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%.

syslog messages should be written as <module>: Message in order to increase
readability and usefulness

* Fix a few resource leaks in error conditions
* Makes strtol() calls safer in pwm module
* Make sure buffer is terminated after read() in aio

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.

* Warning, doing a period call on the gen2 will change it for all pwm
* channels and temporarily disable them whilst doing it.

* Should allow for more platform quirks to be handled by mraa without
* massive conditional areas per platform.

* Allows for different bit shifting for each platform.
* New functions added for obtaining this information
* mraa_adc_raw_bits
* mraa_adc_supported_bits
* Update board information to include this. AIO module changed to allow
* use of the new board data
