- clean up USB detach logic. There seems to be some problems detaching multiple
USB HUBs connected in series from the root.
- after this patch the rule is:
1) Always use device_detach() on the USB HUB first.
2) Never just device_delete_child() on the USB HUB, because that function
will traverse to all the device leaves and free them first, and then the USB
stack will free the devices twice which doesn't work very well.
- make sure the did DMA delay gets set after the timeout has elapsed to make
logic more clear. There is no functional difference.

Right now if applications want to use the mouse on the command line,
they use sysmouse(4) and install a signal handler in the kernel to
deliver signals when mouse events arrive. This conflicts with my plan to
change to TERM=xterm, so implement proper VT200-style mouse input.
Because mouse input is now streamed through the TTY, it means you can
now SSH to another system on the console and use the mouse there as
well. The disadvantage of the VT200 mouse protocol, is that it doesn't
seem to generate events when moving the cursor. Only when pressing and
releasing mouse buttons.
There are different protocols as well, but this one seems to be most
commonly supported.

It is quite inconvenient that if an application for xterm uses 256 color
mode, text suddenly starts to blink (because of ;5; in the middle).
We'd better just implement 256 color mode and add a conversion routine
from 256 to 8 color mode, which doesn't seem to be too bad in practice.
Remapping colors is done quite simple. If one of the channels is most
actively represented, primary colors are used. If two channels are most
actively represented, secondary colors are used. If all three channels
are equal (gray), it picks between black and white.

devices that we also support, just not by default (thus only LINT or
module builds by default).
While currently there is only "/dev/full" [2], we are planning to see more
in the future. We may decide to change the module/dependency logic in the
future should the list grow too long.
This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

- Clear all registers before calling real mode interrupt handlers as we did
for dpms and vesa and re-enable the function as it should be fixed by this.
- Tidy up register access. For example, when we call INT 0x15, AH=0xc0,
we used to initialize AX=0xc000 to clear AL at the same time but it is
very confusing. We don't have to do this any more because we are explicitly
clearing all registers now.
- Check size of system configuration table although it is almost always 8.
This is to make sure we are not reading some random low physical memory.
Hopefully it is just zero in that case. :-)
- Fix some style nits and add more comments.

Also align setup descriptor on 32 bytes boundary. Tx buffer have no
alignment limitation so create dmamap without alignment
restriction[1]. Rx buffer still seems to require 4 bytes alignment
limitation but we can simply use MCLBYTES for size to map the
buffer instead of TULIP_DATA_PER_DESC as the buffer is allocated
with m_getcl(9).
de(4) supports up to TULIP_MAX_TXSEG segments for Tx buffers,
increase maximum dma segment size to TULIP_MAX_TXSEG * MCLBYTES.
While I'm here remove TULIP_DATA_PER_DESC as it is not used anymore.
This should fix de(4) breakage introduced after r176206.

o introduce PCIE_REGMAX and use it instead of ad-hoc constant
o where 'reg' parameter/variable is not already unsigned, cast it to
unsigned before comparison with maximum value to cut off negative
values
o use PCI_SLOTMAX in several places where 31 or 32 were explicitly used
o drop redundant check of 'bytes' in i386 pciereg_cfgread() - valid

I think a recent change to ACPI-CA is causing the interpreter to
