Instead of using DVBv3 parameters, rely on DVBv5 parameters to

This driver implements a fake get_bandwidth() callback. In
reallity, the tuner driver won't adjust its low-pass
filter based on a bandwidth, and were just providing a fake
method for demods to read whatever was "set".
This code is useless, as none of the drivers that use
this tuner seems to require a get_bandwidth() callback.
While here, convert set_params to use the DVBv5 way to pass
parameters to tuners.

Instead of just estimating the bandwidth for DVB-C annex A/C,
also fill it at the core for ATSC and DVB-C annex B. This
simplifies the logic inside the tuners, as all non-satellite
tuners can just use c->bandwidth_hz for all supported
delivery systems.
It could make sense to latter use it also for satellite
systems, as several DVB-S drivers have their own calculus.
However, on DVB-S2 the bw estimation is a little more complex,
and the existing drivers have some optimized calculus for
bandwidth. So, let's not touch on it for now.

SYS_DVBC_ANNEX_AC is an alias for SYS_DVBC_ANNEX_A. However,
the first one is incorrect, as not all devices support both.
So, replace its occurrences by the proper value (either
SYS_DVBC_ANNEX_A or both SYS_DVBC_ANNEX_A and SYS_DVBC_ANNEX_C).

There are some issues and miss-behaves at the dvb fe thread:
1) dvb_shutdown_timeout should be dvb_shutdown_timeout * HZ
instead of (dvb_shutdown_timeout * HZ + 1);
2) add a memory barrier to warrant that all CPU's will consider the
new value for release_jiffies;
3) wake up dvb thread also when fepriv->exit == DVB_FE_NO_EXIT.

drivers/media/video/videobuf2-core.c:1099:14: warning: comparison between ‘enum v4l2_buf_type’ and ‘enum v4l2_memory’ [-Wenum-compare]
On all places V4L2_MEMORY_USERPTR is used, it is associated with
q->memory, and not b->type. So, the fix seems obvious.

To get direct access to userspace memory pages vb2 allocator needs to
gather read access on mmap semaphore in the current process.
The same semaphore is taken before calling mmap operation, while
both mmap and qbuf are called by the driver or v4l2 core with
driver's lock held. To avoid a AB-BA deadlock (mmap_sem then
driver's lock in mmap and driver's lock then mmap_sem in qbuf)
the videobuf2 core release driver's lock, takes mmap_sem and then
takes again driver's lock. get_userptr methods are now called with
all needed locks already taken to avoid further lock magic inside
memory allocator's code.

Heuristic that checks if the memory pointer has been changed lacked a check
