194: bump heapless dependency to v0.5.0; remove "nightly" feature r=japaric a=japaric
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

193: remove unused check r=japaric a=japaric
that was added in #140 but it's no longer required
this PR also adds some cfail tests to test the updated code

192: removes the maybe_uninit feature gate r=japaric a=japaric
and stop newtyping `core::mem::MaybeUninit`
this also fixes CI on nightly

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`

191: generate resource proxies only when needed r=japaric a=japaric
only `static mut` resources need proxies
just a codegen optimization

176: implement RFCs 147 and 155, fix#141, etc. r=japaric a=japaric
This PR:
- 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 (see PR #175).
- 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 (TODO backport this into the v0.4.x branch).
- Shrinks the size of all the internal queues by turning `AtomicUsize` indices
into `AtomicU8`s.
- Removes the integration with `owned_singleton`.

Additionally:
- This changes CI to push v0.5.x docs to
https://japaric.github.io/rtfm5/book/en/ -- we need to do this because our
official docs are hosted on https://japaric.github.io/cortex-m-rtfm and we
need to keep them on v0.4.x until we release v0.5.0
- I propose that we use the master branch to develop the upcoming v0.5.0.
- I have created a branch v0.4.x for backports; new v0.4.x releases will come
from that branch.
r? @korken89 @texitoi, sorry for doing all the impl work in a single commit --
I know that makes things harder to review for you.
Suggestions for compile-pass and compile-fail tests are welcome

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.
