As we still create a `Reader` in the deprecated code of `Library`,
we need a way to create a reader without raising a deprecated warning.
So we create a another constructor with a dummy argument and we use it.
Each sugestions used to be stored as vector of strings to hold various values
such as title, path etc inside them. With this commit, we use the new
dedicated class `SuggestionItem` to do the same.
Previous API were using an internal vector to store the suggestions search
results.
The new API takes a vector as out argument. So user can call the functions
without having to protect the search.
We should change the android API to reflect the change but it is a bit
more complex to do at JNI level. As android do not call it multithreaded
we are safe for now. And we need the new API asap for kiwix-desktop.
So we keep the same API on android for now, the new api will be made
in next version.
The `common` name is from the time where kiwix was only one repository
for all the project (android, desktop, server...).
Now we have split the repositories and kiwix-lib is the "common" repo,
the "common" directory is somehow nonsense.
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.
