Andrea Bolognani 94bf7e5d84 build: Extract pod from source files
Instead of embedding the pod information inside the respective
source files, store them in separate files.

This allows us to reduce the number of custom build rules as
most of the information can be inferred for the file name;
moreover, text editors are more likely to use proper syntax
highlighting for standalone pod files.
