note on __attribute__ ((nocommon))
AVR scripts often use --gc-sections on the linker to remove unused section.
This works fine for initialed data and text sections. In principle .bss is also
handled, but the name##_pb definition is not removed. Reason is, that
array definitions are placed in the COMMON section, by default
The attribute "nocommon" removes this automatic assignment to the
COMMON section and directly puts it into .bss. As a result, if more
than one buffer is defined in one file, then it will be removed with --gc-sections
.. not sure if Arduino IDE uses -fno-common... if yes, then the attribute is
redundant.
