auto merge of #13053 : alexcrichton/rust/removing-ref-cell-get, r=huonw

This commit removes the `get()` method from `Ref` and `RefMut` in favor of the `*` operator, and removes all usage of the `deref()` function manually from rustc, favoring using `*` instead.

Some of the code is a little wacky, but that's due to either #13044 or #13042
Add Vec::mut_slice_from(), mut_slice_to(), and mut_split_at()
auto merge of #12995 : Kroisse/rust/vec_ng_mut_slices, r=alexcrichton

These functions are implemented for &mut [T], but std::vec_ng::Vec has not yet.
Get rid of @Cell
Unindent stringifier() in tasks guide
auto merge of #13076 : FlaPer87/rust/remove-freeze, r=alexcrichton

This PR removes the `Freeze` kind and the `NoFreeze` marker completely.

Fixes #12577

cc @nikomatsakis r?
auto merge of #13084 : Havvy/rust/master, r=alexcrichton

The indentation looks off in the guide because the main() function is not shown, so I'm dedenting the visible function.
Implement vtable support for autoderef.
Closes #13042.
auto merge of #13085 : edwardw/rust/saddest-cell, r=cmr
Implement cross-crate support for autoderef.
Closes #13044.
auto merge of #13087 : eddyb/rust/fix-autoderef, r=cmr

Implements vtable support for generic Deref impls with trait bounds.
Also fixes cross-crate inlining when using autoderef.
Some cleanup in std::io::buffered

`Vec` is now used for the internal buffer instead of `~[]`. Some module
level documentation somehow ended up attached to `BufferedReader` so I
fixed that as well.
Change types T,U to R (recv), S (sender) in libsync/comm.rs
make std::managed private

This removes two tests built on `managed::refcount`, but these issues
are well-covered elsewhere for non-managed types.
auto merge of #13089 : thestinger/rust/managed, r=Aatch

This removes two tests built on `managed::refcount`, but these issues
are well-covered elsewhere for non-managed types.
use TotalEq for HashMap

Closes #5283
auto merge of #13088 : thestinger/rust/hashmap, r=cmr

Closes #5283
iter: remove `to_owned_vec`

This needs to be removed as part of removing `~[T]`. Partial type hints
are now allowed, and will remove the need to add a version of this
method for `Vec<T>`. For now, this involves a few workarounds for
partial type hints not completely working.
auto merge of #13090 : thestinger/rust/iter, r=Aatch

This has been rendered obsolete by partial type hints. Since the `~[T]`
type is in the process of being removed, it needs to go away.
