[media] as102: map URB DMA addresses in the driver

On a set-top-box based on the Broadcom 7405 SoC (MIPS), the Abilis as102 driver
causes a kernel oops while trying to map the URB stream buffers DMA addresses:

CPU 0 Unable to handle kernel paging request at virtual address 007b9900,

On other boxes based on older SoCs (7401) this doesn't happen, so it looks like
a bug in the kernel specific to MIPS SMP. This issue has been reproduced on
several kernel versions from 2.6.18 to 3.1.0.

Since the base DMA address and the offsets are known, it is possible to map
the DMA addresses of the URB buffers directly in the driver. This workaround
fixes the problem and has been tested on both MIPS and x86 CPUs with success.

By the way, with this fix the driver works perfectly fine on the set-top-box:
both UHF and VHF frequencies are tuned without problems, and zapping is quite
fast. SNR and signal strength reports seems to work fine, too.

The only remaining problem (on both the PC and the set-top-box) is that after
a soft reboot the device is not recognized again by the kernel. It requires
a power cycle (or a manual unplug/replug) to be recognized again. So probably
the device state is not reset properly at shut-down.

[media] em28xx: pre-allocate DVB isoc transfer buffers

On MIPS/ARM set-top-boxes, as well as old x86 PCs, memory allocation failures
in the em28xx driver are common, due to memory fragmentation over time, that
makes impossible to allocate large chunks of coherent memory.
A typical system with 256/512 MB of RAM fails after just 1 day of uptime (see
the old thread for detailed reports and crashlogs).

In fact, the em28xx driver allocates memory for USB isoc transfers at runtime,
as opposite to the dvb-usb drivers that allocates the USB buffers when the
device is initialized, and frees them when the device is disconnected.

Moreover, in digital mode the USB isoc transfer buffers are freed, allocated
and cleared every time the user selects a new channel, wasting time and
resources.

This patch solves both problems by allocating DVB isoc transfer buffers in
em28xx_usb_probe(), and freeing them in em28xx_usb_disconnect().
In fact, the buffers size and number depend only on the max USB packet size
that is parsed from the USB descriptors in em28xx_usb_probe(), so it can
never change for a given device.

This approach makes no sense in analog mode (as the buffer size depends on
the alternate mode selected at runtime), the patch creates two separate sets
of buffers for digital and analog modes.

For digital-only devices, USB buffers are created when the device is probed
and freed when the device is disconnected.
For analog-only devices, nothing changes: isoc buffers are created at runtime.
For hybrid devices, two sets of buffers are maintained: the digital-mode
buffers are created when the device is probed, and freed when the device is
disconnected; analog-mode buffers are created/destroyed at runtime as before.
So, in analog mode, digital and analog buffers coexists at the same time: this
can be justified by the fact that digital mode is by far more commonly used
nowadays, so it makes sense to optimize the driver for this use case scenario.

The patch has been tested in the last few days on a x86 PC and a MIPS
set-top-box, with the PCTV 290e (digital only) and the Terratec Hybrid XS
(hybrid device). With the latter, I switched several times between analog and
digital mode (Kaffeine/TvTime) with no issue at all.
I unplugged/plugged the devices several times with no problem.
Also, after over 3 days of normal usage in the MPIS set-top-box, the PCTV 290e
was still up and running.

[media] cx22702: Fix signal strength

The signal strength value returned is not quite correct, it decreases
when I increase the gain of my antenna, and vice versa. It also
doesn't span over the whole 0x0000-0xffff range. Compute a value which
at least increases when signal strength increases, and spans the whole
allowed range.

In practice I get 67% with my antenna fully amplified and 51% with
no amplification. This is close enough to what I get on my other
DVB-T adapter with the same antenna.

[media] V4L: Add JPEG compression control class

The V4L2_CID_JPEG_CLASS control class is intended to expose various
adjustable parameters of JPEG encoders and decoders. Following controls
are defined:

 - V4L2_CID_JPEG_CHROMA_SUBSAMPLING,
 - V4L2_CID_JPEG_RESTART_INTERVAL,
 - V4L2_CID_JPEG_COMPRESSION_QUALITY,
 - V4L2_CID_JPEG_ACTIVE_MARKER.

This covers only a part of relevant standard specifications. More
controls should be added in future if required.

The purpose of V4L2_CID_JPEG_CLASS class is also to replace some
functionality covered by VIDIOC_S/G_JPEGCOMP ioctls, i.e. the JPEG
markers presence and compression quality control. The applications
and drivers should switch from the ioctl to control based API, as
described in the subsequent patches for the Media API DocBook.

video_device struct), the start and end messages of VIDIOC_LOG_STATUS are
now generated automatically. People tended to forget these, but the v4l2-ctl
tool scans for these messages, and it also makes it easier to read the status
output in the kernel log.

The cx18, ivtv and bttv drivers were changed since they no longer need to
log these start/end messages.

In saa7164 two empty log_status functions were removed.

Also added a helper function to v4l2-ctrl.c that can be used as the
vidioc_log_status callback if all you need to do is to log the current control
values. This is now used by pwc and vivi.

[media] ivtv: add IVTV_IOC_PASSTHROUGH_MODE

With this private ioctl it is possible to use the ivtv decoder without
requiring the dvb/video.h and dvb/audio.h headers.

Eventually support for those DVB APIs will be dropped from ivtv.

[media] v4l2-ctrls: add new controls for MPEG decoder devices

As discussed during the 2011 V4L-DVB workshop we want to create a proper V4L2
decoder API that replaces the DVBv5 API that has been used until now.

This adds the four controls necessary to be able to switch ivtv over to this
new API.
