[Libguestfs] [PATCH virt-v2v v2 0/2] v2v: Large temporary directory handling.

v1 was here: https://www.redhat.com/archives/libguestfs/2020-April/msg00007.html There's a BZ for this now which I forgot to add to the commit message: https://bugzilla.redhat.com/show_bug.cgi?id=1814611 For v2: - Fix incorrect reference to $TMPDIR in existing manual. - Separate handling for small temporary files and large temporary files. Small temporary files go into $TMPDIR (/tmp). Large files only go into $VIRT_V2V_TMPDIR or $LIBGUESTFS_CACHEDIR or /var/tmp. - Some code simplification, eg. we don't really need to pass a temporary directory parameter to the Python_script module. Rich.
