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 the ability to access a hidden revision on a server
========================================================

#require serve

  $ . $TESTDIR/testlib/obsmarker-common.sh
  $ cat >> $HGRCPATH << EOF
  > [phases]
  > # public changeset are not obsolete
  > publish=false
  > [experimental]
  > evolution=all
  > [ui]
  > logtemplate='{rev}:{node|short} {desc} [{phase}]\n'
  > EOF

Setup a simple repository with some hidden revisions
----------------------------------------------------

Testing the `served.hidden` view

  $ hg init repo-with-hidden
  $ cd repo-with-hidden

  $ echo 0 > a
  $ hg ci -qAm "c_Public"
  $ hg phase --public
  $ echo 1 > a
  $ hg ci -m "c_Amend_Old"
  $ echo 2 > a
  $ hg ci -m "c_Amend_New" --amend
  $ hg up ".^"
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 3 > a
  $ hg ci -m "c_Pruned"
  created new head
  $ hg debugobsolete --record-parents `getid 'desc("c_Pruned")'` -d '0 0'
  obsoleted 1 changesets
  $ hg up ".^"
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 4 > a
  $ hg ci -m "c_Secret" --secret
  created new head
  $ echo 5 > a
  $ hg ci -m "c_Secret_Pruned" --secret
  $ hg debugobsolete --record-parents `getid 'desc("c_Secret_Pruned")'` -d '0 0'
  obsoleted 1 changesets
  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ hg log -G -T '{rev}:{node|short} {desc} [{phase}]\n' --hidden

Test the feature
================

Check that the `served.hidden` repoview
---------------------------------------

  $ hg -R repo-with-hidden serve -p $HGPORT -d --pid-file hg.pid --config web.view=served.hidden
  $ cat hg.pid >> $DAEMON_PIDS

changesets in secret and higher phases are not visible through hgweb

  $ hg -R repo-with-hidden log --template "revision:    {rev}\\n" --rev "reverse(not secret())"
  revision:    2
  revision:    0
  $ hg -R repo-with-hidden log --template "revision:    {rev}\\n" --rev "reverse(not secret())" --hidden
  revision:    3
  revision:    2
  revision:    1
  revision:    0
  $ get-with-headers.py localhost:$HGPORT 'log?style=raw' | grep revision:
  revision:    3
  revision:    2
  revision:    1
  revision:    0

  $ killdaemons.py
