189: write generated code to disk for easier inspection r=japaric a=japaric
now that the generated code is actually readable let's make it easier to access
this commit also documents how to inspect the generated code via
`rtfm-expansion.rs` and `cargo-expand`

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`.
170: check task priority at compile time r=TeXitoi a=japaric
before we were checking the priority at runtime. The compile time error message
when the priority is too high is kind of awful though.

This program was being accepted:
``` rust
#[task(
capacity = 1,
capacity = 2,
priority = 1,
priority = 2,
)]
fn foo() {}
```
now it will trigger a compiler error
closes#69
this doesn't change functionality per se but improves diagnostics in some cases. Some hard errors
have becomes warnings, for example: when `resources` is empty, or when `idle.path` is set to the
default `idle` path.
