std: stop `vec!()` warning about unused mutability.

If no arguments are given to `vec!` then no pushes are emitted and
so the compiler (rightly) complains that the mutability of `temp` is
never used.

This behaviour is rather annoying for users.
Explicitly write down 0.1 release date in RELEASES.txt, to confirm Rust's birthday.
change FVN hash function to the FVN-1a variant
auto merge of #12749 : tedhorst/rust/master, r=huonw

Minor change to the FVN hashing function based on recommendation on: http://en.wikipedia.org/wiki/Fowler_Noll_Vo_hash

rename ast::ViewItemExternMod to ast::ViewItemExternCrate, and clean::ExternMod to clean::ExternCrate
auto merge of #12750 : liigo/rust/De-extern-mod, r=alexcrichton

rename ast::ViewItemExternMod to ast::ViewItemExternCrate
rename rustdoc::clean::ExternMod to rustdoc::clean::ExternCrate
because `extern mod` is out.

Index cross-mod type definition and implementation properly in rustdoc

A structure's definition and implementation may be cross-module. If the
implementing module is parsed before defining module, the fully
qualified name of the structure won't be present for the implementation
to use when being indexed. So caches such 'orphan' implementation and
indexes it at the end of crate parsing.

Closes #10284.

create a sensible comparison trait hierarchy

* `Ord` inherits from `Eq`
* `TotalOrd` inherits from `TotalEq`
* `TotalOrd` inherits from `Ord`
* `TotalEq` inherits from `Eq`

This is a partial implementation of #12517.

doc: don't refer to 'char' as characters

This seems to be causing some confusion among users. Rust's char are
not 8bit characters, but 32bit UCS-4 codepoint without surrogates
(Unicode Scalar Values as per Unicode glossary).
Make the doc more explicit about it.
