These were previously written in very convoluted C which had to deal with parsing the crazy output of the "lvm" command. In fact the parsing was so complex that it was generated by the generator. It's easier to do this in OCaml. These are basically legacy APIs. They cannot be expanded and LVM already supports many more fields. We should replace these with APIs for getting single named fields from LVM.
