kernel - Fix serious issue w/ smp_invltlb(), plus other issues.
* smp_invltlb() was running asynchronously when it really needs to run
synchronously. Generally speaking the asynchronous ipi did in fact work
pretty well but it still presents a 1uS window of opportunity which
bypasses normal write ordering safeties.
Run smp_invltlb() synchronously.
* Fixing the above lea to the discovery of an ACPI issue. The ACPI
cpu idle halt code, at least on the gigabyte phenom x 6 I've been
testing with, can cause IPIs to be lost. Not just delayed, straight
out lost. Gone. Poof. It doesn't matter whether the IPI is a
broadcast IPI or a directed IPI, it can still get lost.
This was particularly noticeable when I fixed smp_invltlb() and my
test box started locking up due to a random cpu sometimes not receiving
the Xinvltlb IPI, and it is quite possible that this issue was also
responsible for the random seg-faults we would sometimes get on 64-bit
boxes.
For now the acpi halt code has been disabled. It can be enabled with
sysctl machdep.cpu_idle_hlt=2 if you want to risk it.
* Use doreti_syscall_ret and doreti_iret in several cases that were
previously popping the interrupt frame and iret'ing manually. This
is operationally equivalent.
* Add a missing "sti" in the idle loop. Usually the cpu_idle_hook()
deals with this but there are some alternative paths which might not,
potentially causing interrupts to be delayed unnecessarily.
At worst the idle thread has an extra sti in it.
* Add v_smpinvltlb to struct vmmeter, plus some reserved slots for
future expansion.
* Adjust vmstat -s to report smpinvltlb's.

nrelease: Fix an annoying bug that was preventing the ISOs from booting UP.
It seems our CD9660 support in libstand at least has some problems with
directory names containing dots. This prevented the LiveCD to properly
boot the UP kernel. Don't ask me about how it ended up using the SMP
kernel in this case, but that's what it did, making the UP boot
impossible. My guess is it has something to do with the order in which
stuff had been added to the ISO. But that's pure speculation. I'm not
even sure about the dot part. It might as well be directory name length.
In any case, UP boot from the LiveCD was broken.
To fix all this, install the UP kernel to /boot/UP and the SMP kernel to
/boot/SMP on the LiveCD and images. They will be picked up by the
installer from there by a separate commit.
While here, remove some non-functional code from dloader.menu. We can't

kernel - Fix another hard critical section issue with syscons, revamp locking
* Use the new mtx_spinlock() facility instead of spinlock(). The new
facility supports reetrant locks.
* Call all sc_*() functions with the syscons lock held.
* Fix an issue in blink_screen() where a hard critical section panic
could potentially occur.
* Fix an issue in sc_puts() where adjusting the keyboard LED could still
cause a hard critical section panic. We just let the keyboard LED state
be wrong for now.

kernel - revamp mtx_spinlock()
* Revamp mtx_spinlock(), add mtx_spinlock_try(), and add mtx_spinunlock().
* Enter a proper hard critical section when using mtx_spinlock*(),
just like the normal spinlock() code does.
The difference is that mtx spinlocks have a ref count and thus are
reentrant.
* mtx_spinlock*() is not used in the code yet. A followup commit will
begin using it for the syscons lock.

kernel - Force NFSv3 for diskless nfs mount
* Ignore any file handles passed from bootp. These are NFSv2 handles
and NFSv2 just doesn't have the directory support needed if the
server is running a filesystem with 64-bit directory cookies (as HAMMER
does).
This will force the kernel's diskless nfs mount to re-authorize and
acquire a NFSv3 handle for the root mount.
* Undo a bit of a previous commit where I tried to enable readdirplus for
NFSv2 to workaround NFSv2 directory cookie issues. It just doesn't work.
readdirplus is again force-disabled for NFSv2 mounts.

HAMMER VFS - Minor bug (caught by assertion panic)
* A snapshot can sometimes contain visible inodes whos nlinks count is 0,
essentially the snapshot 'catches' the file in the middle of being deleted.
* HAMMER was attempting to truncate the data for such inodes if the file
were opened and then closed, and failed to check whether the inode was a
snapshot or a current inode. This flowed through until it hit an assertion
designed to detect precisely that case.
* Fixed by adding a check to determine if the inode is a snapshot and/or
the filesystem is mounted read-only.

kernel - Fix NFS client & server bugs
* A very long standing bug in the server cache was finally whacked. The
write-gather code was improperly returning the wrong mbuf for the server
to reply with, causing client stalls. This behavior depends on the client
doing burst asynchronous writes. Newer releases of DragonFly do burst
asynchronous writes but older ones tended not to.
* The server cache was not MPSAFE. Add a MP token to fix that.
* Remove critical sectons from the server cache which are no longer needed.
* Fix a potential client-side rpc request race where a request's
NEEDSXMIT flag is not set until after the request possibly blocks,
which can lead to issues if another thread picks up the request
and then believes that it has already been transmitted when it
has not.
* Document a big problem with NFSv2 and HAMMER-served directories. NFSv2
only has 32-bit directory cookies. It is possible to work around the
problem by using rdirplus (which is the default now). However, some
servers may not be able to handle rdirplus with a NFSv2 mount.
Users who need to serve out NFSv2 cannot serve HAMMER directories
with NFSv2 unless the clients support rdirplus.
Our defaults are NFSv3 and rdirplus and NFSv3 does NOT have this problem.
