Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

debugging levels to off by default. Now that debug levels can be
tweaked by sysctl we don't need to go through hoops to get the
different usb parts to produce debug data.
that the attach succeeded. (Fixes a potential panic for devices
that fail to attach properly and are subsquently unplugged and then
plugged back in again.)

Give usbd_do_request_flags() an extra argument for the timeout.
In order of importance:
* Make ugen use updated frlengths.
* More tests for NULL pipes.
* Generate better error codes on bulk write.
* Error messages in general.
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

USB WebCams, using a patch from Peter Housel.
With this change ugen, and with Peter's 'vid' program
in ports/graphics/vid, we can capture single images from USB Cameras
using the OmniVision OV511 chipset (including some models of the
Creative WebCam 3)
NetBSD merged in Peter's patch to their ugen.c file
several months ago, so this brings us back in line.

- Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the
following improvements:
o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP
quirk. This allows drivers to specify busy waiting only for
certain transfers (namely control transfers for reading/writing
registers and stuff).
o New USBD_FORCE_SHORT_XFER flag can be used to deal with
devices like the ADMtek Pegasus that sense the end of bulk OUT
transfers in a special way (if a transfer is exactly a multiple
of 64 bytes in size, you need to send an extra empty packet
to terminate the transfer).
o usbd_open_pipe_intr() now accepts an interval argument which
can be used to change the rate at which the interrupt callback
routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the
value specified in the device's config data, but drivers can
override it if needed.
- Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions.
- Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all
control transfers. We no longer force the non-tsleep hack for
bulk transfers since these are done asynchronously anyway.
- Removed quirk entry fiddling from if_aue and if_kue since we don't
need it anymore now that we have the USBD_NO_TSLEEP flag.
- Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to
usbd_open_pipe_intr().
- Add a flag to the softc struct in the ethernet drivers to indicate
when a device has been detached, and use this flag to perform
tests to prevent the drivers from trying to do control transfers
if this is the case. This is necessary because calling if_detach()
with INET6 enabled will eventually result in a call to the driver's
ioctl() routine to delete the multicast groups on the interface,
which will result in attempts to perform control transfers. (It's
possible this also happens even without INET6 support enabled.) This
is pointless since we know that if the detach method has been called,
the hardware has been unplugged.
- Changed watchdog timeout routines to just call the driver init routines
to initialize the device states without trying to close and re-open the
pipes. This is partly because we don't want to frob things at interrupt
context, but also because this doesn't seem to work right and I don't
want to panic the system just because a USB device may have stopped
responding.
- Fix aue_rxeof() to be a little smarter about detecting when a double
transfer is needed. Unfortunately, the design of the chip makes it hard
to get this exactly right. Hopefully, this will go away once either
Nick or Lennart finds the bug in the uhci driver that makes this ugly
hack necessary.
- Also sync usbdevs with NetBSD.
- more req[uest]->xfer changes.
- get the corresponding NetBSD Id's right
ohci.c
- move untimeout above print statement
- remove usb_delay that panics the system (tsleep in intr context) when
ohcidebug > 5.
ugen.c
- create the devices for endpoints with make_dev.
uhub.c
- change from using usbdebug to uhubdebug
- add more debugging statements
Cleaning up the code:
- Declare many functions static
- Change variable names to make them more self explanatory
- Change usbd_request_handle -> usbd_xfer_handle
- Syntactical changes
- Remove some unused code
- Other KNF changes
Interrupt context handling
- Change delay to usbd_delay_ms were possible (takes polling mode into
account)
- Change detection mechanism for interrupt context
Add support for pre-allocation DMA-able memory by device driver
Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).
usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.
usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.
usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
come and go.
ohci.c
- Handle the case when a USB transfer is so long that it crosses two
page (4K) boundaries. OHCI cannot do that with a single TD so we make
a chain.
ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer. This makes the driver slightly more
efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
causes printing to fail sometimes.
usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
and if not, complain.
usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
the driver or the usbdi layer.
