machine: make machine.I2C0 and similar objects pointers
...
This makes it possible to assign I2C objects (machine.I2C0,
machine.I2C1, etc.) without needing to take a pointer.
This is important especially in the future when I2C may be driven using
DMA and the machine.I2C type needs to store some state.

all: add compiler support for interrupts
...
This commit lets the compiler know about interrupts and allows
optimizations to be performed based on that: interrupts are eliminated
when they appear to be unused in a program. This is done with a new
pseudo-call (runtime/interrupt.New) that is treated specially by the
compiler.

machine/samd21: switch UART to use new pin configuration
...
This allows all possible UART pin configurations to be used and avoids
some tricky configuration.

machine/samd21: use pins specified in I2CConfig
...
Instead of configuring machine.I2C0, machine.I2C1, etc. statically,
allow the pins to be set using machine.I2CConfig. This will also
automatically configure the correct pin mode for each pin instead of
having to specify that manually.

machine/atsamd21: refactor SPI pin handling to only look at pin numbers
...
Pin mode and pad numbers are automatically calculated from the pin
numbers, returning an error if no pinout could be found.
