	Make strdump(), csidump(), print to stderr

	The two functions strdump(), csidump() are called to show errors and
	ttheir 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.
