This allows assigning platform pins to the CTS/RTS lines.
If provided, these will be muxed as UART when flow control is enabled.

The Pi doesn't have userspace level PWM support, but you can mmap the
raw registers and configure it that way, which is what this patch is
doing. Tested with Raspberry Pi 3 B. I am able to set the duty cycle,
change the frequency, and set the pulse width. Signals verified with
logic analyzer. Note that the only accessible pwm is on GPIO18, which is
also used by the audio subsystem.

Previously, mraa_iio_trigger_buffer took a void* args but did not use
this. Included implementation to allow user to pass a void* to this
method and have the corresponding pointer returned in the interrupt
handler.

There were unused variables, incorrect pointer operations
and plan broken string comparison.
Now there's only one - for unused uart3_enabled in beaglebone.c,
but we want to keep it for declaration consistency.
Also fixes#757.

Add gpio interrupt support for peripheral manager based on the
existing implementation in gpio.c.
Rewrite steps by using a global reference to lookup java isr
routine using JNI methods and add exception check after every call.
Free local reference class since it's not garbage collected and will
lead to a memory leak.

Be consistent with the return values from MRAA and propagate the
errors received from PIO in case of failure. PIO returns 0 on success
and negative errno on failure. Handle APIs that must return length of
read/written data if PIO returns success.

Beaglebone AIO pins seem to be a little different than most boards, so
this is my attempt to work with that without impacting other boards. I
added a new flag in mraa_board_t to indicate whether or not the aio pins
are sequential. One the beaglebone, they are not. To go along with this,
I added a new device mraa_aio_dev_t, that will map each aio to a
physical pin.
In the main aio logic, if aio_non_seq is true for the board, the manual
mapping is used, otherwise the old mathematical mapping is used.

Made the pin declarations a little nicer to look at. Found a bug with
the I2C. The higher layers were passing the bus ID itself, not the index
of the device in the i2c_bus array.

This patch adds a function to query UART settings in an unintrusive way.
It can be used using a uart index or a devpath and it strives to just
read out the settings without affecting the state of the UART.

This patch probably changes no functionality.
Before this patch the return value 0 was used for invalid baudrates in
uint2speed, but this is not a proper speed_t constant.
Instead the constant B0 is returned now, since on x86 and arm linux
architectures B0 is defined as 0.

This patch has no changes in function. It fixes three style issues
to be more readable and in line to the rest of the codebase:
- return types are declared on a separate line
- reversal of Yoda conditionals
- initialize for loop variable inside loop declaration
- Fix styling of pwm lookup doxygen
