On some hardware (au0828/au8522), the hardware is broken with
regards to the initial pulse detection. So, the driver needs to
produce a fake start pulse. That limits the acceptable protocols,
as it is not possible to produce a fake pulse that would cover
all supported protocols.
So, allow the driver to explicitly set the allowed protocols.
If the driver doesn't specify, keep the old behavior.

Some vendors have their on keymap table that are used on
all (or almost all) models for that vendor.
So, instead of specifying the keymap table per USB ID,
let's use the Vendor ID's table by default.
At the end, this will mean less code to be added when newer
devices for those vendors are added.
Of course, if rc_map is specified per board, it takes
precedence.

This tries to make them more like other remotes, and/or

Notably, the (>>) button is made KEY_FASTFORWARD, which is the
correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD,
something else entirely.)
Likewise, KEY_STOP is the Sun keyboard "interrupt program" key;
the media key is KEY_STOPCD.
A restriction is that I try to avoid keycodes above 255, as the X11

Now that the protocol is part of the scancode, it is pretty easy to merge
the rc5 and streamzap decoders. An additional advantage is that the decoder
is now stricter as it waits for the trailing silence before determining that
a command is a valid rc5/streamzap command (which avoids collisions that I've
seen with e.g. Sony protocols).

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.
This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there

the code at img-ir-nec.c to use the order used by the other NEC decoders.
The original patch ignored the fact that NEC32 scancodes are generated not
only in the NEC raw decoder but also directly in some drivers. Whichever
approach is chosen it should be consistent across drivers and this patch
needs more discussion.
Furthermore, I'm convinced that we have to stop playing games trying to

The JVC timings included timings intended for the secondary decoder
(which matches messages with no leader), however they were in the wrong
part of the timings structure, repeating s00 and s01 rather than being
in s10 and s11.
Distinct repeat timings can't be properly supported yet for JVC anyway
since the scancode callback cannot determine which decoder matched the
message, so for now remove these timings and don't bother to enable the
secondary decoder.

When either of the normal or wakeup filter protocols are changed,
refresh the corresponding scancode filter, i.e. try and set the same
scancode filter with the new protocol. If that fails clear the filter
instead.
If no protocol was selected the filter is just cleared, and if no
s_filter callback exists the filter is left unmodified.
Similarly clear the filter mask when the filter is set if no protocol is
currently selected.
This simplifies driver code which no longer has to explicitly worry
about modifying the filter on a protocol change. This also allows the
change_wakeup_protocol callback to be omitted entirely if there is only
a single available wakeup protocol at a time, since selecting no
protocol will automatically clear the wakeup filter, disabling wakeup.
