c80e3bac3e auto merge of #7244 : bblum/rust/once, r=nikomatsakis 
@graydon suggested that once closures not be part of the language for 1.0, but that they might be hidden behind a -Z compile flag as an "experimental feature" in case people decide they need them.

Regardless of whether ```-Z once-fns``` is set, this PR will parse the ```once``` keyword and will prevent closures labelled with it from being called more than once. It will also permit moving out of captured vars in heap closures, just to let the runtime writers stop using ```Cell``` sooner. Setting ```-Z once-fns``` only toggles whether the move-out-from-capture privilege is also given for stack closures.

closure is the last argument to the `new` method.

ee7307e6cb Smarter warning in extra::term::Terminal.reset() 
Don't spew a warn!() in reset() if num_colors is 0, because
non-color-supporting terminals are legit. Use debug!() there instead.
Continue spewing warn!() if we believe the terminal to support colors.

Use a better warning when the `op` capability can't be found.

d681bccb6a auto merge of #7471 : msullivan/rust/default-methods, r=graydon 
This fixes a bunch of default method bugs and restructures how vtable resolutions are represented.

(It also adds a depth counter to llvm::type_to_str as a hacky work around for our circular llvm types. This is related in the sense that I needed to do it to make debug tracing not cause rustc to crash after running out of stack space.)

0252693db2 Improve handling of trait bounds on a trait in default methods. 
This is work on #7460.
It does not properly handle certain cross crate situations,
because we don't properly export vtable resolution information.

e015bee286 Rewrite each_path to allow performance improvements in the future. 
Instead of determining paths from the path tag, we iterate through
modules' children recursively in the metadata. This will allow for
lazy external module resolution.
