Same behaviour behaviour than Whoogle [1]. Only the google engine with the
"Default language" choice "(all)"" is changed by this patch.
When searching for a locate place, the result are in the expect language,
without missing results [2]:
> When a language is not specified, the language interpretation is left up to
> Google to decide how the search results should be delivered.
The query parameters are copied from Whoogle. With the ``all`` language:
- add parameter ``source=lnt``
- don't use parameter ``lr``
- don't add a ``Accept-Language`` HTTP header.
The new signature of function ``get_lang_info()`` is:
lang_info = get_lang_info(params, lang_list, custom_aliases, supported_any_language)
Argument ``supported_any_language`` is True for google.py and False for the other
google engines. With this patch the function now returns:
- query parameters: ``lang_info['params']``
- HTTP headers: ``lang_info['headers']``
- and as before this patch:
- ``lang_info['subdomain']``
- ``lang_info['country']``
- ``lang_info['language']``

The language_support variable is set to True by default,
and set to False in only 5 engines.
Except the documentation and the /config URL, this variable is not used.
This commit remove the variable definition in the engines, and
set value according to supported_languages length: False when the length is 0,
True otherwise.

BTW: make the engines ready for search.checker:
- replace eval_xpath by eval_xpath_getindex and eval_xpath_list
- google_images: remove outer try/except block

Since 1. October 2020 google has changed the 'class' attribute of the HTML
result page.
Fix the xpath expressions and ignore <div class="g" ../> sections which do not
match to title's xpath expression.

Add match_language function in utils to match any user given
language code with a list of engine's supported languages.
Also add language_aliases dict on each engine to translate
standard language codes into the custom codes used by the engine.
