[Libguestfs] Should we always do wipefs before mkfs? Discuss ...

In particular comments 2 & 3.

We could change libguestfs's guestfs_mkfs (internally) so it always
does an implicit wipefs on the filesystem.  wipefs is not too onerous --
in particular I believe it only writes to a few chosen areas of the
disk.  Especially considering that we're about to run mkfs anyway
which for some filesystems writes a lot of blocks.

Thoughts?

Rich.
