Instead of a furious storm of idle callbacks we just have one. This is a major performance gain - around 40% on my machine for the ping pong bench.
Also in this PR is a cleanup commit for the scheduler code. Was previously up as a separate PR, but bors load + imminent merge hell led me to roll them together. Was #8549.

Long-standing branch to remove foreign function wrappers altogether. Calls to C functions are done "in place" with no stack manipulation; the scheme relies entirely on the correct use of `#[fixed_stack_segment]` to guarantee adequate stack space. A linter is added to detect when `#[fixed_stack_segment]` annotations are missing. An `externfn!` macro is added to make it easier to declare foreign fns and wrappers in one go: this macro may need some refinement, though, for example it might be good to be able to declare a group of foreign fns. I leave that for future work (hopefully somebody else's work :) ).
Fixes #3678.

See discussion in #8489, but this selects option 3 by adding a `Default` trait to be implemented by various basic types.
Once this makes it into a snapshot I think it's about time to start overhauling all current use-cases of `fmt!` to move towards `ifmt!`. The goal is to replace `%X` with `{}` in 90% of situations, and this commit should enable that.

@brson grilled me about how this bugfix worked the first time around, and it occurred to me that it didn't in the case where the task is unwinding. Now it will.

Rename task::yield() to task::deschedule().
Fixes #8494.

Address issue #5257, for example these values all had the same hash value:
("aaa", "bbb", "ccc")
("aaab", "bb", "ccc")
("aaabbb", "", "ccc")
IterBytes for &[A] now includes the length, before calling iter_bytes on
each element.
IterBytes for &str is now terminated by a byte that does not appear in
UTF-8. This way only one more byte is processed when hashing strings.

|
Fixes #8359.

Add a testcase that verifies that (s, t) and (u, v) don't collide even if
s + t == u + v (concatenation).

I need `Clone` for `Tm` for my latest work on [rust-http](https://github.com/chris-morgan/rust-http) (static typing for headers, and headers like `Date` are a time), so here it is.
@huonw recommended deriving DeepClone while I was at it.
I also had to implement `DeepClone` for `~str` to get a derived implementation of `DeepClone` for `Tm`; I did `@str` while I was at it, for consistency.

(This doesn't add/remove `u`s or change `ize` to `ise`, or anything like that.)

updated, a minor amount of support type restructing has happened, methods have been reordered, and some duplicate code has been purged.

PausibleIdleCallback and placed the appropriate signatures in rtio and implementation into uvio.

from nondeterministic deadlock and also pending scheduler messages on scheduler shutdown.

By using a separate trait this is overridable on a per-type basis and makes room
for the possibility of even more arguments passed in for the future.

This allows the internal implementation details of the TLS keys to be
changed without requiring the update of all the users. (Or, applying
changes that *have* to be applied for the keys to work correctly, e.g.
forcing LLVM to not merge these constants.)

Implement interior null checking in `.to_c_str()`, among other changes.

Retry of PR #8471
Replace the remaining functions marked for issue #8228 with similar functions that are iterator-based.
Change `either::{lefts, rights}` to be iterator-filtering instead of returning a vector.
Replace `map_vec`, `map_vec2`, `iter_vec2` in std::result with three functions:
* `result::collect` gathers `Iterator<Result<V, U>>` to `Result<~[V], U>`
* `result::fold` folds `Iterator<Result<T, E>>` to `Result<V, E>`
* `result::fold_` folds `Iterator<Result<T, E>>` to `Result<(), E>`

These are obsoleted by the generic iterator `zip` adaptor. Unlike
these, it does not clone the elements or allocate a new vector by
default.

replaced by iterators (generic composable `map` and `zip` adaptors)
