Merge pull request #17227 from claudiob/explicitly-abort-callbacks
Introduce explicit way of halting callback chains by throwing :abort. Deprecate current implicit behavior of halting callback chains by returning `false` in apps ported to Rails 5.0. Completely remove that behavior in brand new Rails 5.0 apps. Conflicts: railties/CHANGELOG.md

+* Change the way in which callback chains can be halted.
+
+ The preferred method to halt a callback chain from now on is to explicitly
+ `throw(:abort)`.
+ In the past, returning `false` in an ActiveRecord `before_` callback had the
+ side effect of halting the callback chain.
+ This is not recommended anymore and, depending on the value of the
+ `config.active_support.halt_callback_chains_on_return_false` option, will
+ either not work at all or display a deprecation warning.

* Clear query cache on rollback.
