unified vector table initialization
the cortex generic interrupts get moved to lib/cm3/vector.c, the platorms' individual irq names, initialization and handler prototypes go to platoform specific irq.h files. as the vector.c file heavily depends on platoform specific headers, it can't be built once-and-for-all in lib/cm3/, so there are inclusion stubs in the various architecture dirs; this might be better solved with Makefile / include path handling. one particular file is lib/lpc43xx/vector.c; that platform's initialization code contains an additional section to copy everything from flash to ram (which probably performs better there). that code still resides in the inclusion stub, and gets mashed in using defines. would need a cleaner implementation together with the Makefile solution. this commit contains some files of the upcoming efm32 branch, from which it was cherry-picked. the .bin files produced from before and after this commit only differ in lpc43xx, where the startup sequence was subtly modified.
