V4L/DVB: videotext: remove this obsolete API

Remove the vtx (aka videotext aka teletext) API from the v4l2 core.
This API was scheduled for removal in kernel 2.6.35.

The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.

In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.

The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

Note that while the mxb board seemingly used the saa5246a driver, in reality

V4L/DVB: cx88: convert core->tvaudio into an enum

Using an enum and removing the default case from switch statements accessing
the value enables the compiler to emit a warning (enabled with -Wall) when an
audio mode is not handled.

This highlights an omission in the function cx88_dsp_detect_stereo_sap()
(in cx88-dsp.c) not handling WW_EIAJ and WW_M.

V4L/DVB: IR/streamzap: functional in-kernel decoding

This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:

1) I had to enable reporting of a long space at the end of each signal,
   or I had weird buffering and keybounce issues.

2) The keymap has been reworked slightly to match actual decoded values,
   the first edition was missing the pre-data bits present in the lirc
   config file for this remote.

3) There's a whole new decoder included, specifically for the
   not-quite-RC5 15-bit protocol variant used by the Streamzap PC
   Remote. The decoder, while usable with other recievers (tested with
   an mceusb receiver), will only be loaded by the streamzap driver, as
   its likely not of use in almost all other situations. This can be
   revisited if/when all keytable loading (and disabling of unneeded
   protocol decoder engines) is moved to userspace, but for now, I think
   this makes the most sense.

Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).

Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.

The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver
preferably using the gspca webcam framework rather then the old usbvideo
framework.

This new gspca sub driver sets a first step in that direction. The ibmcam
driver supports 4 different model webcams. This new driver (for now) only
supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.

Upon reading:
http://www.linux-usb.org/ibmcam/
I learned that the IBM Netcamera Pro I have even though having the same
usb id and the same bcd version is different from the Model 3 cameras
supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
cameras (untested), and the IBM Netcamera Pro. Currently use with the
IBM Netcamera Pro requires a module parameter. I hope to be able to
autodetect which is which in the future.

If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.

To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it.  Instead, send the buffer to
the host and return to userspace.  This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.

This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.

This patch reverts the driver to enabling/disabling the NFC interrupt
mask rather than enabling/disabling the system interrupt.  This cleans
up the driver so that it doesn't rely on interrupts being disabled
within the interrupt handler.

For i.MX21 we keep the current behaviour, that is calling
enable_irq/disable_irq_nosync to enable/disable interrupts.  This patch
is based on earlier work by John Ogness.
