Android need to handle the redirection by doing a redirection in the web
view, not by providing the content of the targeted article.
This is already what we do in kiwix-serve or ios.
The API should be far better by returning a Entry but for now,
we just change the given url if the article is a redirection.
If the `nativeHandle` is null, the JNIKiwixReader is invalid and we must
not use it.
Throwing an exception for the caller code to handle this properly.
And previously, user code has no way to detect something went wrong :/
For binary content (not compressed), it could be interesting to
directly read the content in the zim file instead of using `kiwix-lib`.
This method returns the needed information to do so (if possible).
Add the jni method `getContentPart` to get only a part of the artcicle
content.
The method can be used to get a part of the content or to know the size
of the full content.
This is a major API break. User code will have to be rewritten.
Before this commit, API was a unique object wrapping the library and
handle a global state with one `Reader` and one `Writer` at the time.
Now, the API is axed around three main objects :
- The `JNIKiwixReader`, a wrapper around a `kiwix::Reader` (who allow to
read one zim)
- The `JNIKiwixSearcher`, a wrapper around a `kiwix::Searcher` (who allow
to search through one or more reader(s))
- The `JNIKiwixSearcher.Result` a result of a search. Allowing to get all
information about a result (title, url, content, snippet, ...)
