Markus Heiser 4845183128 [mod] don't dump traceback of SearxEngineResponseException on init
When initing engines a "SearxEngineResponseException" is logged very verbose,
including full traceback information:

    ERROR:searx.engines:yggtorrent engine: Fail to initialize
    Traceback (most recent call last):
      File "share/searx/searx/engines/__init__.py", line 293, in engine_init
        init_fn(get_engine_from_settings(engine_name))
      File "share/searx/searx/engines/yggtorrent.py", line 42, in init
        resp = http_get(url, allow_redirects=False)
      File "share/searx/searx/poolrequests.py", line 197, in get
        return request('get', url, **kwargs)
      File "share/searx/searx/poolrequests.py", line 190, in request

    searx.exceptions.SearxEngineCaptchaException: Cloudflare CAPTCHA, suspended_time=1296000

For SearxEngineResponseException this is not needed.  Those types of exceptions
can be a normal use case.  E.g. for CAPTCHA errors like shown in the example
above. It should be enough to log a warning for such issues:

    WARNING:searx.engines:yggtorrent engine: Fail to initialize // Cloudflare CAPTCHA, suspended_time=1296000

Marc Abonce Seguin 9b6ffed061 fix fetch_languages for bing
Bing has a list of regions that it supports and some of these regions
may have more than one possible language.

In some cases, like Switzerland, these languages are always shown as
options, so there is no issue. But in other cases, like Andorra, Bing
will only show one language at the time, either the region's default or
the request's language if the latter is supported by that region.

For example, if the HTTP request is in French, Andorra will appear as
fr-AD but if the same page is requested in any other language Andorra
will appear as ca-AD.

This is specially a problem when Bing assumes that the request is in
English because it overrides enough language codes to make several major
languages like Arabic dissappear from the languages.py file.

To avoid that issue, I set the Accept-Language header to a language
that's only supported in one region to hopefully avoid these overrides.

Alexandre Flament ca93a01844 [mod] dynamically set language_support variable
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.

Alexandre Flament d703119d3a [enh] add raise_for_httperror
check HTTP response:
* detect some comme CAPTCHA challenge (no solving). In this case the engine is suspended for long a time.
* otherwise raise HTTPError as before

the check is done in poolrequests.py (was before in search.py).

update qwant, wikipedia, wikidata to use raise_for_httperror instead of raise_for_status

a01200356 c3daa08537 [enh] Add onions category with Ahmia, Not Evil and Torch
Xpath engine and results template changed to account for the fact that
archive.org doesn't cache .onions, though some onion engines migth have
their own cache.

Disabled by default. Can be enabled by setting the SOCKS proxies to
wherever Tor is listening and setting using_tor_proxy as True.

Requires Tor and updating packages.

To avoid manually adding the timeout on each engine, you can set
extra_proxy_timeout to account for Tor's (or whatever proxy used) extra
time.

Noémi Ványi e3282748d0 add display_error_messages option to engine settings
A new option is added to engines to hide error messages from users. It
is called `display_error_messages` and by default it is set to `True`.
If it is set to `False` error messages do not show up on the UI.

Keep in mind that engines are still suspended if needed regardless of
this setting.

Make Python 3 able to read settings files with Unicode characters
SearX currently doesn't start up when run with Python 3 as it tries to parse the
settings.yml file with ASCII codecs.
There are similar problems with engines_languages.json and currencies.json
Python 3 requires that files with Unicode characters be read with a 'b' flag.
This also works with Python 2 and hence can be integrated into the main source
code.

Tested with the latest Python 3.6.4rc1 on Debian unstable.

Alexandre Flament 01e2648e93 Simplify search.py, basically updated PR #518
The timeouts in settings.yml is about the total time (not only the HTTP request but also the prepare the request and parsing the response)
It was more or less the case before since the threaded_requests function ignores the thread after the timeout even the HTTP request is ended.

New / changed stats :
* page_load_time : record the HTTP request time
* page_load_count: the number of HTTP request
* engine_time : the execution total time of an engine
* engine_time_count : the number of "engine_time" measure

The avg response times in the preferences are the engine response time (engine_load_time / engine_load_count)

To sum up :
* Search.search() filters the engines that can't process the request
* Search.search() call search_multiple_requests function
* search_multiple_requests creates one thread per engine, each thread runs the search_one_request function
* search_one_request calls the request function, make the HTTP request, calls the response function, extends the result_container
* search_multiple_requests waits for the the thread to finish (or timeout)
