modifications to write a whole file cfg
restored original DotGraph implementation
attempt to capture method calls also in return statements
generalized printer mechanism and generate CSV files as option
added linker for CFGs
main project to link the graph for Busybox
fix format problems (missing ;)
use .pc files when constructing large CFG
propagate CIgnore types better (prevent error output)
fix error reporting of incorrect function signatures (without types)

was assert before introduced with the assumption that
functions without typed paramters can only occur with old-style parameters

massive refactoring of CType

now a two-level structure. CType is the wrapper which takes
care of object and storage modifiers, whereas AType is
the old CType without CObj and represents the basic types
