Fixes Fedora 14 bug: https://bugzilla.redhat.com/show_bug.cgi?id=667157
There are a few bugs at the code that generates the scancode at dib0700:
- RC keycode is wrong (it outputs a 24 bits keycode);
- NEC extended outputs a keycode that have endiannes issues;
- keycode tables for NEC extended remotes need to be updated.
The last issue need to be done as we get reports, as we don't have
the complete NEC-extended keycodes at the dibcom table.
This patch fixes the first two issues.

This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.
This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.
The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()

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.

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.

This is a big patch, yet trivial. It just move the RC properties
to a separate struct, in order to prepare the dvb-usb drivers to
use rc-core. There's no change on the behavior of the drivers.
With this change, it is possible to have both legacy and rc-core
based code inside the dvb-usb-remote, allowing a gradual migration
to rc-core, driver per driver.

dvb-usb has its own IR handle code. Now that we have a Remote
Controller subsystem, we should start using it. So, remove this
struct, in favor of the similar struct defined at the RC subsystem.
This is a big, but trivial patch. It is a 3 line delect, plus
lots of rename on several dvb-usb files.

Userspace is allowed to coalesce events between SYNCs. And since the code
emits UP right after DOWN for the same key, it may be missed
(up+down=nothing). Add an extra sync in between UP and DOWN events to disable
the coalesce.

When firmware 1.20 was introduced, the dib0700 switched from a polling model
using a USB control message, to the messages being delivered on a USB bulk
pipe. The code I originally added would do a blocking read on the pipe with a
50ms timeout. Because the dvb-usb-remote code makes use of the global
workqueue, this resulted in the global workqueue being blocked 50% of the
time. Also, the synchronous urb_bulk_msg() call would burn excess CPU time
(reflected as an abnormal increase in the system's load average when devices
were connected).
Rework the logic so that we now setup an asynchronous callback on the bulk
pipe, so that we now only handle RC data when it arrives on the pipe. Note
that we provide a stub function for the RC polling callback so that we can
continue to leverage the shared code in dvb-usb-rc for the setting up of the
input device.

The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's
i2c implementation where it did not properly support a single i2c read request
(sending it as an i2c write request instead). Version 1.20 of the firmware
added support for a new i2c API which supported such requests.
This change defaults to fw 1.20 for all devices, but does not default to using
the new i2c API (since initial testing suggests problems interacting with the
mt2060). Maintainers can enable the use of the new i2c API by putting
the following into their frontend initialization:
struct dib0700_state *st = adap->dev->priv;
st->fw_use_new_i2c_api = 1;
Also note that the code expects i2c repeated start to be supported. If the
i2c slave does not support repeated start, i2c messsages should have the
I2C_M_NOSTART flag set.
Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new
firmware fixing the issue as well as example i2c code utilizing the interface.

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.

This patch enables support for repeating last event when a key is holded
down with dib0700 devices. It works with rc5 and nec remotes.
It also fixes an annoying bug that floods kernel log with "Unknown key"
messages after each keypress. This happened because the driver was not
resetting infrared register after each poll so it kept polling last key
even if nothing was being pressed. Fixing this, (calling rc_setup after
each poll), permits to implement key repeat.

When trying to use a Hauppauge Nova-T Stick on a big-endian architecture
(such as powerpc) no frontend can be attached.
The attached patch fixes this problem by removing two lines in
dib0700_ctrl_rd() that try to correct the endianess on two values that
already are correct:
- /* think about swapping here */
- value = le16_to_cpu(value);
- index = le16_to_cpu(index);
