52b019b3ed Merge from NetBSD and arrange for FreeBSD's slight differences in
ucom.

This gets my Sanyo SCP-4900 working.

3241be7550 Synchronisation with NetBSD as of 1999/11/16:
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.

8c895d718b Major synchronisation with the NetBSD USB stack:
- Some cleanup and improvements in the uhci and ohci drivers
- Support for plugging and unplugging devices improved
- Now available is bulk transport over OHCI controllers
- Resume and suspend have been temporarily been disabled again.  Proper
  support for it is available in the uhci.c and ohci.c files but I have
  not yet spent the brain cycles to use it.
- OpenBSD now uses the USB stack as well
- Add FreeBSD tags

6d38342e16 Add comments, change variable names to make them consistent (r -> err,
timo_handle -> timeout_handle, p -> pipe, *pipe -> *rpipe, etc.)

114278b089 1) Remove the definition of usb_cdc_generic_descriptor_t. It is
equivalent to usb_descriptor_t

2) Rename USB_CDC_CM_CM_OVER_DATA to USB_CDC_CM_OVER_DATA
