The zoran driver uses strncpy() in an unsafe way. This patch uses the proper
sizeof()-1 size parameter. Since all strncpy() targets are initialised with
memset() the trailing '\0' is already set. Where std->name was the target for
the strncpy() we overwrote 8 Bytes of the std structure with zeros.

The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.

Videodev now is capable of better handling V4L2 api, by
processing V4L2 ioctls and using callbacks to the driver.
The drivers should be migrated to the newer way and the older
one will be obsoleted soon.

linux/videodev2.h uses types such as __u8 but it fails to include
<linux/types.h>. Within the kernel, that's not a problem because
<linux/time.h> already includes <linux/types.h>. However, there are
user apps that try to include videodev2.h (e.g., ekiga) and at least
on ia64, it causes compilation failures since <linux/types.h> doesn't
get included for any other reason, leaving __u8 etc. undefined. The
attached patch fixes the problem for me.

This adds support for the older (?) Pinnacle PCTV remotes (with all buttons
colored in grey). There's no autodetection for the type of remote, though;
saa7134 defaults to the colored one, to use the grey remote the
"pinnacle_remote=1" option must be passed to the saa7134 module

Currently in /sys/class/dvb/dvbX.demuxY/ we have:
dev
uevent
With the patch, we have (for a PCI DVB device):
dev
device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0
uevent
So userspace tools can (finally) work out which physical device a DVB adapter
refers to. Previously you had to kinda look through dmesg and hope that it
hadn't been dumped out of the buffer. This makes debugging a lot easier if
the system has been up for a long time!
This is done by adding an extra 'struct device *' parameter to
dvb_register_adapter(). It will work with any kind of standard
linux 'device'. Additionally, if someone has an embedded system which does
things differently, they can simply supply 'NULL' and the behaviour will be
as before - the link will simply not appear.

The ioctl DMX_GET_EVENT has never been implemented.
I guess no software is using it because of its lack of implementation.
Future software won't use it, too, because this API doesn't make much
sense the way it is: Frontend events have their own different API.
Scrambling events can't be generated in a useful way by the hardware I
know of.

Some saa7115-based cards use a different crystal frequency and a different
audio clock generation. Add a new VIDIOC_INT_S_CRYSTAL_FREQ command to be
able to set these values.
Also change the default APLL setting to 0. It makes no sense to have the
audio clock independent from the video clock, this can lead to audio/video
synchronization problems. Setting this to 0 is also consistent with the old
saa7114.c source and the way the Hauppauge Windows driver sets it.

Patch from Daniel Jacobowitz
In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext. Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout. Define the magic numbers for iWMMXt in the header file for easier
reference. Include the size of the coprocessor data in the magic numbers.
Also define magic numbers and layout for VFP, not yet saved.
