Extend the loader to parse the root file system mount options in /etc/fstab,
and set a new loader variable vfs.root.mountfrom.options with these options.
The root mount options must be a comma-delimited string, as specified in
/etc/fstab.
Only set the vfs.root.mountfrom.options variable if it has not been
set in the environment.

====================
When mounting the root file system, pass the mount options
specified in vfs.root.mountfrom.options, but filter out "rw" and "noro",
since the initial mount of the root file system must be done as "ro".
While we are here, try to add a few hints to the mountroot prompt
to give users and idea what might of gone wrong during mounting
of the root file system.

This avoids using non-standard behaviour of the old (upto FreeBSD 7) TTY
layer: it reprocesses the input queue when switching to canonical mode. The
new TTY layer does not provide this functionality and so read -t worked
very poorly (first character is not echoed, cannot be backspaced but is
still read).
This also agrees with what most other shells with read -t do.

Because we only support a single argument to tf_param, use 16 bits for
the pitch and 16 bits for the duration. While there, make the argument
unsigned. There isn't a single param call that needs a signed integer.

and calls to vn_vptocnp() by moving more of the common code to
vn_vptocnp(). Rename vn_vptocnp() to vn_vptocnp_locked() to signify that
cache is locked around the call.
Do not track buffer position by both the pointer and offset, use only
buflen to record the start of the free space.
Export vn_vptocnp() for external consumers as a wrapper around
vn_vptocnp_locked() that locks the cache and handles hold counts.

v_data is not-null before calling NULLVPTOLOWERVP(), and dropping the
interlock allows for reclaim to clean v_data and free the memory.
While there, remove unneeded semicolons and convert the infinite loops
to panics. I have a will to remove null_checkvp() altogether, or leave
it as a trivial stub, but not now.

This should not really matter for correctness, since vp->v_lock is
not locked before the call, and null_lock() holds the interlock,
but makes the control flow for reclaim more clear.

assigning ifnets from one vnet to another. Deletion of vnets is not
yet supported.
The interface is implemented as an ioctl extension so that no syscalls
had to be introduced. This should be acceptable given that the new
interface will be used for a short / interim period only, until the
new jail management framwork gains the capability of managing vnets.
This method for managing vimages / vnets has been in use for the past
7 years without any observable issues.
The userland tool to be used in conjunction with the interim API can be
found in p4: //depot/projects/vimage-commit2/src/usr.sbin/vimage/... and
will most probably never get commited to svn.
While here, bump copyright notices in kern_vimage.c and vimage.h to
cover work done in year 2009.

While there remain some incomplete aspects of the implementation (such
as incomplete auditing of some system calls), the implementation has

This attempts to fix the IPI handling code to correctly differentiate
between bitmapped IPIs and function IPIs. The Xen IPIs were on low numbers
which clashed with the bitmapped IPIs.
This commit bumps those IPI numbers up to 240 and above (just like in the i386
code) and fiddles with the ipi_vectors[] logic to call the correct function.
This still isn't "right". Specifically, the IPI code may work fine for TLB
shootdown events but the rendezvous/lazypmap IPIs are thrown by calling ipi_*()
routines which don't set the call_func stuff (function id, addr1, addr2) that
the TLB shootdown events are. So the Xen SMP support is still broken.

The code path this was copied from (sys/i386/i386/mp_machdep.c:ipi_selected())
handles bitmap'ed IPIs and normal IPIs via separate notification paths. Xen
SMP handles them the same way.
