files: speed up `hg files` when no flags change display

It's not the first time I see slowness from this command slow down
tools built on top of hg.

The majority of the time is spent merely printing the result before
this change, which is clearly not how it should be (especially since
the computation of the result also looks slow).

Running `hg files` in mozilla-central:

parent revision: 1,260s
this commit: 0,683s
this commit without batching ui.write: 0,931s
this commit replacing the body of the loop with `pass`: 0,566s

This looks like a prime candidate for a rust fast path, but until
then, it seems reasonable to optimize the python.

Test the ability to access a hidden revision on a server

#require serve

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'
  1 new obsolescence markers
  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'
  1 new obsolescence markers
  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 cache pre-warm
--------------------

  $ ls -1 repo-with-hidden/.hg/cache
  branch2
  branch2-base
  branch2-served
  branch2-served.hidden
  branch2-visible
  rbc-names-v1
  rbc-revs-v1
  tags2

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
