bundles: do not overwrite existing backup bundles (BC)

Previously, a backup bundle could overwrite an existing bundle and cause user
data loss. For instance, if you have A<-B<-C and strip B, it produces backup
bundle B-backup.hg. If you then hg pull -r B B-backup.hg and strip it again, it
overwrites the existing B-backup.hg and C is lost.

The fix is to add a hash of all the nodes inside that bundle to the filename.
Fixed up existing tests and added a new test in test-strip.t

Test that the internal linear merging works correctly
(both heads are stripped to keep pairing of revision number and commit log)

  $ hg update -q -C 2
  $ hg strip 3 4
  saved backup bundle to $TESTTMP/repo/.hg/strip-backup/9530e27857f7-backup.hg (glob)
  $ mv .hg/strip-backup/9530e27857f7-backup.hg $TESTTMP

(internal linear merging at "hg pull --update")
