On newer kernels, a saa7134 board stopped to display TV video output

Turns out that v4l_bound_align_image isn't doing the same bounding

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",

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
