auto merge of #19338 : nikomatsakis/rust/unboxed-closure-purge-the-proc, r=acrichto

They are replaced with unboxed closures.

cc @pcwalton @aturon 

This is a [breaking-change]. Mostly, uses of `proc()` simply need to be converted to `move||` (unboxed closures), but in some cases the adaptations required are more complex (particularly for library authors). A detailed write-up can be found here: http://smallcultfollowing.com/babysteps/blog/2014/11/26/purging-proc/

The commits are ordered to emphasize the more important changes, but are not truly standalone.
