 - Added an associative error type to [`AllocRef`]. Besides adding the possibility of returning additional information on
   allocation failure, it's also possible to split the usage of the [`AllocRef`] into a fallible and an infallible case.
-  Personally I think this is a pretty big deal, as kernel programmer can rely on allocation, which will never fail. If
-  an allocation can fail, only a `try_*_in` method may be available. To maintain backwards compatibility, [`AbortAlloc`]
-  was introduced. [`AbortAlloc`] wraps another allocator, but aborts on OOM thus `AbortAlloc<Global>` may be used as
-  default allocator for [`Box`] or `Vec`. To realize this, [`AbortAlloc`] implements `AllocRef<Error=!>`.
