* Rework the convolution template system.

* convolution.c: move local function prototypes to convolution_template.h.

* convolution.c: support for wrap-around in convolutions.
* pipi.c: add the "--wrap" flag to tell libpipi that a given image wraps
around.

* convolution_template.h: split convolution routines into separate functions
for each pixel format.

* convolution.c: fix a small memory leak in the convolution filter.

* blur.c: remove the blurring code and use our generic convolution
routine, which correctly recognises the Gaussian kernel as a separable
filter. As a result, it is now 50% faster because the normalisation
occurs at kernel build time.

* convolution.c: automatically detect when a convolution filter is separable
and switch algorithms to speed up processing.

* convolution.c: generic convolution method. Does not take advantage of
separable kernels yet.
