+ Optimise Cortex-M4F ports by inlining some critical section macros.
+ Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h.
+ Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked.
