mraa_i2c_init_internal() implenents logic of mraa_i2c_init_raw()
allowing mraa_adv_func_t to be passed in as a parameter
instead of of being global.

19d7dad364 i2c: remove smbus helper library & clean up command use in API 
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

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.
