1. std: Second-pass stabilization of mem …

   This commit takes a second pass through the `std::mem` module for stabilization.
   The only remaining non-stable items in this module were `forget`, `transmute`,
   `copy_lifetime`, and `copy_lifetime_mut`.
   
   The `forget` and `transmute` intrinsics themselves were marked `#[stable]` to
   propgate into the `core::mem` module so they would be marked stable.
   
   The `copy_lifetime` functions were left `unstable`, but `Sized?` annotations
   were added to the parameters to allow more general use with DSTs.
   
   The `size_of_val`, `min_align_of_val`, and `align_of_val` functions would like
   to grow `Sized?` bounds, but this is a backwards compatible change that
   currently ICEs the compiler, so this change was not made at this time.
   
   Finally, the module itself was declared `#![stable]` in this pass.

2. std: Second pass stabilization of default …

   This commit performs a second pass stabilization of the `std::default` module.
   The module was already marked `#[stable]`, and the inheritance of `#[stable]`
   was removed since this attribute was applied. This commit adds the `#[stable]`
   attribute to the trait definition and one method name, along with all
   implementations found in the standard distribution.
