chg: replace mercurial.util.recvfds() by simpler pure Python implementation

On Python 3, we have socket.socket.recvmsg(). This makes it possible to receive
FDs in pure Python code. The new code behaves like the previous
implementations, except that it’s more strict about the format of the ancillary
data. This works because we know in which format the FDs are passed.

Because the code is (and always has been) specific to chg (payload is 1 byte,
number of passed FDs is limited) and we now have only one implementation and
the code is very short, I decided to stop exposing a function in
mercurial.util.

Note on terminology: The SCM_RIGHTS mechanism is used to share open file
descriptions to another process over a socket. The sending side passes an array
of file descriptors and the receiving side receives an array of file
descriptors. The file descriptors are different in general on both sides but
refer to the same open file descriptions. The two terms are often conflated,
even in the official documentation. That’s why I used “FD” above, which could
mean both “file descriptor” and “file description”.

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'
  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

  $ 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

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
