backup: fix issue when the backup end up in a different directory

Because of store encoding, we might end up with the backup in a different
directory than the initial copy (for example if the backup path make it cross
the 120 char limit).

This can create crash, especially since 6.4 where backup are used during revlog
split.

Making sure the directory exists fixes these crash We added a test covering this
case.

Strictly speaking, this has always been broken, however the new code in 6.4
triggers it more easily.

============================================================================
Pulling from modern to a non-general delta target (and other related checks)
============================================================================

There is various issue that can arise when we update the code with modern
storage in mind while working on delta processing. So this file is meant for
various scenario that might break in the future or have break in the past.

Setup
=====

Create a modern server with an older clone

  $ cat << EOF >> $HGRCPATH
  > [command-templates]
  > log = "{desc} {tags}\n"
  > EOF

  $ hg init server

  $ hg clone --quiet --pull server client --config format.usegeneraldelta=no
  $ hg debugformat -R client | grep generaldelta
  generaldelta:        no

Create some complexe history

  $ cd server
  $ hg debugbuilddag -n '.+3:a$.+5:b/a:k$.+7:c/b:l$.+6:d/a:m<k+6/l+1/m'
  $ hg log -G
