validators: remove unneeded M/StateObj classes

The M class is actually a wrapper around formencode.api.Validator.message,
inserting a translator into the 'state' object. Setting a translator into
the state object is indeed what is mentioned in the formencode docs.

But, if you work this way, the custom state should be set both for custom
validators, as well as for validators that are simple wrappers around
formencode's default validators (for example wrappers that just set a custom
message string). And the latter is what Kallithea is currently _not_ doing.

Also, when using formencode.api.Validator.message correctly, you should not
use the translator function _ on your validator strings manually.

Remove the inconsistency in Kallithea validators as follows:
- remove M and StateObj classes
- replace the usage of M by direct calls to self.message (which is now no
longer in charge of translating but simply of mapping a keyword onto the
right message)
- translation will be done by explicit _ calls at Kallithea side, so that
formencode directly receives translated strings.

.. _troubleshooting:

===============
Troubleshooting
===============

:Q: **Missing static files?**
:A: Make sure either to set the ``static_files = true`` in the .ini file or
   double check the root path for your http setup. It should point to
   for example:
   ``/home/my-virtual-python/lib/python2.7/site-packages/kallithea/public``

|

:Q: **Can't install celery/rabbitmq?**
:A: Don't worry. Kallithea works without them, too. No extra setup is required.
    Try out the great Celery docs for further help.

|

:Q: **Long lasting push timeouts?**
:A: Make sure you set a longer timeout in your proxy/fcgi settings. Timeouts
    are caused by the http server and not Kallithea.

|

:Q: **Large pushes timeouts?**
:A: Make sure you set a proper ``max_body_size`` for the http server. Very often
    Apache, Nginx, or other http servers kill the connection due to to large
    body.

|

:Q: **Apache doesn't pass basicAuth on pull/push?**
:A: Make sure you added ``WSGIPassAuthorization true``.

|

:Q: **Git fails on push/pull?**
:A: Make sure you're using a WSGI http server that can handle chunked encoding
    such as ``waitress`` or ``gunicorn``.

|

:Q: **How can I use hooks in Kallithea?**
:A: It's easy if they are Python hooks: just use advanced link in
    hooks section in Admin panel, that works only for Mercurial. If
    you want to use Git hooks, just install th proper one in the repository,
    e.g., create a file `/gitrepo/hooks/pre-receive`. You can also use
    Kallithea-extensions to connect to callback hooks, for both Git
    and Mercurial.

|

:Q: **Kallithea is slow for me, how can I make it faster?**
:A: See the :ref:`performance` section.

|

:Q: **UnicodeDecodeError on Apache mod_wsgi**
:A: Please read: https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/#if-you-get-a-unicodeencodeerror.

|

:Q: **Requests hanging on Windows**
:A: Please try out with disabled Antivirus software, there are some known problems with Eset Antivirus. Make sure
    you have installed the latest Windows patches (especially KB2789397).
