More test fixes and fallout of stability changes

std: Split the `std_misc` feature

2015-06-17T16:06:59+00:00

Squeeze the last bits of `task`s in documentation in favor of `thread`

2015-05-08T17:24:18+00:00

An automated script was run against the `.rs` and `.md` files, subsituting every occurrence of `task` with `thread`. In the `.rs` files, only the texts in the comment blocks were affected.

Test fixes and rebase conflicts, round 2

2015-04-02T01:38:24+00:00

rollup merge of #23176: huonw/rm-bounds

2015-04-02T01:38:19+00:00

Added `T:Send` bound to `Queue` to avoid specialized Drop impl.

2015-03-24T21:27:23+00:00

Remove unneeded `Send` bounds from `std::sync::mpsc`.

2015-03-08T11:16:32+00:00

The requirements `T: Send` only matter if the channel crosses thread boundaries i.e. the `Sender` or `Reciever` are sent across thread boundaries, and which is adequately controlled by the impls of `Send` for them. If `T` doesn't satisfy the bounds, then the types cannot cross thread boundaries and so everything is still safe (the pair of types collectively behave like a `Rc>`, or something of that nature).

Add `: Box<_>` or `::Box<_>` type annotations to various places.

This is the kind of change that one is expected to need to make to accommodate overloaded-`box`. ---- Note that this is not *all* of the changes necessary to accommodate Issue 22181. It is merely the subset of those cases where there was already a let-binding in place that made it easy to add the necesasry type ascription. (For unnamed intermediate `Box` values, one must go down a different route; `Box::new` is the option that maximizes portability, but has potential inefficiency depending on whether the call is inlined.) ---- There is one place worth note, `run-pass/coerce-match.rs`, where I used an ugly form of `Box<_>` type ascription where I would have preferred to use `Box::new` to accommodate overloaded-`box`. I deliberately did not use `Box::new` here, because that is already done in coerce-match-calls.rs. ---- Precursor for overloaded-`box` and placement-`in`; see Issue 22181.

Use boxed functions instead of transmute

2015-02-22T23:59:17+00:00

... to convert between Box and raw pointers. E. g. use ``` let b: Box = Box::from_raw(p); ``` instead of ``` let b: Box = mem::transmute(p); ``` Patch also changes closure release code in `src/libstd/sys/unix/thread.rs` when `pthread_create` failed. Raw pointer was transmuted to box of `FnOnce()` instead of `Thunk`. This code was probably never executed, because `pthread_create` rarely fails in practice.
