This seems fine. I was a little concerned about whether it was okay to remove a feature gate like this without consulting the language team, but it seems that in all cases where an actual feature was/is being properly gated, it continues to be gated (by some other feature gate). @eddyb has pointed out that the |

Methods `Fn(Mut,Once)::call(mut,once)` are gated with two feature gates, remove one of them Methods `Fn::call`, `FnMut::call_mut` and `FnOnce::call_once` are gated with usual library feature `fn_traits` and also hardcoded in the compiler and gated once more with feature `unboxed_closures` This patch removes the `unboxed_closures`feature gate from these methods (`unboxed_closures` is still used for other things though), now they are gated only with `fn_traits`. All unnecessary `#![feature(unboxed_closures)]`s are removed, many of them are old and were already unnecessary before the change this PR does.
