bundle2: equate 'UN' with no compression

An upcoming patch will change the "alg" argument passed to this
function from None to "UN" when no compression is wanted.

The existing implementation of bundle2 does not set a "Compression"
parameter if no compression is used. In theory, setting
"Compression=UN" should work. But I haven't audited the code to see if
all client versions supporting bundle2 will accept this.

Rather than take the risk, avoid the BC breakage and treat "UN"
the same as None.

Create repo with old manifest

  $ cat << EOF >> $HGRCPATH
  > [format]
  > usegeneraldelta=yes
  > EOF

  $ hg init existing
  $ cd existing
  $ echo footext > foo
  $ hg add foo
  $ hg commit -m initial

We're using v1, so no manifestv2 entry is in requires yet.

  $ grep manifestv2 .hg/requires
  [1]

Let's clone this with manifestv2 enabled to switch to the new format for
future commits.

  $ cd ..
  $ hg clone --pull existing new --config experimental.manifestv2=1

  adding file changes

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd new

Check that entry was added to .hg/requires.

  $ grep manifestv2 .hg/requires
  manifestv2

Make a new commit.

  $ echo newfootext > foo
  $ hg commit -m new

Check that the manifest actually switched to v2.

  $ hg debugdata -m 0
  foo\x0021e958b1dca695a60ee2e9cf151753204ee0f9e9 (esc)

  $ hg debugdata -m 1

  I\xab\x7f\xb8(\x83\xcas\x15\x9d\xc2\xd3\xd3:5\x08\xbad5_ (esc)

Check that manifestv2 is used if the requirement is present, even if it's
disabled in the config.

  $ echo newerfootext > foo
  $ hg --config experimental.manifestv2=False commit -m newer

  $ hg debugdata -m 2
  \x00 (esc)
  \x00foo\x00 (esc)

Check that we can still read v1 manifests.

  $ hg files -r 0
  foo

  $ cd ..

Check that entry is added to .hg/requires on repo creation

  $ hg --config experimental.manifestv2=True init repo
  $ cd repo
  $ grep manifestv2 .hg/requires
  manifestv2

Set up simple repo

  $ echo a > file1
  $ echo b > file2
  $ echo c > file3
  $ hg ci -Aqm 'initial'
  $ echo d > file2
  $ hg ci -m 'modify file2'

Check that 'hg verify', which uses manifest.readdelta(), works

  $ hg verify
