`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.
`false` is a pretty bad default value as most user want to track
the real download.
By removing the default value, we force user to make a choice.
We could have change the default value to true but it would have been
a silent API change and we don't want that.
From now on, the `lang` parameter of the /catalog/search,
/catalog/v2/entries, and /catalog/v2/partial_entries endpoints is
interpreted as a comma-separated list of languages.
