Add new event types for timeout & carrier report
Move timeout handling from ir_raw_event_store_with_filter to
ir-lirc-codec, where it is really needed.
Now lirc bridge ensures proper gap handling.
Extend lirc bridge for carrier & timeout reports
Note: all new ir_raw_event variables now should be initialized
like that: DEFINE_IR_RAW_EVENT(ev);
To clean an existing event, use init_ir_raw_event(&ev);

Currently, jvc decoder will attempt misdetect next press as a repeat
of last keypress, therefore second keypress isn't detected.

This patch moves the state from each raw decoder into the
ir_raw_event_ctrl struct.
This allows the removal of code like this:
spin_lock(&decoder_lock);
list_for_each_entry(data, &decoder_list, list) {
if (data->ir_dev == ir_dev)
break;
}
spin_unlock(&decoder_lock);
return data;
which is currently run for each decoder on each event in order
to get the client-specific decoding state data.
In addition, ir decoding modules and ir driver module load
order is now independent. Centralizing the data also allows
for a nice code reduction of about 30% per raw decoder as
client lists and client registration callbacks are no longer
necessary (but still kept around for the benefit of the lirc
decoder).
Out-of-tree modules can still use a similar trick to what
the raw decoders did before this patch until they are merged.

With the current logic, each raw decoder needs to add a copy of the exact
same sysfs code. This is both unnecessary and also means that (re)loading
an IR driver after raw decoder modules have been loaded won't work as
expected.
This patch moves that logic into ir-raw-event and adds a single sysfs
file per device.
Reading that file returns something like:
"rc5 [rc6] nec jvc [sony]"
(with enabled protocols in [] brackets)
Writing either "+protocol" or "-protocol" to that file will
enable or disable the according protocol decoder.
An additional benefit is that the disabling of a decoder will be
remembered across module removal/insertion so a previously
disabled decoder won't suddenly be activated again. The default
setting is to enable all decoders.
This is also necessary for the next patch which moves even more decoder
state into the central raw decoding structs.

Rather than registering all IR protocol decoders as enabled when bringing
up a new device, only enable the IR protocol decoder that matches the
keymap being loaded. Additional decoders can be enabled on the fly by
those that need to, either by twiddling sysfs bits or by using the
ir-keytable util from v4l-utils.
Functional testing done with the mceusb driver, and it behaves as expected,
only the rc6 decoder is enabled, keys are all handled properly, etc.
