This commit changes the mraa_i2c_read() API call behaviour, a register should
now always be set when using this call. The smbus helper library is no longer
required since the code is now all contained from i2c.c which avoids multiple
function calls

Transfer command works with a uint8_t buffer that is written into, this does
not work in SWIG APIs and will cause a copy in either case, so the API call is
not useful. Remove to stop confusion.

Added minimum, maximum and default period settings to board definitions
PWM will now have a default period as defined in the board defintion.
When using pwm_write() writing 1.0f or above will default to 100%.

Header only C++ function definitions need to be static to avoid linking issues
when including the header multiple times.

When using SPI, I prefer to not have to do malloc/free functions for each
transfer, so why not have a transfer function that you can pass in both
buffers. With my ILI9341 TFT display code that gave some perf wins, also more
of a win, you can pass in NULL for recv buffer and the underlying device driver
does not have to copy the data.

* Exceptions only fired in constructor when it would initialise with a NULL
context causing segfaults if used any further
* Adds exception.i requirement to mraa.i for node.js and python support

Syslog is now used for all error messages, return values in the code should be
used by programmers to see the status of the library/board and syslog can be
used to see quickly from a debugging perspective what has gone wrong. A few
cosmetics where improved as well as a mraa_set_log_level() call where the
syslog log mask can be set directly from libmraa.

Functions inside namespace are tough to document, bypassing this by documenting
the namespace and then using the namespace doc as common.hpp doc in the index

* Wraps some of the C functions that libmraa has into the mraa namespace
* Not included in swig bindings as of yet
