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
one. This the wire protocol part of issue 5990.

Set up repo

  $ cat << EOF >> $HGRCPATH
  > [ui]
  > origbackuppath=.hg/origbackups
  > [merge]
  > checkunknown=warn
  > EOF
  $ hg init repo
  $ cd repo
  $ echo base > base
  $ hg add base
  $ hg commit -m "base"

Make a dir named b that contains a file, and a file named d

  $ mkdir -p b
  $ echo c1 > b/c
  $ echo d1 > d
  $ hg add b/c d
  $ hg commit -m "c1"
  $ hg bookmark c1

Peform an update that causes b/c to be backed up

  $ hg up -q 0
  $ mkdir -p b
  $ echo c2 > b/c
  $ hg up --verbose c1
  resolving manifests
  b/c: replacing untracked file
  getting b/c
  creating directory: $TESTTMP/repo/.hg/origbackups/b
  getting d
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark c1)
  $ test -f .hg/origbackups/b/c

Make files named b and d

  $ hg up -q 0
  $ echo b1 > b
  $ echo d2 > d
  $ hg add b d
  $ hg commit -m b1
  created new head
  $ hg bookmark b1

Perform an update that causes b to be backed up - it should replace the backup b dir

  $ hg up -q 0
  $ echo b2 > b
  $ hg up --verbose b1
  resolving manifests
  b: replacing untracked file
  getting b
  removing conflicting directory: $TESTTMP/repo/.hg/origbackups/b
  getting d
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark b1)
  $ test -f .hg/origbackups/b

Perform an update the causes b/c to be backed up again - it should replace the backup b file

  $ hg up -q 0
  $ mkdir b
  $ echo c3 > b/c
  $ hg up --verbose c1
  resolving manifests
  b/c: replacing untracked file
  getting b/c
  creating directory: $TESTTMP/repo/.hg/origbackups/b
  removing conflicting file: $TESTTMP/repo/.hg/origbackups/b
  getting d
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark c1)
  $ test -d .hg/origbackups/b

Cause two symlinks to be backed up that points to a valid location from the backup dir

  $ hg up -q 0
  $ mkdir ../sym-link-target
#if symlink
  $ ln -s ../../../sym-link-target b
  $ ln -s ../../../sym-link-target d
#else
  $ touch b d
#endif
  $ hg up b1
  b: replacing untracked file
  d: replacing untracked file
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark b1)
#if symlink
  $ readlink.py .hg/origbackups/b
  .hg/origbackups/b -> ../../../sym-link-target
#endif

Perform an update that causes b/c and d to be backed up again - b/c should not go into the target dir

  $ hg up -q 0
  $ mkdir b
  $ echo c4 > b/c
  $ echo d3 > d
  $ hg up --verbose c1
  resolving manifests
  b/c: replacing untracked file
  d: replacing untracked file
  getting b/c
  creating directory: $TESTTMP/repo/.hg/origbackups/b
  removing conflicting file: $TESTTMP/repo/.hg/origbackups/b
  getting d
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (activating bookmark c1)
  $ cat .hg/origbackups/b/c
  c4
  $ cat .hg/origbackups/d
  d3
  $ ls ../sym-link-target

Incorrectly configure origbackuppath to be under a file

  $ echo data > .hg/badorigbackups
  $ hg up -q 0
  $ mkdir b
  $ echo c5 > b/c
  $ hg up --verbose c1 --config ui.origbackuppath=.hg/badorigbackups
