The list of strings is used quite frequently and we'd like to reuse this simple structure for report selection support too. Make it part of libdevmapper for general reuse throughout the code. This also simplifies the LVM code a bit since we don't need to include and manage lvm-types.h anymore (the string list was the only structure defined there).
