- Always program RX configuration register from scratch instead of
doing read/modify/write.
- Rename re_setmulti() to re_set_rxmode() to be reflect reality.
- Simplify hash filter logic a little while I am here.

Even though VT100-like devices can display non-ASCII characters, they do
not use an 8-bit character set. Special escape sequences allow the VT100
to switch character maps. The special graphics character set stores the
box drawing characters, starting at 0x60, ending at 0x7e. This means
we now pass the character map tests in vttest, even the save/restore
cursor test, combined with character maps. dialog(1) also works a lot
better now.
This commit also includes some other minor fixes:
- Default to 24 lines in teken_demo when using xterm emulation.
- Make white foreground and background work in teken_demo.
Cons25 doesn't seem to use a straight 1:1 mapping to the ANSI colors,
but uses the same color numbers as at least used by syscons on i386. I
suspect if you change the definitions on a different architecture,
things may break? Not sure.
Add a small array to convert syscons-style color codes to ANSI
equivalents, which are used by libteken internally. I didn't notice this
bug, because I only tested my code with black, white and green, all of
them shared the same numbers.
It turns out I forgot to implement two escape sequences that allows the
user to change the default foreground and background colors. I thought
they were implemented by syscons itself, but vidcontrol just generates
some escape sequences, which get interpreted by the terminal emulator.

The teken library already supports UTF-8 handling and xterm emulation,
but we have reasons to disable this right now. Because we should make it
easy and interesting for people to experiment with these features, allow
them to be set in kernel configuration files.
Before this commit we had a flag called `TEKEN_CONS25' to enable
cons25-style emulation. I'm calling it the opposite now, `TEKEN_XTERM',
because we want to enable it in kernel configuration files explicitly.

by writing all 1's to it to determine its length. This fixes issues with
MCFG on at least some machines where a trashed BAR claimed subsequent
attempts at PCI config transactions because the addresses in the MCFG
window fell in the decoding range of the BAR.
In general it is a bad idea to leave the BARs enabled while we are
frobbing with them in this manner.

The digi(4) driver directory contains some files that cannot be checked
out on Windows filesystems. This isn't a big deal, but the files aren't
used anyway.
There are still some other places where checkouts on Windows don't work,
such as VFS_MOUNT.9/vfs_mount.9. This should already be a small
improvement.

work when the bus attaches its own children. Instead of hardcoding a unit
number and returning BUS_PROBE_NOWILDCARD, which will break multiple iicbus
systems, check in the probe routine whether the device address is 0. Real
I2C devices will never have this address, but devices added with
BUS_ADD_CHILD() will.

for jumbo frame.
o Nuke unneeded jlist lock which was used to protect jumbo buffer
management in local allocator.
o Added a new tunable hw.mskc.jumbo_disable to disable jumbo
frame support for the driver. The tunable could be set for
systems that do not need to use jumbo frames and it would
save (9K * number of Rx descriptors) bytes kernel memory.
o Jumbo buffer allocation failure is no longer critical error
for the operation of msk(4). If msk(4) encounter the allocation
failure it just disables jumbo frame support and continues to
work without your intervention.
Using local allocator had several drawbacks such as requirement of
large amount of continuous kernel memory and fixed (small) number
of available buffers. The need for large continuous memory resulted
in failure of loading driver with kldload on running systems.
Also small number of buffer used in local allocator showed poor
performance for some applications.
Add missing set frame data pointer call. The
function call was missed when zero copy was
introduced in UMASS.

Remove dependancy towards the USB config thread in
the USB serial core. Use USB process msignalling
instead. Saves a little memory and hopefully makes
the code more understandable.

Remove "vbus_interrupt" method from bus methods and use
a global function instead for the various drivers using it.
The reason for the removal is to simplify the code.

Reduce the number of callback processes to 4 per
USB controller. There are two rough categories:
1) Giant locked USB transfers.
2) Non-Giant locked USB transfers.
On a real system with many USB devices plugged in the
number of processes reported by "ps auxw | grep USBPROC"
was reduced from 40 to 18.

This change is about removing three fields from "struct usb2_xfer"
which can be reached from "struct usb2_xfer_root" instead and cleaning
up the code after this change. The fields are "xfer->udev",
"xfer->xfer_mtx" and "xfer->usb2_sc". In this process the following
changes were also made:
Rename "usb2_root" to "xroot" which is short for "xfer root".
Rename "priv_mtx" to "xfer_mtx" in USB core.
The USB_XFER_LOCK and USB_XFER_UNLOCK macros should only be used in
the USB core due to dependency towards "xroot". Substitute macros
for the real lock in two USB device drivers.

Factor out roothub process into the USB bus structure for
all USB controller drivers. Essentially I am trying to
save some processes on the root HUB and get away
from the config thread pradigm. There will be a follow up
commit where the root HUB control and interrupt callback
will be moved over to run from the roothub process.
Total win: 3 processes become 1 for every USB controller.
