Merge #124

124: use panic-halt instead of panic-{abort,semihosting} r=therealprof a=japaric

the former requires a feature gate; the later pulls in the cortex-m crate

Eventually we want to test this crate on beta. To do that our dependencies must
not contain feature gates. That's not the case of `panic-abort`, which depends
on the `core_intrinsics` feature.

This PR fixes that. I could have used `panic-semihosting` everywhere but decided
for `panic-halt` which has zero dependencies as I figured that might slightly
decrease CI times.
