The bt8xx driver only uses the big kernel lock in its dst_ca_ioctl
function and never to serialize against other code, so we can
trivially replace it with a private mutex.

The dvb core only uses the big kernel lock in the open
and ioctl functions, which means it can be replaced with
a dvb specific mutex. Fortunately, all the ioctl functions
go through dvb_usercopy, so we can move the serialization
in there.

As reported by Anton Blanchard <anton@samba.org>, double IR events on
2.6.36-rc2 and a DViCO FusionHDTV DVB-T Dual Express are happening:
[ 1351.032084] ir_keydown: i2c IR (FusionHDTV): key down event, key 0x0067, scancode 0x0051
[ 1351.281284] ir_keyup: keyup key 0x0067
ie one key down event and one key up event 250ms later.
So, we need to increase the repeat timeout, to avoid this bug to hit.
As we're doing it at core, this fix is not needed anymore at dib0700 driver.

As reported by Carlos, Prolink Pixelview SBTVD Hybrid is based on
Conexant cx231xx + Fujitsu 86A20S demodulator. However, both shares
the same USB ID. So, we need to use USB bcdDevice, in order to
properly discover what's the board.
We know for sure that bcd 0x100 is used for a dib0700 device, while
bcd 0x4001 is used for a cx23102 device. This patch reserves two ranges,
the first one from 0x0000-0x3f00 for dib0700, and the second from
0x4000-0x4fff for cx231xx devices.
This may need fixes in the future, as we get access to other devices.

Here a small patch to get a TwinHan VT DST DVB-T card working with
kernels >= 2.6.32. Analogously to
http://linuxtv.org/hg/v4l-dvb/rev/0e735b509163 I had to:
"Fill in the .caps field in struct dst_dvbt_ops (around line 1763) with
all the supported QAM modulation methods to match the capabilities of
the card as implemented in function dst_set_modulation (around line
502). Note that beginning with linux kernel version 2.6.32 the
modulation method is checked (by function dvb_frontend_check_parameters
in file drivers/media/dvb/dvb-core/dvb_frontend.c) and thus tuning fails
if you use a modulation method that is not present in the .caps field."

Rewrites the siano IR implementation. The previous implementation were
non-standard. As such, it has issues if more than one device registers IR,
as there used to have some static constants used during protocol decoding
phase. Also, it used to implement its on RAW decoder, and only for RC5.
The new code uses RC core subsystem for handling IR. This brings several
new features to the driver, including:
- Allow to dynamically replace the IR keycodes;
- Supports all existing raw decoders (JVC, NEC, RC-5, RC-6, SONY);
- Supports lirc dev;
- Doesn't have race conditions when more than one sms IR is
registered;
- The code size for the IR implementation is very small;
- it exports the IR features via /sys/class/rc.

This patch implements change_protocol callback. With this change,
there's no need for an extra modprobe parameter to specify the
protocol. When a table is loaded (either from in-kernel rc-map
tables or via ir-keytable program), the driver will automatically
change the protocol, in order to work with the given table.
