This PR was merged into the master branch.Discussion----------Updates to DI config for 3.3Hi guys!WIP changes the new DI changes in 3.3! Woohoo! Some notes for myself:This relates to, oh, just these 10+ issues :). Assume they will all be closed by this one PR - before merge, if any of them aren't covered, I'll remove them.TODOS later (some might already be done)- update to use `debug:container --types` (symfony/symfony#22624)- update all other documents for possible changes for autowiring and autoconfigure- new page for existing Symfony users to explain the changes- update autowire section to talk about using aliases- document instanceof and also the ability to add configuration to the PSR4 loader- some links in the controller go to the API docs of `Controller`. But this is wrong, the methodsnow live in `ControllerTrait`... but the API docs for traits is basically broken:http://api.symfony.com/master/Symfony/Bundle/FrameworkBundle/Controller/ControllerTrait.html- how should we pass a parameter to a controller?- do Twig extensions still need to be public? If so, the example in `service_container` about autoconfigure is still not quite rightDefinitely included in this PR*#7544*#7482*#7339*#7672Not included in this PR (but related to DI changes)*#7329*#7782*#7777*#7706*#7608*#7538*#7441*#7255* ~~#7041~~* ~~#7445~~* ~~#7444~~* ~~#7436~~Commits-------22adfbd removing duplicate target12c4944 Tweaks after amazing review from@GuilhemN and@xabbuhcac3c6c Merge remote-tracking branch 'origin/master' into di-3.3-changes2229fd3 Merge remote-tracking branch 'origin/master' into di-3.3-changes5452c61 Adding section about public: falseee27765 Adding versionaddedbc7088d Merge remote-tracking branch 'origin/di-3.3-changes' into di-3.3-changes443aec2 Merge pull request#7857 from GuilhemN/patch-189e12de bad link6de83e2 fixing build problem759e9b2 last tweaks from feedback45500b3 Adding details and usages of fetching the service as a controller arg70178d1 adding note about autoconfigure6e6ed94 more tweaks0e48bd8 [WIP] Updates to DI config for 3.39ab27f0 Add xml files2636bea bad linkc45daf4 fixing build problem9e84572 last tweaks from feedback049df7d Adding details and usages of fetching the service as a controller arg105801c adding note about autoconfigure2d11347 more tweaks8433fc1 [WIP] Updates to DI config for 3.3
