This patch fixes several issues on SCODE:
1) The extracting tool weren't generating the proper tags for SCODE. This
has almost no effect, since those tags shouldn't be used;
2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700;
3) seek_firmware were wanting an exact match for firmware type. This is
wrong. As result, no SCODE firmware were loaded;
4) A few files were including the wrong file for seeking demod firmwares;
5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware.
However, this weren't documentated. This feature require more testing.

In the pvrusb2 driver, different interfaces (e.g. V4L, DVB) have
different abilities to handle various inputs. While the driver core
can handle them all, the interfaces currently are not able to do this.
Also, due to the fact that the DVB interface is directly touching the
hardware, this limits what the V4L side can possibly do with digital
reception, i.e. it has no means to control the digital tuner. This
change implements a critical new feature in the driver where the
interface instance can declare which inputs it is able to handle. The
driver core then uses this information to narrow the list of legal
input selections based on which interface(s) are active at the moment.
The driver core will also perform an input switch (and consequently a
mode switch) if the new narrowed list doesn't include the current
mode. The overall effect of all of this is that now when a user opens
the DVB interface, then the driver flips to dtv mode and likewise when
the V4L video device is opened, the driver will disallow dtv
selection. This also cleans up the handling of the V4L radio device -
open that device and the driver will narrow to just the radio input.
If the narrowing request results in the null set, e.g. attempting to
narrow to dtv only while streaming analog, then the operation is
disallowed and the caller gets an error. This has the effect of
locking out mutually incompatible interfaces. For example, an attempt
to operate a V4L interface will definitively fail when DVB is active.
Thus we have locking and enforcement between the DVB and V4L sides.
Hopefully at some point in the future we can expand the supported
inputs in each interface, and at that point, the interface can just
declare an expanded set of handled inputs and everything should
continue to work itself out. This is a significant feature; it
finally enables cooperative handling of pvrusb2-driven devices between
DVB and V4L.

Apparently the kernel developers no longer consider it proper
etiquette to use __FUNCTION__; everyone must instead use __func__
(even though it breaks with older compilers). And worse still, actual
effort is being expended to sweep this change throughout the kernel
source tree. Don't these people have better things to do? So...
Completely clean out all use of __FUNCTION__ from the pvrusb2 driver
(it was just in the sysfs interface). I'm not going to use __func__
either. So there.

The pvrusb2 driver was getting had by this scenario:
1. Task A calls kthread_stop() for task B.
2. Before exiting, then Task B calls kthread_stop() for task C.
The problem is, kthread_stop() wants to allocate an internal resource
to itself (i.e. acquire a lock), which won't be released until
kthread_stop() returns. But kthread_stop() won't return until task B
is dead. But task B won't die until it finishes its call to
kthread_stop() for task C, and that will block waiting on the resource
already allocated inside task A. Deadlock.
With the pvrusb2 driver, task A is the caller to pvr_exit(), task B is
the control thread run inside of pvrusb2-context.c, and task C is any
worker thread run inside of pvrusb2-hdw.c.
This problem got introduced by the previous threading setup change,
which was itself an attempt to fix a module tear-down race (which it
actually did fix). The lesson here is that a task being waited on as
part of a kthread_stop() simply cannot be allow to also issue a
kthread_stop() - or we make sure not to issue the enclosing
kthread_stop() until we know that the inner kthread_stop() has
completed first. The solution for the pvrusb2 driver is some hackish
code which changes the main control thread tear down into a two step
process. This then makes it possible to delay issuing the
kthread_stop() on the control thread until after we know that
everything has been torn down first. (And yes, we really need that
kthread_stop() because it's the only way to safely guarantee that a
module-referencing kernel thread has safely returned back out of the
module before we finally remove the module.)

If a disconnect happens before initialization is completed, the
pvrusb2 driver can accidentally touch dangling pointers. The whole
initialization function must be protected by the big_lock, and once
inside that lock, the initialization function should abort if it is
discovered that a disconnect has already taken place.

The pvrusb2 driver - for basically forever - was not enforcing a
proper module tear-down. Kernel threads are used inside the driver
and all must be gone before the module can be safely removed. This
changeset reimplements a chunk of pvrusb2-context.c to enforce this
correctly. Unfortunately this is not a simple fix. The new
implementation also cuts back on kernel thread usage; instead of there
being 1 control thread per instance now it's just 1 control thread
shared by all instances. (By dropping to a single thread then the
module exit function can block on its shutdown and the thread itself
can monitor and cleanly shut down all of the other instances first.)

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.
