strip: don't use "full" and "partial" to describe bundles

The partial bundle is not a subset of the full bundle, and the full
bundle is not full in any way that i see. The most obvious
interpretation of "full" I can think of is that it has all commits
back to the null revision, but that is not what the "full" bundle
is. The "full" bundle is simply a backup of what the user asked us to
strip (unless --no-backup). The "partial" bundle contains the
revisions we temporarily stripped because they had higher revision
numbers that some commit that the user asked us to strip.

The "full" bundle is already called "backup" in the code, so let's use
that in user-facing messages too. Let's call the "partial" bundle
"temporary" in the code.
