30d6327001 bump heapless dependency to v0.5.0; remove "nightly" feature 
with the upcoming version of heapless we are able to initialize all internal
queues in const context removing the need for late initialization

this commit also removes the "nightly" feature because all the optimization
provided by it are now enabled by default

a452700628 implement RFCs 147 and 155, etc. 
This commit:

- Implements RFC 147: "all functions must be safe"

- Implements RFC 155: "explicit Context parameter"

- Implements the pending breaking change #141: reject assign syntax in `init`
  (which was used to initialize late resources)

- Refactors code generation to make it more readable -- there are no more random
  identifiers in the output -- and align it with the book description of RTFM
  internals.

- Makes the framework hard depend on `core::mem::MaybeUninit` and thus will
  require nightly until that API is stabilized.

- Fixes a ceiling analysis bug where the priority of the system timer was not
  considered in the analysis.

- Shrinks the size of all the internal queues by turning `AtomicUsize` indices
  into `AtomicU8`s.

- Removes the integration with `owned_singleton`.

6b61cd2e3f Merge #153 
153: add "nightly" feature; replace hint::unreachable_unchecked with a panic r=korken89 a=japaric

this implements the action plan described in #149

to give you a sense of the overhead of this change: it has increased the binary
size of some of our examples by up to 10% but this is mainly from pulling in a
panic handler that does formatting

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.
