Marc-Antoine Ruel d0a4be1156 travis: enable more of go vet shadow check
Now running:
  ! go vet -vettool=$(which shadow) ./... |& grep -v '"err"' | grep -e '^[^#]'

Which means that "err" aliasing is not checked, but others are. I may
enforce "err" aliasing later but it's more noisy so I'm not 100% sure
yet it's a good idea. Enforcing it for non-err variables looked like a
reasonable initial trade-off.

        grep -v underscores | grep -v 'another file'

and fixed the comments that made sense.

Michael Traver ff89f66af2 mcp9808: Simplify bits to temperature conversions (#404)
- Converting the alert registers and the ambient temp register to a
  physic.Temperature can use the same procedure. Unify them and document
  why this is possible.
- Use != instead of > for bit checks
- Inline bitsToTemperature calls in SenseWithAlerts

Michael Traver e27c424b7b mcp9808: Fix conversions between temperature and bits (#403)
The datasheet (http://ww1.microchip.com/downloads/en/DeviceDoc/25095A.pdf)
says that negative temperatures are stored in two's complement. See
page 22 for alert registers and pages 24-25 for the ambient temperature
register.

However, the code currently assumes negative values are stored in a
sign-and-magnitude representation. Fix this to handle two's complement
values correctly.

For register bits to temperature conversion this implementation follows
the datasheet, but the code in the datasheet isn't quite right -- it
should be `temp - 256` instead of `256 - temp` -- but the fact that the
256 figure is in Microchip's code backs up the idea stated in the text
that negative values are in two's complement. Others seem to agree that
this is correct: https://electronics.stackexchange.com/a/244826

For temperature to bits conversion this implementation relies on the
fact that Go also uses two's complement. I've added a long comment in
the code about this.
