Make strdump(), csidump(), print to stderr
The two functions strdump(), csidump() are called to show errors and their output is introduced by a message printed to stderr. Thus, it it more consistent to have them print to stderr. Moreover stderr is unbuffered (at least on Linux), making problems immediately visible.
