This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:
1) I had to enable reporting of a long space at the end of each signal,
or I had weird buffering and keybounce issues.
2) The keymap has been reworked slightly to match actual decoded values,
the first edition was missing the pre-data bits present in the lirc
config file for this remote.
3) There's a whole new decoder included, specifically for the
not-quite-RC5 15-bit protocol variant used by the Streamzap PC
Remote. The decoder, while usable with other recievers (tested with
an mceusb receiver), will only be loaded by the streamzap driver, as
its likely not of use in almost all other situations. This can be
revisited if/when all keytable loading (and disabling of unneeded
protocol decoder engines) is moved to userspace, but for now, I think
this makes the most sense.
Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).
Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.

Switch the code to use new style of getkeycode and setkeycode
methods to allow retrieving and setting keycodes not only by
their scancodes but also by index.

This ports lirc_streamzap.c over to ir-core in-place, to be followed by
a patch moving the driver over to drivers/media/IR/streamzap.c and
enabling the proper Kconfig bits.
Presently, the in-kernel keymap doesn't work, as the stock Streamzap
remote uses an RC-5-like, but not-quite-RC-5 protocol, which the
in-kernel RC-5 decoder doesn't cope with. The remote can be used right
now with the lirc bridge driver though, and other remotes (at least an
RC-6(A) MCE remote) work perfectly with the driver.
I'll take a look at making the existing RC-5 decoder cope with this odd
duck, possibly implement another standalone decoder engine, or just
throw up my hands and say "meh, use lirc"... But the driver itself
should be perfectly sound.
Remaining items on the streamzap TODO list:
- add LIRC_SET_REC_TIMEOUT-alike support
- add LIRC_GET_M{AX,IN}_TIMEOUT-alike support
- add LIRC_GET_REC_RESOLUTION-alike support
All of the above should be trivial to add. There are patches pending to
add this support to ir-core from Maxim Levitsky, and I'll take care of
these once his patches get integrated. None of them are currently
essential though.

Instead of having one big keytable with 2 protocols inside, break it
into two separate tables, being one for NEC and another for RC-5 variants,
and properly identify what variant should be used at the boards entries.

v2: copy of buffer data from userspace done inside this plugin/driver,
keeping the actual drivers minimal, and more flexible in what we can
deliver to them later on (they may be fed from within kernelspace later
on, by an in-kernel IR encoder).

This is the RC6 keymap for the Windows Media Center Edition remotes
that come bundled with MCE/eHome Infrared Remote transceivers. Tested
with 3 different variants of the remote, but its possible there are
still some additional keys missing, but its simple enough to add them
in later...
This patch also adds an IR_TYPE_ALL convenience macro to make life
easier for receivers that support all IR protocols.
v2: fix an erroneous comment that referred to imon devices

This change adds support for Avermedia M733A. The original version for
linux 2.6.31 was sent to me from Avermedia, original author is unknown.
I ported it to current kernels, expanded and fixed key code handling for
RM-K6 remote control, and added an additional pci id also supported.

Pulse-distance is not a protocol, it is a line coding (used by some protocols,
like NEC). Looking at the uses of IR_TYPE_PD, the real protocol seems to be
NEC in all cases (drivers/media/video/cx88/cx88-input.c is the only user).
So, remove IR_TYPE_PD while it is still easy to do so.

A few hardware Remote Controller decoders, even using a standard protocol,
aren't able to provide the entire scancode. Due to that, the capability
of using other IR's are limited on those hardware.
Adds a way to indicate to ir-core what are the bits that the hardware
provides, from a scancode, allowing the addition of a complete IR table
to the kernel and allowing a limited support for changing the Remote
Controller on those devices.

The keymaps don't need to be recompiled every time a change at ir-core.h
happens, since it only depends on rc-map defines. By moving those
definitions to the proper header, the code became cleaner, and avoids
needing to recompile all the RC maps every time a non-related change
is introduced.

Instead of using the ugly keymap sequences, use the new rc-*.ko keymap
files. For now, it is still needed to have one keymap loaded, for the
RC code to work. Later patches will remove this depenency.
