[lvm-devel] [PATCH 5/8] Add list structure definitions for liblvm objects.



- pv_t, vg_t, lv_t, lvseg_t, pvseg_t
- include libdevmapper.h: needed for struct dm_list

These list structures will be needed in later APIs to return a list of
handles to one object, given another object.  For example, lvm_lvs_in_vg()
will return a list of LV handles (lv_t's) given a VG handle (vg_t).  We
need a structure to do this so we define the LV structure, as well as the
other structures at this point.
