repoview: introduce a filter for serving hidden changesets

There are multiple usecase for being able to explicitly view or pull obsolete
from a server. We need to be able to do so without exposing the secret
changesets. We introduces a dedicated repository "view" to do so. Way to expose
this "view" to the user will come later.

To keep a behavior consistent with expected client/server behavior, the general
idea is for the obsolete access to be explicitly requested by the code
generating the request. In addition, the will be server side configuration to
restrict the access to this feature.

Test hg log changeset printer external hook

  >     description = ctx.description().strip().splitlines()[0]
  >     self.ui.write(b"%s:     %s\n" % (brot13(b"summary"),

Prepare the repository

  $ hg init empty
  $ cd empty
  $ touch ROOT
  $ hg commit -A -m "Root" ROOT

  $ touch a b c
  $ hg commit -A -m "Add A, B, C" a b c

Check the log

  $ hg log --config extensions.t=$TESTTMP/logexthook.py

Check that exthook is working with graph log too

  $ hg log -G --config extensions.t=$TESTTMP/logexthook.py
