I see that those functions and the structure defines they are based on
are not currently part of the public api in proj_api.h.  However, they
are available if you include the internal projects.h include file.  I
generally discourage this, but it may still be the expedient thing for
you to do.

I might make sense to move these structure definitions and function
prototypes to proj_api.h if we want to consider them generally available.
