bba701c59d std: Drop Total from Total{Eq,Ord}
This completes the last stage of the renaming of the comparison hierarchy of
traits. This change renames TotalEq to Eq and TotalOrd to Ord.

In the future the new Eq/Ord will be filled out with their appropriate methods,
but for now this change is purely a renaming change.

748bc3ca49 std: Rename {Eq,Ord} to Partial{Eq,Ord}
This is part of the ongoing renaming of the equality traits. See #12517 for more
details. All code using Eq/Ord will temporarily need to move to Partial{Eq,Ord}
or the Total{Eq,Ord} traits. The Total traits will soon be renamed to {Eq,Ord}.

6efd16629c rustc: Add official support for weak failure
This commit is part of the ongoing libstd facade efforts (cc #13851). The
compiler now recognizes some language items as "extern { fn foo(...); }" and
will automatically perform the following actions:

1. The foreign function has a pre-defined name.
2. The crate and downstream crates can only be built as rlibs until a crate
   defines the lang item itself.
3. The actual lang item has a pre-defined name.

This is essentially nicer compiler support for the hokey
core-depends-on-std-failure scheme today, but it is implemented the same way.
The details are a little more hidden under the covers.

In addition to failure, this commit promotes the eh_personality and
rust_stack_exhausted functions to official lang items. The compiler can generate
calls to these functions, causing linkage errors if they are left undefined. The
checking for these items is not as precise as it could be. Crates compiling with
`-Z no-landing-pads` will not need the eh_personality lang item, and crates
compiling with no split stacks won't need the stack exhausted lang item. For
ease, however, these items are checked for presence in all final outputs of the
compiler.

It is quite easy to define dummy versions of the functions necessary:

    #[lang = "stack_exhausted"]
    extern fn stack_exhausted() { /* ... */ }

    #[lang = "eh_personality"]
    extern fn eh_personality() { /* ... */ }

cc #11922, rust_stack_exhausted is now a lang item
cc #13851, libcollections is blocked on eh_personality becoming weak

81ec1f3c18 Rename Pod into Copy
Summary:
So far, we've used the term POD "Plain Old Data" to refer to types that
can be safely copied. However, this term is not consistent with the
other built-in bounds that use verbs instead. This patch renames the Pod
kind into Copy.

8e285208d5 auto merge of #12686 : FlaPer87/rust/shared, r=nikomatsakis
`Share` implies that all *reachable* content is *threadsafe*.

Threadsafe is defined as "exposing no operation that permits a data race if multiple threads have access to a &T pointer simultaneously". (NB: the type system should guarantee that if you have access to memory via a &T pointer, the only other way to gain access to that memory is through another &T pointer)...

Fixes #11781
cc #12577 

What this PR will do
================

- [x] Add Share kind and
- [x]  Replace usages of Freeze with Share in bounds.
- [x] Add Unsafe<T> #12577
- [x] Forbid taking the address of a immutable static item with `Unsafe<T>` interior

What's left to do in a separate PR (after the snapshot)?
===========================================

- Remove `Freeze` completely

2a14e084cf Move std::{trie, hashmap} to libcollections
These two containers are indeed collections, so their place is in
libcollections, not in libstd. There will always be a hash map as part of the
standard distribution of Rust, but by moving it out of the standard library it
makes libstd that much more portable to more platforms and environments.

This conveniently also removes the stuttering of 'std::hashmap::HashMap',
although 'collections::HashMap' is only one character shorter.

968633b60a Replace crate usage with krate
This patch replaces all `crate` usage with `krate` before introducing the
new keyword. This ensures that after introducing the keyword, there
won't be any compilation errors.

krate might not be the most expressive substitution for crate but it's a
very close abbreviation for it. `module` was already used in several
places already.

201cab84e8 Move rust's uv implementation to its own crate
There are a few reasons that this is a desirable move to take:

1. Proof of concept that a third party event loop is possible
2. Clear separation of responsibility between rt::io and the uv-backend
3. Enforce in the future that the event loop is "pluggable" and replacable

Here's a quick summary of the points of this pull request which make this
possible:

* Two new lang items were introduced: event_loop, and event_loop_factory.
  The idea of a "factory" is to define a function which can be called with no
  arguments and will return the new event loop as a trait object. This factory
  is emitted to the crate map when building an executable. The factory doesn't
  have to exist, and when it doesn't then an empty slot is in the crate map and
  a basic event loop with no I/O support is provided to the runtime.

* When building an executable, then the rustuv crate will be linked by default
  (providing a default implementation of the event loop) via a similar method to
  injecting a dependency on libstd. This is currently the only location where
  the rustuv crate is ever linked.

* There is a new #[no_uv] attribute (implied by #[no_std]) which denies
  implicitly linking to rustuv by default
