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.

Hauppauge RC-5 tables require the full scancodes. The code at budget-ci
handles it right, however, it request the rc-code to mask them with 0xff,

Currently, for any multi-standard frontend it is assumed that it just
has a single standard capability. This is fine in some cases, but
makes things hard when there are incompatible standards in conjuction.
Eg: DVB-S can be seen as a subset of DVB-S2, but the same doesn't hold
the same for DSS. This is not specific to any driver as it is, but a
generic issue. This was handled correctly in the multiproto tree,
while such functionality is missing from the v5 API update.
http://www.linuxtv.org/pipermail/vdr/2008-November/018417.html
Later on a FE_CAN_2G_MODULATION was added as a hack to workaround this
issue in the v5 API, but that hack is incapable of addressing the
issue, as it can be used to simply distinguish between DVB-S and
DVB-S2 alone, or another X vs X2 modulation. If there are more systems,
then you have a potential issue.
An application needs to query the device capabilities before requesting
any operation from the device.
