The warning is aiming at external use, not our own one. Silence the
latter by adding an internal service that the deprecated function calls
and use that service in the remaining mraa use cases.

This commit introduces mraa_gpio_init_by_name API for initializing
a GPIO by its line name provided by the kernel. This feature depends
on the GPIO chardev support and also the line names present in devicetree
or board files. Accessing GPIO using its line name, removes the dependency
from MRAA specific pin mapping and provides a cleaner way to access GPIOs.
This will solve the issue created by an external gpiochip probing before
the SoC's internal gpio controller and thereby making the MRAA pin mapping
wrong.
Currently, this API only supports initializing a single GPIO at a time.

Remove some _multiple functions and replace with generic function that
does both. Some general cleanup and will move more interrnal mraa
functions to use the _mraa prefix

Following changes are done as a part of cleanup:
1. Moved the platform specific `C` examples from top level examples/
directory to platform/ subdirectory and renamed helloedison.c to
gpio_edison.c
2. C specific examples are moved to a new c/ subdirectory. As a part
of this process, examples are modified to follow same standards
and few new examples are also added.
3. Include the newly added C examples to relevant API documentation
4. Ran clang-format for all source files in c/, c++/, platform/
subdirectories

This attribute is not part of gpio standard attributes
so it's necessary to implement a custom version of this function

Make use of 'active_low' interface in sysfs for configuring input pin
in pull up / pull down mode. C++ binding also has been added.

The reason for this is that applications that use mraa, like upm, need the
definitions contained in jni header.

libmraajava.so was statically linking to mraa object files causing
duplicate mraa platform instances if a UPM Java module was also loaded.
JNI functionality has been moved into src/java/mraajni.c. JVM object is
now set when JVM is loaded; see updates to src/java/mraajava.i.
This was necessary as the JVM object cannot be directly referenced from
mraa as it will not be available when building C/C++ examples.

There is an issue that when you take an IO pin that has an external PU
resistor and switch it from INPUT to OUTPUT the state of the pin will go
down before you can set it back high.
