bundle2: handle compression in _forwardchunks

_forwardchunks is used to compensate for getbundle protocol deficits.
Since it transparently decodes the payload, it also needs to remove the
corresponding compression parameter in case the server decides to send

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported

  $ hg clone -q -u . ah ah6
  $ cd ah6
  $ hg rebase -r '(4+6)::' -d 1

More complex rebase with multiple roots
each root have a different common ancestor with the destination and this is a detach

(setup)

  $ hg clone -q -u . a a8
  $ cd a8
  $ echo I > I
  $ hg add I
  $ hg commit -m I
  $ hg up 4
  1 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo I > J
  $ hg add J
  $ hg commit -m J
  created new head
  $ echo I > K
  $ hg add K
  $ hg commit -m K

Test that rebase is not confused by $CWD disappearing during rebase (issue4121)

  $ hg commit -m 'first source commit'

  $ cd subdir

  $ hg add subfile
  $ hg commit -m 'second source with subdir'

  $ hg rebase -b . -d 1 --traceback

Get back to the root of cwd-vanish. Note that even though `cd ..`
works on most systems, it does not work on FreeBSD 10, so we use an
absolute path to get back to the repository.
