Rewrite all raster callback functions in C

Description

Most of the raster callback functions are written in PLPGSQL which is unbearably slow.

I suspect rewriting them in C (if we can) would provide faster performance. If not I'll try rewriting them in SQL which I think would make them faster than plpgsql.
