This mainly use the "new memory system". No need to call dispose function.
Rename the class to Library to conform with the naming semantics
(JNIKiwix* use old memory system)
The JNIKiwixManager is used to manage (insertion of book in) the library.
It is created, as needed, using an existing Library as input.
It is then used to add books, parse library.xml or opds content.
Then it can be destruct (and must be) with the `dispose` method.
```java
library = JNILibrary(...);
manager = JNIManager(library);
manager.parseOpds(opdscontent);
manager.dispose();
// library contains the books declared in the opds content.
// Use the library methods to get the books' info.
```
As we use the main library of gtest (if already installed)
we don't need to (and must not) define a main function for the tests.
Does the same (use main library) if we use the subproject.
All path must be utf8. This is already the case in all our project.
(If this not the case, this is a bug)
So we don't need to have a version with a native and utf8 path.
For some reason, `homebrew install gcovr` now install python3 as
dependency.
This is a dependency since a long time, I don't know why it was not
installing it before.
But the installation fails because it cannot link correctly python3
because python2 is already installed.
Then meson, when it tries to run the conversion script, fails because
the script cannot find python3.
The solution I've found is to unlink python2 and relink python3 to have
a correct installation of python3.
Set the different filter's fields only when we are requested to filter
them. Else, we ends to requests that some fields are empty.
If the request has no argument, we raise an exception (catched) and so
we don't set the corresponding field in the filter.
Fix#303
The default value of this parameter is false, in this case all the bookmarks
are returned, otherwise only those who are related to books of the library.
