Updated the core prio handling accordingly and set the flag in the three

V4L2 subdevices are media entities. As such they need to inherit from
(include) the media_entity structure.
When registering/unregistering the subdevice, the media entity is
automatically registered/unregistered. The entity is acquired on device
open and released on device close.

The pointer will later be used to register/unregister media entities
when registering/unregistering a v4l2_subdev or a video_device.
With the introduction of media devices, device drivers need to store a
pointer to a driver-specific structure in the device's drvdata.
v4l2_device can't claim ownership of the drvdata anymore.
To maintain compatibility with drivers that rely on v4l2_device storing
a pointer to itself in the device's drvdata, v4l2_device_register() will
keep doing so if the drvdata is NULL.

Renamed has_new to is_new.
Drivers can use the is_new field to determine if a new value was specified
for a control. The v4l2_ctrl_handler_setup() must always set this to 1 since
the setup has to force a full update of all controls.

This patch allows this device successfully to show video, at least from
its composite input.
I have no information about the true hardware contents of this device and so
this patch is based solely on fiddling with things until it worked. The
chip appears to be em2860, and the closest device with equivalent inputs
is the Typhoon DVD Maker. Copying the settings for that device appears
to do the trick. That's what this patch does.

Don't hold the lock before unregistering the device, since when the
device is unregistered the datastruct containing the lock may be freed
(if the refcount went to 0).

Drivers can optionally set a pointer to a mutex in struct video_device.
The core will use that to lock before calling open, read, write, unlocked_ioctl,
poll, mmap or release.
Updated the documentation as well and ensure that v4l2-event knows about the
lock: it will unlock it before doing a blocking wait on an event and relock it
afterwards.
Ensure that the 'video_is_registered' check is done when the lock is held:
a typical disconnect will take the lock as well before unregistering the
device nodes, so to prevent race conditions the video_is_registered check
should also be done with the lock held.

Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.

This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.
The stick has been tested succesfully with both VSB_8 and QAM_256 signals.
Its using lgdt3304 support added to the lgdt3305 driver by a prior patch,
rather than the current lgdt3304 driver, as its severely lacking in
functionality by comparison (see said patch for details).
