pooka 61e8303e9d Remove the "struct lwp *" argument from all VFS and VOP interfaces. 
The general trend is to remove it from all kernel interfaces and
this is a start.  In case the calling lwp is desired, curlwp should
be used.

quick consensus on tech-kern

ad 7dad9f7391 Merge from vmlocking: 
- Split vnode::v_flag into three fields, depending on field locking.
- simple_lock -> kmutex in a few places.
- Fix some simple locking problems.

pooka f5ba107ccd Introduce WILLMAKE for vnode operations which create a new vnode. 
Insert a KASSERT along the return path of such operations to check
that the operation set the vnode size.

pooka d89a0720df Generate preprocessor macros for vop offsets in vfs op descs. And 
use these symbols in the desc structures instead of magic numbers.
No functional change, except VOP_FOO_DESCOFFSET macros in vnode_if.h.

(It is nice if all files that should not be edited have DO NOT EDIT in them.)

thorpej 11afd11faa Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*() 
calls to ensure that the vnode lock state is as expected when the VOP
call is made.  Modify vnode_if.src to set the expected state according
to the documenting lock table for each VOP.  Modify vnode_if.sh to emit
the checks.

Notes:
- The checks are only performed if the vnode has the VLOCKSWORK bit
  set.  Some file systems (e.g. specfs) don't even bother with vnode
  locks, so of course the checks will fail.
- We can't actually run with VNODE_LOCKDEBUG because there are so many
  vnode locking problems, not the least of which is the "use SHARED for
  VOP_READ()" issue, which screws things up for the entire call chain.

Inspired by similar changes in OpenBSD, but implemented differently.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

martin c9803fbf98 Remove over-const-ification. 
This structures are actually modified at kernel init time by vfs_op_init.

XXX - looks like the state after initialization is pretty const and with
some magic in the generator script (and appropriate changes to vfs_op_init)
it could be made const.

thorpej 7f3e4b0331 If building an LKM, always cause it to use the non-inline version 
of the vnode ops, and if LKM support is included in the kernel,
always include the non-inline stubs regardless of whether or not
they're being used in the static kernel iamge.

thorpej 9d482308b1 Allow the VOP_*() calls to be un-inlined with the VNODE_OP_NOINLINE 
kernel option.  Saves 36k of kernel text on an i386 GENERIC.  Useful
for install media kernels, small memory systems, embedded systems.
