Support printf formats in terminfo strings

terminfo parameterized strings supports a limited subset of printf-style
formatting operations, such as %#5.3d.
Cleanup src/librustc/back
syntax::diagnostics: Color the ^~~~ in green for better visibility

Fixes #7164.
extra: Add a testcase for #7256.
Avoid unnecessary scratch datums for by-copy function arguments

Currently, by-copy function arguments are always stored into a scratch
datum, which serves two purposes.  First, it is required to be able to
have a temporary cleanup, in case that the call fails before the callee
actually takes ownership of the value. Second, if the argument is to be
passed by reference, the copy is required, so that the function doesn't
get a reference to the original value.

But in case that the datum does not need a drop glue call and it is
passed by value, there's no need to perform the extra copy.
Get cross crate default methods working.

This fixes the large number of problems that prevented cross crate
methods from ever working. It also fixes a couple lingering bugs with
polymorphic default methods and cleans up some of the code paths.

Closes #4102. Closes #4103.
librustc: Don't allow enum struct variants to shadow structs.
Add test for duplicate definitions of structs and enum struct variants.
auto merge of #7161 : kballard/rust/terminfo-parm-format, r=thestinger

Introduce support for terminfo's subset of printf-style formatting on doxXs operations.

More 0.7 release notes
Show defaults in rustdoc usage message
fix text of tutorials
Update AUTHORS.txt
Minor doc updates to reflect #[deriving(Zero)], and small release notes adjustments.

The `extra::fileinput` module landed just after 0.6 was released, and there are many
more derivable traits.
Usable instructions for generating docs from source
auto merge of #7203 : msullivan/rust/default-methods, r=graydon

This fixes the large number of problems that prevented cross crate
methods from ever working. It also fixes a couple lingering bugs with
polymorphic default methods and cleans up some of the code paths.

Closes #4102. Closes #4103.

vec: remove each_const

An Iterator implementation can be made for &const [T] if it turns out
to be necessary for some use case.
vec: remove eachi

replaced by the `enumerate` method from std::iterator
vec: rm old_iter implementations, except BaseIter

The removed test for issue #2611 is well covered by the `std::iterator`
module itself.

This adds the `count` method to `IteratorUtil` to replace `EqIter`.
