OK - the flags are really there only for the FS pool (they are not used
for the netfs or dir).  So for the VZ pool I'll only check that they
aren't provided, IOW:

   virCheckFlags(0, -1);

Just so you're aware, here's my plan of action. I've posted three
patches which will make a couple of the *_fs.c pool API's common/local
and *all* of the *_fs.c volume API's local.  I've followed the naming of
the exist vir*Backend*Local APIs (upload, download, and wipe):

Once that series is ACK'd/pushed - I'll update these changes to follow
on. In the end there will be 4 patches and they will be much smaller
than what's here now.
