SQL : grosse mise à jour avec mise en cache du nombre d'articles lus/non-lus

* Mise en cache du nombre d'articles lus et non-lus par flux, via
`f.cache_nbEntries, f.cache_nbUnreads` pour de biens meilleures
performances
* Implémente https://github.com/marienfressinaud/FreshRSS/issues/268
* Révision de la plupart des requêtes de modification en conséquence
* En cas d'affichage `not_read`, évite de faire une requête si on sait
déjà qu'il n'y a pas d'article non lu et fait directement un affichage
`all`.
* Appelle `cleanOldEntries` seulement une fois de temps en temps
aléatoirement (1 fois sur 30 actuellement) pour économiser les
ressources, et avant les insertions pour plus de robustesse.
* Utilisation des transactions lors de mises à jour multiples et liées
* Lors de requêtes de modifications, retourne le nombre de lignes
impactées plutôt qu'un booléen en cas de succès
* Suppression de code oublié relatif à is_public qui n'est plus utilisé
