471fdae993 nrf: Enable binascii, hashlib modules
These modules would be very handy to have in order to implement a
more robust replacement for ampy.  It costs around 2KiB of text and
no data or bss.

'binascii' has base64 encoding, which can be used to create a fully
8-bit-clean transport above the slightly cooked serial connection of
these boards.

'hashlib' is a bit less critical, but I have found it handy to
be able to robustly checksum remote files.

I see this as only being useful on ports which don't have USB block
device support, so atmel-samd doesn't need it.  These modules are
already on esp8266 so I think nrf52 seems like the only one that
needs it.

4adba51569 atmel-samd/samd21: Rework clock setup
Make clock setup explicit instead of using the convoluted asf4 macro setup.

enable_clock_generator():
- Add GCLK_GENCTRL_OE to stick with the current setup.
- Handle divisor larger than 31 for generator 2
- Change the source argument so it can take the GCLK_GENCTRL_SRC_XXXX_Val
  macros without casting to uint8_t.

This patch should not introduce any functional changes except keeping
GCLK_GENCTRL_OE enabled when the I2S clock is enabled.

ad1b16a3ec ports/esp8266: try both binascii and ubinascii in inisetup.py
in recent circuitpython builds, `ubinascii` is available as
`binascii`.  This modifies `modules/inisetup.py` to use the same
import semantics as `modules/websocket_helper.py`: first try importing
`ubinascii`, and if that fails, fall back to importing `binascii`.

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

right at the end of SRAM.

I verified by reading the source that the 4-byte-aligned address is
used for all samd21 / samd51 boards in
adafruit/circuitpython@efbf08266b.  However, I only tested on
trinket_m0.

37538fc0e7 Fix I2C init hang when the SCL pin is pulled low.
We added a check to make sure the pins are in a high state before
initing the bus. This leads to a friendly error message when someone
forgets to add the pull up resistors to their circuit.

where the top 4 bits of each byte were zero, because of
an incorrect bitmask used in this function.

a7e3c74fed Autocreate files that prevent MacOS indexing of the CIRCUITPYTHON dive
.. the price of this appears to be about 112 bytes of flash and 12
bytes of RAM, according to the stats printed during the build.

It also uses up 4 directory entries (out of 128), but does not reduce
the number of blocks usable for storing file contents.

These are the same items noted in the Adafruit README for Trinket M0
as preventing MacOS indexing.

Closes: #689

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)

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.

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.
