Also, add some missing strict/warning statements and fix resulting
warnings and refine some comments in the headers of files.

ConfigSpecs of type METHOD should point to setter/getter methods.
If given no argument they should return the previous value.
However, some of our methods do not follow this API and hence
break things when called as getters (w/o arguments). Most of them
are not used anyway so get rid of them and fix the others.
