This reverts commit
bc52d6eb44de8f19934768d4d10d19fdbdc99950.
On newer kernels, a saa7134 board stopped to display TV video output
properly. After a bisect, I found it as the commit causing the issue.
Turns out that v4l_bound_align_image isn't doing the same bounding
calculation as manually done previously in saa7134_try_fmt_vid_cap.
What isn't equal is the calculation done in clamp align, while
previously it did "f->fmt.pix.width &= ~0x03", clamp_align function
does "Round to nearest aligned value" as stated in the comment, which
yields a different result. If I comment the round calculation in
clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask",
I get it fixed too, because this way the calculation is the same then.

drivers/media/IR/ir-raw-event.c is currently written with the assumption
that all "raw" hardware will generate events only on state change (i.e.
when a pulse or space starts).
However, some hardware (like mceusb, probably the most popular IR receiver
out there) only generates duration data (and that data is buffered so using
any kind of timing on the data is futile).
Furthermore, using signed int's to represent pulse/space durations is a
well-known approach when writing ir decoders.
With this patch:
- s64 int's are used to represent pulse/space durations in ns
- a workqueue is used to decode the ir protocols outside of interrupt context
- #defines are added to make decoders clearer
- decoder reset is implemented by passing a zero duration to the kfifo queue
and decoders are updated accordingly

Instead of the old strategy of handling the events all at once,
this code implements a state machine. Due to that, it handles
individual pulse or space events, validating them against the
protocol, producing a much more reliable decoding.
With the new implementation, the protocol trailer bits are properly

V4L/DVB: ir-common: remove keymap tables from the module
Now that the remote keymaps were broken into separate modules,
get rid of the keycode tables that were hardcoded into ir-common.

V4L/DVB: ir-core: Make use of the new IR keymap modules
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.

V4L/DVB: ir: prepare IR code for a parameter change at register function
A latter patch will reuse the ir_input_register with a different meaning.
Before it, change all occurrences to a temporary name.

V4L/DVB: Break Remote Controller keymaps into modules
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 having all RC tables hardcoded on one file with

V4L/DVB: ir-common: Use macros to define the keytables
The usage of macros ensures that the proper namespace is being used
by all tables. It also makes easier to associate a keytable with
the name used inside the drivers.
