d14e51c95c Add support for the Coda 6.x venus<->kernel interface. This extends
FIDs to be 128-bits wide and adds support for realms.

Add a new CODA_COMPAT_5 option, which requests support for the old
Coda 5.x interface instead of the new one.

Create a new coda5.ko module that supports the 5.x interface, and make
the existing coda.ko module use the new 6.x interface. These modules
cannot both be loaded at the same time.

Obtained from:	Jan Harkes & the coda-6.0.2 distribution,
		NetBSD (drochner) (CODA_COMPAT_5 option).

e6e370a7fe - Replace v_flag with v_iflag and v_vflag
- v_vflag is protected by the vnode lock and is used when synchronization
   with VOP calls is needed.
 - v_iflag is protected by interlock and is used for dealing with vnode
   management issues.  These flags include X/O LOCK, FREE, DOOMED, etc.
 - All accesses to v_iflag and v_vflag have either been locked or marked with
   mp_fixme's.
 - Many ASSERT_VOP_LOCKED calls have been added where the locking was not
   clear.
 - Many functions in vfs_subr.c were restructured to provide for stronger
   locking.

bd78cece5d Change the kernel's ucred API as follows:
- crhold() returns a reference to the ucred whose refcount it bumps.
- crcopy() now simply copies the credentials from one credential to
  another and has no return value.
- a new crshared() primitive is added which returns true if a ucred's
  refcount is > 1 and false (0) otherwise.

2395531439 Introduce a global lock for the vm subsystem (vm_mtx).
vm_mtx does not recurse and is required for most low level
vm operations.

faults can not be taken without holding Giant.

Memory subsystems can now call the base page allocators safely.

Almost all atomic ops were removed as they are covered under the
vm mutex.

Alpha and ia64 now need to catch up to i386's trap handlers.

FFS and NFS have been tested, other filesystems will need minor
changes (grabbing the vm lock when twiddling page properties).

fb919e4d5a Undo part of the tangle of having sys/lock.h and sys/mutex.h included in
other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

e8e04c2b37 Venus must be passed O_CREAT flag on VOP_OPEN iff this is
a creat so that we can will allow a mode 444 file to be
written into.  Sync with the latest coda.h and deal with
collateral damage.

6a6e8b2134 Put "stray" printouts under DIAGNOSTIC. Make everything build
with DEBUG on.  Add support for lkm.  (The macro's don't work
for me; for a good chuckle look at the end of coda_fbsd.c.)
