Update sdk headers to export new symbols.

All symbols in installed sdk headers should be explicitly tagged
as exported symbols. Otherwise, to ensure it is not a mistake, one
could write it as something like:
extern /* NOEXPORT */ type name ...;
but the proper procedure really should be to use a non sdk header
(or a "noinst_" one).
  This patch also removes prototypes to some functions that existed
only temporarily.
