Subject: [PATCH] Make code calling proj4 compatible with proj4 5.0 and later

- projects.h is no longer available in 6.0
- use of proj_api.h has to be opted in since 6.0, to be removed in 7.0
- pj_get_list_ref has been renamed proj_list_operations in 5.0
- PJProps is opaque now, its contents can be accessed with proj_pj_info.
  As the contents are no longer global, the const char* from
  GetProjectionName has to be copied into the vtkGeoProjection object.
