The correct path for xapian database should be "X/fulltext/xapian",
not "Z//fulltextIndex/xapian".
So lets check for the right path and fallback to the wrong one (but
used in old zims).
The double '/' in the path is a bug of zimwriterfs and is specific
to the xapian database.
We must handle this correctly in `hasFulltextIndex` and not (buggly) in
`pathExists`.
(Hopefully, it seems that pathExists were used only by hasFulltextIndex)
The previous API suffer different problems:
- It was difficult to handle articles redirecting to other article.
- It was not possible to get few information (title) without getting
the whole content.
The new API introduce the new class `Entry` that act as a proxy to an
article in the zim file.
Methods of `Reader` now return an `Entry` and the user has to call
`Entry`'s methods to get useful information.
No redirection is made explicitly.
If an entry is not found, an exception is raised instead of returning
an invalid `Entry`.
The common pattern to get the content of an entry become :
```
std::string content;
try {
auto entry = reader.getEntryFromPath(path);
entry = entry.getFinalEntry();
content = entry.getContent();
} catch (NoEntry& e) {
...
}
```
Older methods are keep (with the same behavior) but are marked as
deprecated.
Add a `title` write argument to `getContent*` methods.
This argument is filled with the title of the content get.
Also update the JNI accordingly.

If a embedded fulltext database is present, suggestion will search in it :
- insensitive case search.
- search for terms in the middle of the title.
- xapian will try to complete the last word of the query (as if a '*'
were added at the end)
Compilation fails on clang 3.4.1 (and presumably later, tho I haven't tested) with
```

```
because we are not using the right type for the map iterator. As we are using
C++11, let's use `auto` and make compiler set the right type for us.
There is no more integrated build of dependencies in the build system.
Dependencies are discovered using pkg-config except for ctpp2 where there
is no pkg-config file.
