kernel: Remove numerous #include <sys/thread2.h>.

Most of them were added when we converted spl*() calls to
crit_enter()/crit_exit(), almost 14 years ago. We can now
remove a good chunk of them again for where crit_*() are
no longer used.

I had to adjust some files that were relying on thread2.h
or headers that it includes coming in via other headers
that it was removed from.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

Convert the global 'bioops' into per-mount bio_ops. For now we also have
to have a per buffer b_ops as well since the controlling filesystem cannot
be located from information in struct buf (b_vp could be the backing store
so that can't be used). This change allows HAMMER to use bio_ops.

Change the ordering of the bio_ops.io_deallocate call so it occurs before
the buffer's B_LOCKED is checked. This allows the deallocate call to set
B_LOCKED to retain the buffer in situations where the target filesystem
is unable to immediately disassociate the buffer. Also keep VMIO intact
for B_LOCKED buffers (in addition to B_DELWRI buffers).

HAMMER will use this feature to keep buffers passively associated with
other filesystem structures and thus be able to avoid constantly brelse()ing
and getblk()ing them.

Implement (non-bootable) GPT support. If a PMBR partition type is detected
the rest of the MBR is ignored and the GPT partition table will be parsed
into slices. GPT partition 0 will be s0, GPT partition 1 will be s1, etc.
Bootable support is forthcoming.

Remove support for COMPATIBILITY_SLICE when a MBR/GPT table is present. That
is, the COMPATIBILITY_SLICE (s0) will still point to the dangerously
dedicated disklabel or be synthesized for a CD, but it will no longer point
to the 'first BSD slice' in a real MBR or GPT table. For GPT tables
slice 0 (s0) will point at GPT partition #0, slice 1 (s1) at
GPT partition #1, etc.

Redo the reserved sector handling code. There is now a single reserved
sector count instead of separate fields for the slice layer and disklabel
layer.

Redo the disklabel snooping code. Note that you cannot run an old
/sbin/disklabel in raw (-r) mode with a new OS because the old disklabel
will not turn on snooping. For now the on-disk format remains the same,
but more changes may be forthcoming (after discussion). I would like to
get rid of the snooping entirely.

Add kuuid_is_nil() and use it to ignore unset GPT paritions.

Introduce DSO_COMPATMBR. This forces an MBR sector to be reserved in front
of a disklabel even when the target disk does not have slices. It is used
by the CCD and VN devices to keep the disklabel aligned the same way it has
been historically.

the CCD use that filesystem type for safety.

* The VN device now uses 64 bit sector numbers and can handle block devices
up to what is supported by the filesystem (typically 8TB). This change
was made primarily so we can test future disklabel / partition table
support.

* Pass 64 bit LBAs to various block devices and to the SCSI layer.

Continue untangling the disklabel. Reorganize struct partinfo and the
DIOCGPART ioctl to extract the required information directly, and fix
the DIOCGPART ioctl direction so userland can use it.

This removes numerous disklabel references, particularly from the filesystem
code which was doing silly indirections just to figure out the sector size.

NOTE: The absolute byte offset of the slice or partition (relative to the
base of the raw disk) is also made available, but is not currently used
by the kernel.

Use SYSREF to reference count struct vnode. v_usecount is now

Use SYSREF to reference count struct vnode. v_usecount is now
v_sysref(.refcnt). v_holdcnt is now v_auxrefs. SYSREF's termination state
(using a negative reference count from -0x40000000+) now places the vnode in
a VCACHED or VFREE state and deactivates it. The vnode is now assigned a
64 bit unique id via SYSREF.

vhold() (which manipulates v_auxrefs) no longer reactivates a vnode and
is explicitly used only to track references from auxillary structures
and references to prevent premature destruction of the vnode. vdrop()
will now only move a vnode from VCACHED to VFREE on the 1->0 transition
of v_auxrefs if the vnode is in a termination state.

vref() will now panic if used on a vnode in a termination state. vget()
must now be used to explicitly reactivate a vnode. These requirements
existed before but are now explicitly asserted.

vlrureclaim() and allocvnode() should now interact a bit better. In
particular, vlrureclaim() will do a better job of finding vnodes to flush
and transition from VCACHED to VFREE, and allocvnode() will do a better
job finding vnodes to reuse without getting blocked by a flush.

allocvnode now uses a real VX lock to sequence vnodes into VRECLAIMED. All
vnode special state processing now uses a VX lock.

Vnodes are now able to be slowly returned to the memory pool when
kern.maxvnodes is reduced at run time.

Various initialization elements have been moved to CTOR/DTOR and are
no longer in the critical path, improving performance. However, since
SYSREF uses atomic_cmpset_int() (aka cmpxchgl), which reduces performance
somewhat, overall performance tends to be about the same.
