Subject: [PATCH 14/27] Introduce the server functionality in the kiwix-lib.

This code is mainly copied from kiwix-tools.

But :
- Move all the response thing in a new class Response.
- This Response class is responsible to handle all the MHD_response
  configuration. This way the server handle a global object and do
  no call to MHD_response*
- Server uses a lot more the templating system with mustache.
  There are still few regex operations (because we need to
  change a content already existing).
- By default, the server serves the content using the id as name.
- Server creates a new Searcher per request. This way, we don't have
  to protect the search for multi-thread and we can do several search
  in the same time.
- search results are not cached, this will allow future improvement in the
  search algorithm.
- the home page is not cached.
- Few more verbose information (number of request served, time spend to
  respond to a request).

TOOD:
 - Readd interface selection.
 - Do Android wrapper.
 - Remove KiwixServer (who use a external process).
 -

Subject: [PATCH 27/27] [SERVER] Catch any error and return a 500 response
 instead of crashing.

The server will be running some code on the behalf of the calling code.
We really don't what to crash the library (and the binary) because
of a wrong request.
