Extracted helper functions and bitmasks into separate compilation unit

* utility.h and utility.cc now contain the UTF8-codepoint and unit bitmasks and read / write functions
* Modified users of these functions and unions accordingly
* Added the new compilation unit to the Makefile
* Changed bitmask specification from plain integer literals to shift expressions for better readability
