Partly rollsback f2c4d95c15 which stopped
mraa_i2c_init from switching i2c bus silently. If you don't want this to
happen, you need to use mraa_i2c_init_raw. Closes#497.

This fixes previous broken commit because dev is not defined before
_internal_init but since fp is taken during internal init we need to know the
channel number. This does not affect the internal override API.

Using NPM, this module can be cross-compiled for Android using NDK.
But, when compiling for Android, we need to add glob.c to source files
(as in Android.mk).
Also, re-arranged the layout in binding.gyp for better readability.

This commit introduces support for Dallas Semiconductor (DS) 1-wire
compliant device support using an available UART device.
The principle of operation is described in the following Application
note by Maxim Electronics:
https://www.maximintegrated.com/en/app-notes/index.mvp/id/214
with help (1-wire search) from:
https://www.maximintegrated.com/en/app-notes/index.mvp/id/187
It has been tested on Galileo 2 and Edison, with 2 DS 1-wire devices,
the DS18B20 and DS2413 connected to the bus. A UPM driver for the
DS2413 is already complete and a PR will be submitted after this one.
It is important that you use a UART with CMOS/TTL level voltages
(3.3v/5v) RX and TX lines. DO NOT use standard RS232 level voltages
or you are going to have a bad day.
In order for this to work, a simple interface circuit, using a single
diode must be constructed:
(forgive my "Asciihematic" :)
-|
U|
A| TX---|<--+
R| |
T| RX-------o--------o 1-wire data bus
-|
The diode on TX is a 1N4148 (cheap and common), with the cathode
connected to TX, and the anode connected to RX and the 1-wire data
line.
The 1-wire data line requires a pull-up resistor, as the DS 1-wire
spec requires. 4.7-5K is typical for DS 1-wire buses.
NOTE: DHT-type (temp/humidity sensor) 1-wire devices ARE NOT DS 1-wire
compliant, and will not work with this code/circuit unfortunately.
Also note, this will use up one of your UARTs, which cannot be used
for any other purpose (ie: to access true UART-type serial devices).
You can however, connect as many DS 1-wire devices as feasible to this
UART, as it will function as a DS 1-wire bus master.

LIB_SUFFIX is no longer used. Replaced with LIB_INSTALL_DIR
which provides the correct lib dir with arch suffix.
Moved the call to include(GNUInstallDirs) prior to checking the
CMAKE_INSTALL_LIBDIR - which is set by include(GNUInstallDirs).
Tested with cmake 2.8 and cmake 3.5.

Currently, node modules install under the current environment's
node install path. This happens even if cmake is passed a
CMAKE_INSTALL_PREFIX.
This change checks if a CMAKE_INSTALL_PREFIX has been provided,
in which case it prepens the install path to the NODE_MODULE_INSTALL_PATH.
If a CMAKE_INSTALL_PREFIX has NOT been provided, the the mraa node
modules get install according to the NODE_ROOT_DIR.
This fixes a problem with an install case where the caller does not
have write access to the NODE_ROOT_DIR.

mraa_LIB_PLAT_SRCS_NOAUTO no longer used for firmata unlike USBPLAT but
mraa_LIB_SRCS_NOAUTO and this is now loaded before the standard src files for
mraa. The package still needs to be generated with IMRAA & FIRMATA enabled for
this to work.
