284: book, Russian lang: fix "idle not defined" typo r=burbull a=kolen

Fix typo in Russian translation of book, was "When idle function is declared", should be "When no idle function is declared"

"не" means "not".

Corresponding text in English:

```markdown
When no `idle` function is declared, the runtime sets the [SLEEPONEXIT] bit and
then sends the microcontroller to sleep after running `init`.
```

283: Include DWT enable in migration guide r=korken89 a=MabezDev

Makes note of the fact the DWT has to be enabled manually in rtfm 0.5.0; an easy one to miss considering debuggers generally enable the DWT automatically.

277: TimerQueue.dequeue: don't set SYST reload to 0 r=korken89 a=mpasternacki

ARM Architecture Reference Manual says: "Setting SYST_RVR to zero has the effect of disabling the SysTick counter independently of the counter enable bit."

If Monotonic's ratio is less than one, the timeout calculations
can compute zero if next task is scheduled after current instant, but
before next timer tick. This results in disabling SYST and freezing the
timer queue.

The division by ratio's denominator rounds downward and the dequeue
condition is `if instant < now`. If ratio is small enough, this results
in unnecessary interrupts:

Let's say `instant - now` is 99 and ratio is 1/25. Then, `dur` will
equal 3 and the next tick will happen at `now + 75`. In the next
interrupt, `instant > now` and additional tick needs to be scheduled
(which doesn't happen, because now `instant - now` is less than 25, so
reload will be set to 0 and timer queue will stop). Adding one to
computed duration will prevent both freezing and additional interrupts.

When ratio is 1 or close, timer queue code overhead will prevent this
from happening. I am working with a chip where CPU is clocked at 600MHz
and SysTick is 100kHz and the freeze happens quite often.

278: Cyccnt r=texitoi a=perlindgren

The subtractions in `elapsed` and `duration` may cause an overflow panic in debug mode. This is solved by using wrapping arithmetics.

268: CI: replace compiletest-rs with trybuild r=japaric a=japaric

We use compiletest to run compile-fail tests but compiletest depends on compiler
internals so it breaks every now and then and requires nightly. With trybuild we
can also run compile-fail tests but it works on stable and it already has
reached version 1.0
