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.

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.

Move check on frame size after the device is opened and after
device_try_init() is attempted. If the provided size value is 0x0,
perform a VIDIOC_G_FMT ioctl() on the device, which sets size to the
current settings.
