core: Stabilize the mem module

Browse source 
Excluding the functions inherited from the cast module last week (with marked
stability levels), these functions received the following treatment.

* size_of - this method has become #[stable]
* nonzero_size_of/nonzero_size_of_val - these methods have been removed
* min_align_of - this method is now #[stable]
* pref_align_of - this method has been renamed without the
  `pref_` prefix, and it is the "default alignment" now. This decision is in line
  with what clang does (see url linked in comment on function). This function
  is now #[stable].
* init - renamed to zeroed and marked #[stable]
* uninit - marked #[stable]
* move_val_init - renamed to overwrite and marked #[stable]
* {from,to}_{be,le}{16,32,64} - all functions marked #[stable]
* swap/replace/drop - marked #[stable]
* size_of_val/min_align_of_val/align_of_val - these functions are marked
  #[unstable], but will continue to exist in some form. Concerns have been
  raised about their `_val` prefix.
