include files with the same name

["paul@wrada.com" <pa...@wrada.com>]

Hi all,

Just something I noticed here that I'll pass on to the group.

Mynewt has special directory structure to avoid name conflicts with header files.  For example,

Hal/hal_adc.h

And

Mcu/hal_adc.h

won't conflict because the user has to include the directory name in the path.

#include <mcu/hal_adc.h>
#include <hal/hal_adc.h>

However, my editor conveniently creates the #ifndef __FNAME__ directives in the header files.
Without some care, the example above will have problems because they will both use
__HAL_ADC_H__ as their include prefix.

I think by convention we can fix this with using a longer namespace in the header includes.

#ifdef __MCU_HAL_ADC_H__
#ifdef __HAL_HAL_ADC_H__
