Fix the drive logic for pullup and pulldown inputs.

Add a bitbanged I2C ACK checker for 0-byte I2C transfers (since the HW
doesn't support it).

Add a timeout on I2C reads and writes so they don't hang forever if a
device is not present.

Fixes #38

Add I2C slave support and include a simple example

Also fix the initial pins for the 2nd I2C interface onboard.

Add a CoreMutex class which implements a deadlock-safe mutex and reqork
the SerialUSB and SerialUART classes to use it to synchronize output
when in a multicore sketch.

Remove stdio hacks from libpico.a

Fixes #35

Fixes #34

Add a Gitter chat badge to README.md

Needed to fix link stage to pull in `%f` formatting support.

Fixes #32

Add project size to compile output.  Thanks to @vslinuxdotnet for the work!

Thanks to @vslinuxdotnet for digging into this!  Adds the compiled
sketch RAM and flash usage to the output.

Fixes #17

Set F_CPU macro, remove linker align warnings

Fix attachInterrupt to handle single GPIO callback

Fixes #23

The Pico SDK only supports a single callback pointer for all GPIO
interrupt pins.  So we need to track the individual pin-to-CB map
ourselves and dispatch from our own internal callback routine.

Fixes #25

Add attach/detachInterrupt support

Fixes #21

Use a constexpr template to calculate the valid pins for different IO
hardware.  This lets us have an easily readable list of pin numbers that
we can adjust/check.

Add serialEvent support for USB, UART0, UART1

Clean up gitignore, debug port configuation.  PicoProbe support began.

Add non-standard library calls used by String

Borrowed from https://github.com/esp8266/Arduino , include dtostrf() and
others.

Fixes #13

for the cases where one of the UARTs is used.

Thanks to @me-no-dev, the serial monitor issue was traced down to
DTR/RTS settings in boards.txt.  Clean those up and the monitor seems to
work perfectly now.

OpenOCD still needs to be added for this to work :)

Use chunks not bytes to transfer data to host, like in the serial_usb
SDK.

Add a symlink to the repo to point to the ArduinoAPI submodule instead
of requiring manual addition after athe first `git clone`.

Added size validation to the EEPROM begin, but forgot to set the class
variable with the new adjusted size.
Fixes #10
