The flag used for checking the kernel owned gpio line is GPIOLINE_FLAG_KERNEL.
Hence use that instead of GPIOLINE_FLAG_IS_OUT.
Flag used for checking the open source gpio line is GPIOLINE_FLAG_OPEN_SOURCE.
Hence use that instead of GPIOHANDLE_REQUEST_OPEN_SOURCE, which should be
only used when requesting lines.

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

This is a re-design of commit 0041801. mraa_lang_func_t structure has been
added (similar in design to mraa_adv_func_t) that points to JNI functions
implemented in src/java/mraajni.c. Functions are set by libmraajava.so,
see wrapper entry in src/java/mraajava.i. As gpio.c now uses these
functions, language specific #ifdef code has been removed as JNI code
is only called if functions are defined (i.e. not NULL)

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.

- FT4222 GPIO ISR implementation was specific to C/C++ and ignored
language binding support. This is now fixed via adv_func updates.
- GPIO ISR code has been refactored to reduce i2c traffic when using
I/O expanders
- Added support for built-in FT4222 GPIO interrupts

Add makefile for building libmraa library.
Import glob functionality from the NetBSD project where the glob.c and
glob.h files are released under BSD 3-clause License. Minor changes were
applied in order to make them compile for Android and Brillo.
This patch adds a control pipe used to interrupt the poll() function
as an alternative to pthread cancellation API.

Also modified ISR handler logic to account for the flag.
This fixes isrExit() deadlock in Python interactive mode
and prevents a more generic problem of a spurious ISR call
after mraa_gpio_isr_exit() is run.
