Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers.  The new
function pointers enable optimised implementations of the filters.

4% faster VP6 decoding on Cortex-A8.

The normal byteswap functions might use inline asm which is suboptimal
with constants (and cannot be used in static initialisers), so special
macros for constants only is needed.

We should not rely on the gcc __builtin_constant_p() test since it is
not always available.

on the type of IFF file you read), better handle odd sizes (like RIFF, every
field is padded to word) and handle headerchunks after the BODY chunk.

uint32_t when calling decodeplane32(), this silences a compiler warning.
Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and
calculate the length once before entering the loop instead of during every
iteration (since it doesn't change).

Move check on frame size after the device is opened and after

perform a VIDIOC_G_FMT ioctl() on the device, which sets size to the
current settings.
