Move export callback and context to the end of SSL context

Browse source 
This saves some code when compiling for Thumb, where access to
fields with offset index > 127 requires intermediate address
computations. Frequently used fields should therefore be located
at the top of the structure, while less frequently used ones --
such as the export callback -- can be moved to the back.
