mq: backup local changes in qpush --force

qpush help says the following about --force:
1- When -f/--force is applied, all local changes in patched files will
   be lost.
2- Apply on top of local changes

In practice, qpush --force will attempt to apply the patch on top of
local changes, and on success will merge them in the pushed patch. On
failure, patched files will contain a mix of local changes (where the
patch could not apply) and a mix of patch changes (were it applied). So,
local changes are less lost than entangled with a mass of other changes.

This patch makes qpush --force backup all locally modified files touched
by the next patch being applied. When multiple patches are being pushed,
this logic is repeated for each patch. Note that modified but
successfully patched files are preserved as well.
