Dave Wysochanski 83f25cd121 Add most all liblvm 'get' functions needed for anaconda.
Add the most straightforward 'get' functions required for anaconda.
These are the ones that return simple uint64_t values.
The other more complex ones involve the lv_attr bits.  These will
come in a separate patch series since each lv_attr bit will be returned
in a separate API instred of returning the string and requiring the
user to parse it.
