The ca91cx42 driver currently incorrectly handles master windows, setting
and retrieving the sizing parameters incorrectly. Also, in the slave window
handling, it uses an incorrectly set variable.

Specify Kconfig dependencies, and include warnings for building as a module
udlfb is dependent on FB_DEFERRED_IO, FB_SYS_*, and FB_MODE_HELPERS
Because many kernels do not include defio (which cannot be built
as a module), yet users want to be able to build udlfb as a module later,
udlfb has ifdefs and these dependency warnings to help udlfb build with or
without certain dependencies, but also print warnings for any lost function.
Even though this kind of flexibility isn't common, we've gotten feedback
from a significant portion of users that they were frustrated without it.

Add support for fbdev mmap clients who don't send damage ioctls
Because DisplayLink devices are out on the other end of usb, their
"framebuffer" is just normal system memory. So memory mapped writes
don't automatically trigger anything. So up to this point, standard
fbdev clients who rely on mmap() will get an unchanging screen.
This patch makes udlfb a client of Jaya Kumar's defio framework - which sets
up page fault triggers, and those faults are accumulated and sent to udlfb
on a defferred basis, to process as damage notifications for the framebuffer.
Because this involves more overhead than a notification directly from
the application (e.g. just passing on X DAMAGE extension notifications),
a sysfs attribute is provided by udlfb to control defio support.
/sys/class/graphics/fb*/use_defio - writing a "0" to this file before
calling mmap() causes defio to not be initialized - instead udlfb
will rely on getting damage notifications directly through the damage ioctl.
There are unsolved rendering problems with defio (horizontal dead regions
on framebuffer, that accumulate over time) which still needs a fix.

Rework rendering for improved performance
Approx 10-20% gain avg across several "benchmarks": x11perf, gtkperf, glxgears
Moves from a single pre-alloc'd urb protected by a long-held mutex
To a list of (4) pre-alloc'd urbs which can be dispatched asynchonously
Improved rendering algorithm to hardware with lower CPU consumption,
fewer system memory accesses, and slightly higher compression.
Better scalability to multiple processors, especially with
multiple framebuffers active.

Rework probe to use refcounts and std functions
Because the different parts of the driver (usb, fbdev) tear down
in different orders, the driver previously could crash accessing
data that had already been freed. Refcounting system used to handle.

Add sysfs controls for edid and performance metrics
There are 8 new files exposed in /sys/class/graphics/fb*
edid - returns 128 byte edid blog, suitable for parsing with parse-edid
metrics_bytes_identical
metrics_bytes_rendered
metrics_bytes_sent
metrics_cpu_kcycles_used
metrics_misc
and metrics_reset, which resets all perf metrics to zero
The 6 perf metrics are of type atomic_t.
So these metrics return precise results for short benchmarks, but
any test approx a minute or longer runtime may roll over.

Add functions to pre-allocate and free usb bulk urbs for core render path.
Udlfb currently allocates a single urb, guarded by a mutex, that is a key
bottleneck. Because udlfb sends so much data, preallocation is most efficient.
Functions will be used by new rendering functions in later patches.

libusb, and the in-kernel driver is just getting in the way now and
causing problems. So they have asked that the in-kernel driver be
removed. As the staging driver wasn't quite working anyway, and Mimio
supports their libusb solution for all distros, I am removing the
in-kernel driver.
