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 a new driver for the Windows Media Center Edition/eHome
Infrared Remote transceiver devices. Its a port of the current
lirc_mceusb driver to ir-core, and currently lacks transmit support,
but will grow it back soon enough... This driver also differs from
lirc_mceusb in that it borrows heavily from a simplified IR buffer
decode routine found in Jon Smirl's earlier ir-mceusb port.
This driver has been tested on the original first-generation MCE IR
device with the MS vendor ID, as well as a current-generation device
with a Topseed vendor ID. Every receiver supported by lirc_mceusb
should work equally well. Testing was done primarily with RC6 MCE
remotes, but also briefly with a Hauppauge RC5 remote, and all works
as expected.
v2: fix call to ir_raw_event_handle so repeats work as they should.

This decoder is also based on a state machine, just like the NEC protocol
decoder. It is pedantic in the sense that accepts only 14 bits. As there
are some variants that outputs less bits, it needs to be improved to also
handle those.

The original Remote Controller approach were very messy: a big file,
that were part of ir-common kernel module, containing 64 different
RC keymap tables, used by the V4L/DVB drivers.
Better to break each RC keymap table into a separate module,
registering them into rc core on a process similar to the fs/nls tables.
As an userspace program is now in charge of loading those tables,
adds an option to allow the complete removal of those tables from
kernelspace.
Yet, on embedded devices like Set Top Boxes and TV sets, maybe the
only available input device is the IR. So, we should keep allowing
the usage of in-kernel tables, but a latter patch should change
the default to 'n', after giving some time for distros to add
the v4l-utils with the ir-keytable program, to allow the table
load via userspace.

Instead of hardcoding the protocols into ir-core, add a register interface
for the IR protocol decoders, and convert ir-nec-decoder into a client of
ir-core.
With this approach, it is possible to dynamically load the needed IR protocols,
and to add a RAW IR interface module, registered as one IR raw protocol decoder.
This patch opens a way to register a lirc_dev interface to work as an userspace
IR protocol decoder.

Split the ir-common into two separate modules:
- ir-core: it is the IR-independent functions;
- ir-common: has the common part used by V4L drivers.

This is the first step of creating a common code for IR that can be
used by other input devices.
For now, keep IR dir at drivers/media, to easy the movement of the IR files,
but later patches may move it to drivers/IR or drivers/input/IR.
No functional changes is done on this patch.
