88aa0e2660 Remove SERCOM pointers from pin data structure because index is 
enough.

This saves 380 bytes on the Arduino Zero build. (More pins ==
more savings.)

7a3f86d184 Check usb_busy up front in usb background function. 
Waiting to do so risks accidentally queueing another response.

Hopefully fixes #655 but we'll let @jerryneedell confirm.

c37ade9aeb Correct NO_TIMER index value for SAMD21. 
We check validity by ensuring it's lower than the total number of
timers. 0 is a terrible number for the NO_TIMER value because its
valid even though it shouldn't be.

Merge pull request #677 from tannewt/usb_active_read 
Move usb read finish into interrupt.

8157248189 Move usb read finish into interrupt. 
Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.

In that case, we'll read the appropriate data rather than write it
and never clear the active write.

Hopefully fixes #655.

9b4477e1dc Implement UART for 3.0 + related fixes. 
1. UART: ported to ASF4. Allow rx-only and tx-only. Add .baudrate r/w property.

2. Make NeoPixel timing deterministic by turning off caches during NeoPixel writes.
3. Incorporate asf4 updates:
  a. async USART driver
  b. bringing Atmel START configuration closer to what we use
  c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST.
4. supervisor/port.c: Move commented-out clock-test pin setting to correct location.

b001c0711b Correct _etext location; clean up .ld files 
1. Make _extext and _sidata coincide. Old _etext location did not include
.ARM.exidx sections, which were usually absent but not always. So flash
data was copied to RAM in wrong place.
2. Use decimal constants with "K" and "M" suffixes in .ld files instead
of hex constants, to make them easier to read and check for accuracy.

1. Turn off MICROPY_CPYTHON_COMPAT, which includes a number of minor CPython compatibility features,
most of which have workarounds, but uses up significant flash.
2. Turn on MICROPY_PY_SYS_MAXSIZE, which implements sys.maxsize.
3. Turn on MICROPY_CAN_OVERRIDE_BUILTINS, which implements "_" as the most recent value in the REPL,
and also enables redefining builtins.

  momentarily until a second transfer was attempted and a busy
  error was returned, therefore setting usb_busy to true. That
  risks the first "failed" transfer completing before a second one

On reads, the CSW is automatically sent when we reply with the
total length. Writes must do it manually so they can wait for the
disk to flush the data.
