfs.
3)remove snapfs in Makefile.in and configure.in

I haven't re-tested the AMD functionality since landing, but I did
test iozone and dbench to ensure sanity.

b_cmobd_merge should not be used for any further development or testing!

cMD_PRE_CMD_SMASH are the relevant tags.

The pre-smashing contents of HEAD will be committed by yury into b_cmd as a
merge of the two branches.  These will be stabilized on b_cmd and eventually
landed onto HEAD.

 b 2074 comment 33 -- cleanup code using fstat()

r=adilger
(didn't see regressions in buffalo, confirmed read throughput increases
with sf and fpp multi-node IOR)

This cleans up llite's readpage path and implements our own read-ahead window
that hangs off of ll_file_data.  The broad goal is to keep a fair amount of
read-ahead pages issued and queued which can be fired off into read rpcs as
read-ahead rpcs are completed.

 - dozens and dozens of fixes for working with 2.6 kernels
 - new 2.4 kernel APIs
 - uncountable bug fixes

- remove extN/ files
