0b5afce771 refactor Resource / Threshold into its own crate, drop task!, tweak rtfm::atomic
task! can be re-added in a backward compatible fashion and I'd like to not have
two ways to assign a task handler to an interrupt / exception in the first
release.

rtfm::atomic now uses the `Threshold` token instead of the `CriticalSection`
token. This reduces overhead by dropping the "are interrupts enabled?" check.

3cebf49a2f syntax tweaks, relax check, add set_pending(), deal with imported types
- allow trailing commas in list of resources

- make task.resources optional

- add rtfm::set_pending function which can be used to force an interrupt into
  the pending state. This is a replacement of the old rtfm::request.
  rtfm::set_pending takes the Interrupt enum provided by the device crate as
  argument. (The old rtfm::request took a task function as argument)

- the user may want to use types they imported into the root of the crate. These
  types are not available in e.g. `mod idle` so `idle::Resources` *can't* be
  defined in that module. To workaround this problem `idle::Resources` will be
  defined in the root, with some other name, and then be re-exported in the
  `idle` module.

- remove the "a resource only used by one task should be local data" check. In
  some cases you do want a resource owned by a single task instead of local
  data since `init` can access resources but not a task local data.

759ac160db remove the borrow_mut method from resources
it can be used to break references rules within nested locks

``` rust
static R1: Resource<bool, C1> = unsafe { Resource::new(false) };
static R2: Resource<bool, C2> = unsafe { Resource::new(false) };
static R3: Resource<bool, C3> = unsafe { Resource::new(false) };

// Priority = 1
extern "C" fn j1(task: interrupt::Exti0Irq) {
    R1.lock(&task, |r1, c1| {
        R2.lock(&task, |r2, c2| {
            R3.lock(&task, |r3, mut c3| {
                // BAD &- and &mut - that point to the same data
                let r1_ref: &bool = R1.borrow(&c2);
                let r1_ref_mut: &mut bool = R1.borrow_mut(&mut c3);
            });
