Added standard context validity check, another check for a replace function
and corrected a return statement to fit our standard code style.

Mock platform allows one to use mraa without having any real HW.
This commit makes necessary foundational changes and implements
GPIO functionality as well as adds respective tests.

As described in issue #91, on Edison setting 0% duty doesn't
disable the PWM on a pin completely.
Therefore we add a couple of Edison-specific _pre functions
and an internal PWM state variable, which we use to toggle PWM
enabled/disabled based on what duty is set for the pin.
Closes#91.

Add pin commands. Old mraa_setup_mux_mapped style is used for other boards
(pincmd = PINCMD_UNDEFINED) where pincmds are not defined.Remove useless
pullup_enable code, Galileo Gen2: review all pin mux and add commands Galileo
Gen2: remove doubled functionality: mraa_intel_galileo_gen2_i2c_init_pre and
mraa_intel_galileo_gen2_uart_init_pre. Galileo Gen2: fix "Invalid AIO pin
specified - do you have an ADC?" error. Galileo Gen2: pullup/pulldown
resistors are disabled during UART/GPIO/SPI/I2C/UIO initialization. Use
mraa_gpio_mode to enable resistors.

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

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.

Every 96Boards baseboard uses the same expansion connector, but the
current 96Boards initialization code assigns the SoC specific GPIO
numbers instead of being consistent across all boards. Change the code
to assign 96Boards GPIO-A through GPIO-L to MRAA GPIOs 23-34.
v2: Create info for all the LS connector pins, not just the GPIO pins.
This gives us room to describe other pins in the future.

* GPIO (via sysfs)
* UART
* I2C
* SPI
* PWM

- 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

The pinout for the Low Speed Expansion on the MinnowBoard
Turbot is the same as the MinnowBoard MAX A2 desgin, with
the exception of pin 26. Pin 26 was changed to provide an MCLK
reference clock for I2S.
In addition, the D2 LED is now under GPIO control.
Add support for these changes.
