Update ng_tty for MPSAFE TTY.
This changes from a line discipline to the tty_hooks mechanism. Data will come
in directly via rint_bypass and sent to the peer node in a single mbuf.
As line disciplines are no longer used a new netgraph command called
NGM_TTY_SET_TTY is used to attach the tty. This takes a pointer to to the open
file descriptor of the tty and registers the tty hooks. When the tty disappears
the node will shutdown.

Step 1.5 of importing the network stack virtualization infrastructure
from the vimage project, as per plan established at devsummit 08/08:
http://wiki.freebsd.org/Image/Notes200808DevSummit
Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.
Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().
Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).
All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

Wait until after dropping the receive socket buffer lock to allocate space

This reduces contention on the lock and CPU system time in certain UDP

Remove function prototypes of nonexistent TTY functions.
It turns out I overlooked some function prototypes that were actually
TTY related, but were stored in <sys/conf.h> to implement the D_TTY

- Make gvinum header on-disk structure consistent on all platforms by storing
the gvinum header in fields of fixed size and in a big endian byte order
rather than the size and byte order of the actual platform.
Note that the change is backwards compatible with the old gvinum configuration
format, but will save the configuration in the new format when the 'saveconfig'
command is executed.

Various cleanups for soreceive_dgram():
- Update or remove comments that were left over from the original
soreceive_generic() implementation. Quite a few were misleading in the
context of the new code.
- Since soreceive_dgram() has a simpler structure, replace several gotos
with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
the loop invariant (since m is always NULL, don't check for and handle
non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
sbwait() returns, which may help reduce lock contention (etc).
- Assume PR_ATOMIC since we assert it at the top of the function.

Improve the `pkill -t' handling, which I changed in my previous commit.
In my previous commit I disabled pkill(1)'s automatic prepending of the

both possible device names when called.
Do not mangle if_oerrors of the underlying interface. This counter
belongs solely to the driver.
We don't lose any statistics with this change, because in a error

Improve support for multiple block read/write. This code is currently
disabled by default because there's problems with it on AT91RM9200,
currently the only host controller in the tree. I've not had time to
track those problems to ground. I'm committing because this is
important for other host controllers that are in the pipeline.
vm_fault_hold_user_pages will not return if an address in the range passed in is mapped RO
but an RW mapping exists for the underlying page. This change fixes the bug by using the
page / NULL returned from pmap_extract_and_hold to determine whether or not vm_fault needs
to be called.
Move the code for doing out-of-memory grass from vm_pageout_scan()

Distinguish between cmd/parameters used for clone operations and
all others. Use this to disambiguate cmd line arguments that can
be either clone params or regular parameters so, in particular,
"bssid" again works as a regular parameter.
While here leverage the above to improve the logic for flushing
clone operations on the first !clone cmd line parameter.
Since in some cases (when found obsolete) 'make' can be builded earlier

Return G_PART_PROBE_PRI_HIGH instead of G_PART_PROBE_PRI_NORM
if the probe succeeds. This guarantees that the BSD scheme
wins over the MBR scheme when MBR gets to probe first. Build-
or link-time conditions can cause schemes to end up in the
linker set in a different order. Normally BSD is before MBR
in the linker set and as such get to probe first. But typically
when the kernel gets rebuild or relinked, this can change.
Insert the null scheme at the head. This does not change any
functionality, but creates an invariant: the first element
on the list is always the null scheme.
The parameters to the MMCBR_ACQUIRE_HOST and MMCBR_RELEAES_HOST were

Several documentation fixups related to device minor/major numbers:
- Document the minor(3), major(3) and makedev(3) macro's. They also
apply to umajor() and uminor() in the kernel, but hopefully we'll sort
that out one day.
- Briefly dev2unit() inside the make_dev(9) manual page, since this is
now the preferred macro to obtain character device unit numbers inside
the kernel.
- Remove the device_ids(9) manual page. It contains highly inaccurate
information, such as a description of the nonexistent major().

age, or OpenBSD origins for thse). Note the current values that are

More cleanup could be done here: NBPG appears to be spelled PAGE_SIZE

think. These constants duplicate the MI constants and are sprinkled
into the mips code only. Further investigation is needed.

Don't automatically prepend the "tty" prefix to `pkill -t' arguments.
Because we now enforce UNIX98-style PTY's, we now use a lot of TTY's
that don't have the traditional /dev/ttyXX naming scheme. pkill(1)'s -t
flag automatically prepended the word "tty" to each TTY that was passed
on the command line. This meant that `pkill -t pts/0' was actually
converted to /dev/ttypts/0. Disable this broken behaviour for now.
