Implement timed measurement of encoder operation for the first time it
is run. This allows the driver to note when the encoder has been run
successfully for at least 1/4 second. On top of that implement
various bits to ensure that the encoder has been run once before
digital streaming for OnAir devices. This is done via several core
state machine tweaks.

The commands to start / stop USB streaming for an analog device are
fairly standard, owing to the fact that all supported devices
apparently started from the same common reference design. However
with digital mode, the commands seem to vary by vendor. This change
makes that variance more explicit. It also cleans up a related
problem for OnAir devices which prevented digital mode from working at
all.

Numerous places in the driver need to issue simple commands to the FX2
microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously
each place that did this, had to take lock, set up a central buffer,
and call the function to perform the handshake. This change puts
these steps into a single spot. This also has the effect of removing
the need to mess with the control lock from numerous places in the
code.

- Use buffers even if no-one's currently waiting for them (fixes
underrun issues);
- Don't return incomplete/mangled frames at the start of streaming and
in the case of buffer underruns;
- Fix an issue which could cause the driver to write to a buffer that's
been freed after videobuf_queue_cancel is called (exposed by the
previous two fixes - for some reason, ignoring buffers that weren't

There are some cases where nobody is waiting for a buffer. Due to the
lack of check, if you try to abort the userspace app, machine were
hanging, since IRQ were trying to use a buffer that were disallocated.

A spinlock is necessary for queue_cancel to work with every driver in the tree.
Otherwise a race exists between IRQ handlers removing buffers from the queue
and queue_cancel invalidating the queue.

There were a small bug on videobuf-vmalloc that were preventing STREAMOFF to
work. The issue is that vmalloc'ed mmaped memory should only be freed after
being sure that there aren't any mmap usage. Otherwise, the memory remap will
stop working, and the userspace won't receive any frames.
This bug were affecting some userspace applications, like tvtime.
After this patch, tvtime started to work again with the drivers that use
videobuf-vmalloc.

There were some bugs on videobuf-vmalloc.
Basically, remap were called with a wrong parameter. Due to that, a later remap
were needed, generating the need of some hacks on videobuf-vmalloc and
videobuf-core.
This patch fixes the remap and removes the hacks.
TODO:
- V4L2_MEMORY_USERPTR is not implemented yet. This method should be
properly implemented, in order to work with a few userspace applications.
- The driver also doesn't implement V4L2_MEMORY_OVERLAY. This method is used
only by a few applications, and are becaming obsolete, due to the increment
of cpu performance. So, most apps prefer to retrieve data to an internal
buffer, doing some processing like de-interlacing.

- Aborting buffer_filled if no-one's waiting on the waitqueue probably isn't
what we want, since just because no-one's waiting for it now doesn't mean they
wouldn't dequeue it in time. (vivi gets away with this, possibly because it
can fill each buffer much faster.)
- The first BUG_ON(lencopy <= 0); really isn't worth causing a kernel panic

The usage of videobuf-vmalloc allows to cleanup em28xx logic.
Also, it reduced its size by about 5.42% on i386 arch (and about 7.5% on x86_64):
39113 4876 40 44029 abfd old/em28xx.ko
36731 4868 40 41639 a2a7 /home/v4l/master/v4l/em28xx.ko
Also, the preliminary tests, made on a single core 1.5 MHz Centrino showed
that CPU usage reduced from 42%-75% to 28%-33% (reports from "top") command.
A test with time command presented an even better result:
This is the performance tests I did, running code_example to get 1,000 frames
@29.995 Hz (about 35 seconds of stream), tested on a i386 machine, running at
1,5GHz:
The old driver:
$ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example
0:34.21: 8.22s User time, 25.16s Kernel time, 97% CPU used
The videobuf-based driver:
$ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example
0:35.36: 0.01s User time, 0.05s Kernel time, 0% CPU used
Conclusion:
The time consumption to receive the stream where reduced from about 33.38
seconds to 0.05 seconds.

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.
Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.
options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.
With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

Add a waitqueue to wait on when there are no buffers in the buffer queue.
DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen.
Once a buffer has been queued we recheck that the queue is still streaming and
wait on the new buffer's waitqueue while holding the vb_lock. The driver
should come along in a timely manner and put the buffer into its next state
finishing the DQBUF.
By implementing this waitqueue it also brings the videobuf DQBUF up to spec and
it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF:
"By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue."

There are a number of different firmware versions and variants, shipped
together with boards.

The ability to select RF input was a supported feature only available on
Philips TUV1236d and Philips FCV1236d.
This feature, along with support for the tuners that used it,
was moved into the tuner-simple module.
This can now be removed from dvb-pll.
