7041c014bb Added a MQTT pub/sub example of using AWS IoT (#173) 
* Added a MQTT pub/sub example of using AWS IoT (via ECC based TLS1.2 connection).

* Fixed a buffer overflow issue when receiving large MQTT packet.

* Reset TLS connection on read/write errors.

f0c43ff5d5 BME280 support. 
The BME280 is close to compatible with the existing BMP280 and extends it with support for measuring humidity, so support has been bundled into the bmp280 driver.

The example now auto-detects the device and displays the humidity for the BME280.

The I2C bus initialization has been moved out of the bmp280 driver to support multiple devices.

The check-id and reset logic has been bundled into the driver initialization. It needs to be re-initialized after reset anyway and the chip-id is need to initialize it, just re-initialize to reset.

Support has been added for multiple devices. The calibration data storage needs to be managed by the caller rather than static data. The caller can choose the I2C address to allow two BMx280 devices to be used on the same I2C bus.

An interface has been added to return the measurement values in an integer fixed float format. The float format interface is still there.

All the values are read in one I2C transaction to ensure they are a consistent set.

Renamed bmp280_calib_t to bmp280_t, and removed read_register8.

41d4427fba bmp180: separate the task and queue interface from the lower level support. 
This just separates them in the one file leaving it as possible future change to actually remove the higher level api or move it to an example.

05bbe48bd4 bmp180: make a lower level interface available and support oversampling. 
An application using multiple I2C devices will need it's own
loop. This reworks the code to make the detection, calibration
constant loading, and measurment functions available too without
having to use the bmp810 task which is still retained.

Adds support for oversampling.

Fixes a bug in the calculation of the temperature.

Better error handling. Checks for I2C errors and errors in the loading
of the calibration constants and propagates these up.

16157080cd i2c: use open drain outputs. 
Configure the pins as open-drain just in case the code forces them
high although it should be configuring them as inputs to let them float high.

Initialize the pins when the driver is initialized.

Enable the internal pull-ups to prevent them floating too high if not
connected and damaging the circuit.
