mocks: add mocks for all framework files

Mocks are provided for all framework files providing
function prototypes. Other framework files are excluded
as their generated mocks are only stubs, and their inclusion
may mislead that they provide mocked functions when they
do not (macro functions in particular may mislead in this
way, as these can't currently be mocked automatically).
