add lazy_load_hooks.rb, which allows us to declare code that
should be run at some later time. For instance, this allows
us to defer requiring ActiveRecord::Base at boot time purely
to apply configuration. Instead, we register a hook that should
apply configuration once ActiveRecord::Base is loaded.

With these changes, brings down total boot time of a
new app to 300ms in production and 400ms in dev.

fixed a 'RecordNotFound' bug when calling 'reload' on a object which doesn't met the default_scope conditions, added test [#3166 status:resolved]

The reload method didn't made use of 'with_exclusive_scope' when reloading the object. This lead to a RecordNotFound exception, in case the object doesn't met the default_scope condition (anymore) - which is obviously a bug. This quick fix makes use of with_exclusive_scope in the reload method as well. See test for full example.

Fix a bug where default_scope was overriding attributes given on model initialization [#3218 status:resolved]

Require persisted? in ActiveModel::Lint and remove new_record? and destroyed? methods. ActionPack does not care if the resource is new or if it was destroyed, it cares only if it's persisted somewhere or not.

Revert "Fixed: #without_typecast should only disable typecasting on the duplicated attributes" [#3387 state:open]

This reverts commit 28319964.

Reason :

  It's not generating attribute methods properly, making object.column 5x slower.
