New APIs: Query the relationship between LVM objects.

These calls allow you to query the relationship between
LVM objects, for example, which PVs contain a VG, or which
LVs are contained in a VG.

See the example / test program 'regressions/test-lvm-mapping.pl'
for an example of how to do this from Perl.
