20d229168b gpio: mraa_gpio_dir allow output to set val 
There is an issue that when you take an IO pin that has an external PU
resistor and switch it from INPUT to OUTPUT the state of the pin will go
down before you can set it back high.

57540cd86c gpio.c: check that real gpio did initialise correctly 
On platforms without muxing perform a little more checking when the 'real'
linux/sysfs gpio is opened. We don't expect this to fail but on platforms where
the linux gpios can be changed depending on pinctrl/bios configuration this
might not always be the case.

3865bebe8d mmap: remove implementation of mmap gpio 
Instead of trying to have an implementation that covers most platforms
Leave all mmap up to platform definition. Through function pointers.

gpio_mmap_setup sets up the mmap

Within the internal gpio context struct two more function pointers now
exist mmap_read & mmap_write. They exist there so each context can its
own function for handling a write and read.

32d8a6f0ca syslog: remove all fprintf calls and use syslog instead 
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.
