wireproto: define permissions-based routing of HTTPv2 wire protocol

Now that we have a scaffolding for serving version 2 of the HTTP
protocol, let's start implementing it.

A good place to start is URL routing and basic request processing
semantics. We can focus on content types, capabilities detect, etc
later.

Version 2 of the HTTP wire protocol encodes the needed permissions
of the request in the URL path. The reasons for this are documented
in the added documentation. In short, a) it makes it really easy and
fail proof for server administrators to implement path-based
authentication and b) it will enable clients to realize very early in
a server exchange that authentication will be required to complete
the operation. This latter point avoids all kinds of complexity and
problems, like dealing with Expect: 100-continue and clients finding
out later during `hg push` that they need to provide authentication.
This will avoid the current badness where clients send a full bundle,
get an HTTP 403, provide authentication, then retransmit the bundle.

In order to implement command checking, we needed to implement a
protocol handler for the new wire protocol. Our handler is just
small enough to run the code we've implemented.

Tests for the defined functionality have been added.

I very much want to refactor the permissions checking code and define
a better response format. But this can be done later. Nothing is
covered by backwards compatibility at this point.

(Translations are optional)

#if gettext no-outer-repo

Test that translations are compiled and installed correctly.

Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:

  $ LANGUAGE=pt_BR hg tip
  abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
  [255]

Using a more accommodating encoding:

  $ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
  abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
  [255]

Different encoding:

  $ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
  abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
  [255]

#endif

#if gettext

Test keyword search in translated help text:

  $ HGENCODING=UTF-8 LANGUAGE=de hg help -k Aktualisiert
  Themen:
  
   subrepos Unterarchive
  
  Befehle:
  
   pull   Ruft \xc3\x84nderungen von der angegebenen Quelle ab (esc)
   update Aktualisiert das Arbeitsverzeichnis (oder wechselt die Version)

#endif

Check Mercurial specific translation problems in each *.po files, and
tool itself by doctest

  $ cd "$TESTDIR"/../i18n
  $ $PYTHON check-translation.py *.po
  $ $PYTHON check-translation.py --doctest
  $ cd $TESTTMP

#if gettext

Check i18n cache isn't reused after encoding change:

  $ cat > $TESTTMP/encodingchange.py << EOF
  > from mercurial.i18n import _
  > from mercurial import encoding, registrar
  > cmdtable = {}
  > command = registrar.command(cmdtable)
  > @command(b'encodingchange', norepo=True)
  > def encodingchange(ui):
  >     for encode in (b'ascii', b'UTF-8', b'ascii', b'UTF-8'):
  >         encoding.encoding = encode
  >         ui.write(b'%s\n' % _(b'(EXPERIMENTAL)'))
  > EOF

  $ LANGUAGE=ja hg --config extensions.encodingchange=$TESTTMP/encodingchange.py encodingchange
