b0e33f6a11 atmel-samd: UART: allocate rx buffer in long-lived region 
This is not strictly needed in order for #1056 to be resolved,
because the "make long-lived" machinery is unaware of this pointer.

However, as UARTs are assumed to be long-lived, this change is
beneficial because it moves the long-lived buffer into the upper
memory area with other long-lived objects, instead of remaining in
the low heap.

Move pin struct to the peripherals library. 
Its slimmed down by removing the qstr and bit packing TCC info.

The trinket m0 build actually grows by 20 bytes. The arduino zero
build shrinks by 188 bytes.

2fbab8067a Prevent freezing USB during high frequency PulseIn. 
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

28642ab10d Add audio output support! 
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263

dddfad6594 UART: Fix maybe-uninitialized diagnostic 
The following error occurs when building with gcc 5.4.1 (debian stretch):

common-hal/busio/UART.c:104:83: error: 'sercom_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]
                   sercom_insts[rx->sercom[j].index]->USART.CTRLA.bit.ENABLE == 0) ||

It may be related to the addition of rx-only UARTs; gcc is unable
to infer the intended relationship between have_tx and sercom_index
being set (I am still not entirely confident of it myself)

  c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST.
