Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Make VOP_RECLAIM do the last unlock of the vnode.

VOP_RECLAIM naturally has exclusive access to the vnode, so having it
locked on entry is not strictly necessary -- but it means if there
are any final operations that must be done on the vnode, such as
ffs_update, requiring exclusive access to it, we can now kassert that
the vnode is locked in those operations.

We can't just have the caller release the last lock because some file
systems don't use genfs_lock, and require the vnode to remain valid
for VOP_UNLOCK to work, notably unionfs.

Add VOP_FALLOCATE and VOP_FDISCARD to every vnode ops table I can
find.

The filesystem ones all call genfs_eopnotsupp - right now I am only
implementing the plumbing and we can implement fallocate and/or
fdiscard for files later.

The device ones call spec_fallocate (which is also genfs_eopnotsupp)
and spec_fdiscard, which dispatches to the device-level op.

The fifo ones all call vn_fifo_bypass, which also ends up being
EOPNOTSUPP.

C99 section 6.7.2.3 (Tags) Note 3 states that:

  A type specifier of the form

	enum identifier

  without an enumerator list shall only appear after the type it
  specifies is complete.

which means that we cannot pass an "enum vtype" argument to
kauth_access_action() without fully specifying the type first.
Unfortunately there is a complicated include file loop which
makes that difficult, so convert this minimal function into a
macro (and capitalize it).

  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

The VATTR_NULL/VREF/VHOLD/HOLDRELE() macros lost their will to live
years ago when the kernel was modified to not alter ABI based on
DIAGNOSTIC, and now just call the respective function interfaces
(in lowercase).  Plenty of mix'n match upper/lowercase has creeped
into the tree since then.  Nuke the macros and convert all callsites
to lowercase.

be printed when it's used (obviously, only in DIAGNOSTIC kernels).

a smorgasbord of improvements to vnode locking and path lookup:
 - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP().
   these now always return the parent vnode locked.  namei() works as before.
   lookup() and various other paths no longer acquire vnode locks in the
   wrong order via vrele().  fixes PR 32535.
   as a nice side effect, path lookup is also up to 25% faster.
 - the above allows us to get rid of PDIRUNLOCK.
 - also get rid of WANTPARENT (just use LOCKPARENT and unlock it).
 - remove an assumption in layer_node_find() that all file systems implement
   a recursive VOP_LOCK() (unionfs doesn't).
 - require that all file systems supply vfs_vptofh and vfs_fhtovp routines.
   fill in eopnotsupp() for file systems that don't support being exported
   and remove the checks for NULL.  (layerfs calls these without checking.)
 - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just
   adjust which vnode is locked.  fixes PR 33374.
 - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

conditional calls/assignments method.  The code is clearer this way,
and benchmarks at about the same speed.

Update the mod and access times directly from ptyfs_read() and
ptyfs_write() rather than setting a flag and updating these times
through ptyfs_itimes() at some indeterminate time in the future.
However, just use the "time" variable to set the times instead of
using a potentially expensive call to nanotime().  A HZ resolution
on these timestamps is more than enough.

(Possibly incomplete) fix for PR kern/31430.
OK'd be christos@.
