nodemap: delete older raw data file when creating a new ones

When we write new full files, it replace an older one with a different name. We
add the associated cleanup for the older file to be removed after the
transaction.

We delete all file matching the expected pattern to give use extra chance to
delete orphan files we might have failed to delete earlier.

Note: eventually we won't rewrite all data for each transaction. This is coming
in later changesets.

Rebase - try to rebase on an applied mq patch:

  $ hg rebase -s 1 -d 3
  abort: cannot rebase onto an applied mq patch
  [255]

Rebase - same thing, but mq patch is default dest:

  $ hg up -q 1
  $ hg rebase
  abort: cannot rebase onto an applied mq patch
  [255]
  $ hg up -q qtip

Rebase - generate a conflict:

  $ hg rebase -s 2 -d 1
  rebasing 2:3504f44bffc0 "P0" (f.patch qbase)
  merging f
  warning: conflicts while merging f! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see hg resolve, then hg rebase --continue)
  [1]

Fix the 1st conflict:

  $ echo mq1r1 > f
  $ hg resolve -m f
  (no more unresolved files)
  continue: hg rebase --continue
  $ hg rebase -c
  rebasing 2:3504f44bffc0 "P0" (f.patch qbase)

Fix the 2nd conflict:

  $ hg resolve -m f
  (no more unresolved files)

  $ hg rebase -c
