f032ed7498 Add lvm_{pv|vg|lv}_get_{uuid|name}.
Caller must free the memory of the uuid / name returned.
This may not be the best memory management policy since it may lead to
memory leaks if the caller has code like this:
if (!lvm_vg_get_name(vg))

Maybe we don't care - if we do we can use pools tied to handles later
or some other scheme.

729f472c04 Add lvm_vg_open() to open an existing VG for reading or writing.
lvm_vg_open() calls internal vg_read() function which is the entry point
for reading an existing VG.  In addition to the mode, we include a 'flags'
parameter for future extensions.
