Provide functions used in geod in the library instead

It would be nice to be able to use the functions for geodesic calculations (implemented in geod) by linking against libproj.

The python proj bindings (http://code.google.com/p/pyproj) currently includes a copy of the complete proj sources. I've modified it to link agains libproj, but it still needs emess.c, emess.h, geod.c, geodesic.h, geod_for.c, geod_inv.c and geod_set.c.

The patch supplied with ticket #197 makes this feasible. The
API is given at the beginning of geodesic.h. It's possible that
a wrapper needs to be provided to expose an interface more in
the spirit of proj.4, e.g.,

• angles in radians
• how the ellipsoid is specified
• prefix function names with pj_

The geod reimplementation and publishing of a public api for geodesic features is now complete.
