We would like to declare our handles pv_t, vg_t, and lv_t in the external library header lvm.h. However, these are already defined in metadata-exported.h for the use of some of the in-progress liblvm APIs. Thus, we cannot both define them in lvm.h and include metadata-exported.h in the external library C files. We could use preprocessor tricks (#ifndef) but for now we just avoid the include.
