This is the initial version of using nuspell for spelling correction,
which yet has to be tuned.
Note that libnuspell must be available as a dependency.
Xapian-based code for spelling correction is not deleted.
The path parameter of the SpellingsDB constructor has been changed to
denote the path of the cache directory where spellings databases for
different ZIM archive should be stored. The filename of the spellings
database is generated from the ZIM archive UUID and the current version
of the spellings database implementation.
- Restored kiwix::getNetworkInterfaces() API to the version before
support for IPv6 was introduced
- Renamed the new API method to kiwix::getNetworkInterfacesIPv4Or6()
`MigrationMode` was kind of defined in the context of an internal mode
used by `migrateBookmark(...)`.
But now, with `getBestTargetBookId`, it is broken.
This commit fix that and the associated implementation.
Now `UPGRADE_ONLY` will make `getBestTargetBookId` return only newer books.
and `ALLOW_DOWNGRADE` will return older books only if current book is
invalid.
Now the search results page is presented by the backend in the language
controlled by the value of the `userlang` URL query parameter (or, if
the latter is missing, the value of the `Accept-Language:` HTTP header).
Note that the front-end doesn't yet take advantage of this
functionality.
By moving the nameMapper/library arguments in `getHtml`/`getXml` we avoid
any potential "use after free" of name mapper or library as they are not
stored.
As we now always use Library through a shared_ptr, we can make `Library`
not copiable and not movable.
So we can move back the data in `Library`, we don't care about move
constructor.
The why of this mutex is in `Library` is a bit complex.
It has been introduced in c2927ce when there was only `Library` and no
`std::unique_ptr<Impl>`.
As introducing the mutex imply implementing the move constructor, we have
split all data in `LibraryBase` (and keep a default move constructor here)
and add the mutex in `Library` (and implement a simple move constructor).
Later, in 090c2fd, we have move the `LibraryBase` to `Library::Impl`
(which should have been `Library::Data`).
So at the end, `Library::Impl` is never moved. We can move the `mutex` in
it and still simply implement move constructor for `Library`.
We want to be sure that `Library` actually exists when we use it.
While it is not a silver bullet (user can still create a shared_ptr on
a raw pointer), making the `Server` keep `shared_ptr` on the library
help us a lot here.

Created a generic function multipleQuery which takes:
1. string (representing a comma separated list)
2. param (the value to query on using Xapian).
Category and language query will use this function.
