drm/udl: Inline memcmp() for RLE compression of xfer
As we use a variable length the compiler does not realise that it is a
fixed value of either 2 or 4 bytes. Instead of performing the inline
comparison itself, the compiler inserts a function call to the generic
memcmp routine which is optimised for long comparisons of variable
length. That turns out to be quite expensive...

drm/udl: fix stride issues scanning out stride != width*bpp
When buffer sharing with the i915 and using a 1680x1050 monitor,
the i915 gives is a 6912 buffer for the 6720 width, the code doesn't
render this properly as it uses one value to set the base address for
reading from the vmap and for where to start on the device.
This fixes it by calculating the values correctly for the device and
for the pixmap. No idea how I haven't seen this before now.

drm/udl: initial UDL driver (v4)
This is an initial drm/kms driver for the displaylink devices.
Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.
On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.
This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.
