More udl(4) devices, from NetBSD.

Make edid_parse() take a device name as extra argument so that the few
messages it may print are tied to the particular device it concerns.

Implement support for framebuffers that don't start on a page boundary.
This happens on the new 14" and 16" Macbook Pro where we deliberately use
a framebuffer that skips the first few lines to avoid "the notch".
The offset of the first pixel is added to struct wsdisplay_fbinfo. The
stride is added as well, mirroring the value returned by the
WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the
future. A compat ioctl is implemented to help the transition. The compat
code will be removed after OpenBSD 7.3 has been released.

Align memory allocation for USB device drivers and USB HC drivers:

In a vanilla setup, this enlarges the USB memory pool.

Nuke all occurrences of usbd_abort_pipe() if it gets called right
before usbd_close_pipe(), since usbd_close_pipe() already takes care
about aborting non-empty pipes.

As investigated by gerhard@ usbdi.c rev. 1.57 did add usbd_abort_pipe()
to usbd_close_pipe(), but the drivers didn't get cleaned up afterwards.

Avoid calling usbd_set_config_no() in *_attach() and let the stack do
it instead.

If anything bad happen due to a malformed descriptor it makes no sense
to try to attach a driver, and bail before probing.

This is similar to the change to avoid calling usbd_set_config_index().

Add a DVACT_WAKEUP op to the *_activate() API. This is called after the
kernel resumes normal (non-cold, able to run processes, etc) operation.
Previously we were relying on specific DVACT_RESUME op's in drivers
creating callback/threads themselves, but that has become too common,
indicating the need for a built-in mechanism.
