Rename template included sources from .h to _template.c.

There are multiple source files that are #include'd rather than
compiled, as they are used as template for generation of similar code,
like asm-optimised code. Some of these files are right now named with
a .h extension, although they are not header in any reasonable sense.

Rename them so that instead of being named with .h extension they are
named with _template.c as final part.
