Add a generic VG property function to lvm2app. Call the internal library vg_get_property() function. Strings are dup'd internally. Rework lvm_vg_get_property to return lvm_property_value and require caller to check 'is_valid' flag. If !is_valid, the caller can check lvm_errno() for the specific error. Create a 'get_property' function, local to lvm2app, that factors out most of the common code that copies the components of lvm_property_type into lvm_property_value. This allows for a 1-line function for each of the generic property functions exported by lvm2app.
