bundle: refactor changegroup prune to be its own function

Moving the prune function to be a non-nested function allows extensions to
control which revisions are allowed in the changegroup. For example, in my
shallow repo extension I want to prevent filelogs from being added to the
bundle.

This also allows an extension to use a filelog implementation that doesn't
have revlog.linkrev implemented.

  $ hg init t
  $ cd t
  $ echo a > a
  $ hg add a
  $ hg commit -m test
  $ rm .hg/requires
  $ hg tip
  abort: index 00changelog.i unknown format 2!
  [255]
  $ echo indoor-pool > .hg/requires
  $ hg tip
  abort: unknown repository format: requires features 'indoor-pool' (upgrade Mercurial)!
  [255]
  $ echo outdoor-pool >> .hg/requires
  $ hg tip
  abort: unknown repository format: requires features 'indoor-pool', 'outdoor-pool' (upgrade Mercurial)!
