M-A 441dfbc2a4 physic: Improve Frequency rounding, add Period() (#386) 
- Improve rounding and add unit tests to confirm.
- Period() is the same function than Duration() but better describes what
  is returned.
- Fix support for negative value.
- Upgrade all call sites inside periph.
- Fix Frequency documentation that incorrectly stated it's an int32,
  it's in fact an int64.
- Duration() will be removed in v4.0.0 as part of issue #379.

Marc-Antoine Ruel f325631d2a Bring back compatibility with go1.4.2 
- apa102 benchmark used image.CMYK, which was added in go 1.5. This has the side
  effect of making benchmark BenchmarkDrawSlowpath a bit faster.
- mpu9250 used type aliasing by accident, which was added in go1.9.
- periph-web used http.Server.Shutdown(), which was added in go1.8.

Marc-Antoine Ruel 6e81933d56 Start standardizing function names 
This is important to enable portability across platforms.

- UART_TX, UART_RX, UART_RTS, UART_CTS
- SPI_MISO, SPI_MOSI, SPI_CLK

This could break users who were depending on the previous wording but that would
be highly surprising.
