Add lvm_pv_get_property() generic function to obtain value of any pv property.

Browse Source 
Add a generic PV property function to lvm2app, similar to VG function.
Return lvm_property_value and require caller to check 'is_valid' flag
before using the value.  If 'is_valid' is not set, then lvm_errno()
should be used to obtain the specific error.
