can: Add big endian CAN frame layout handle

- can-decoder.cpp: translate_signal() : Tests "frame_layout_is_little".
If false the signal's bit position is changed to fit the layout.

- message-definition.cpp: Added the new attribute
"frame_layout_is_little" and its getter.

- signals.cpp: Added a setter to the bit_position attribute.

- converter.cpp: Added a methode to convert a big endian bit_position
to a right (little endian) bit_position.
