server: allow customizing the default repo filter

hgweb has the (undocument) configuration option web.view that allows
restricting visible revisions to immutable. This is useful for serving
the same storage as publishing and non-publishing repo. Add the new
server.view option to serve the same purpose by changing the default
behavior of `getdispatchrepo`. Drop the hard-coded 'served' filter in the
batch handler of v1 of the wire proto, this is a left-over from the days
before `getdispatchrepo` existed.

Testing narrow clones when changesets modifying a matching file exist on
multiple branches

  $ . "$TESTDIR/narrow-library.sh"

  $ hg init master
  $ cd master
  $ cat >> .hg/hgrc <<EOF

  $ hg branch default

  >   hg commit -m "Add $x"

  $ hg branch release-v1
  marked working directory as branch release-v1
  (branches are permanent and global, did you want a bookmark?)
  $ hg commit -m "Start release for v1"

  $ hg heads -T '{rev} <- {p1rev} ({branch}): {desc}\n'
  42 <- 41 (release-v2): Hotfix 9 in v2
  36 <- 35 (default): Update 10 to v3
  25 <- 24 (release-v1): Hotfix 5 in v1

  $ cd ..

We now have 3 branches: default, which has v3 of all files, release-v1 which
has v1 of all files, and release-v2 with v2 of all files.

Narrow clone which should get all branches

  $ cd narrow

Narrow clone the first file, hitting edge condition where unaligned
changeset and manifest revnums cross branches.
