r16550: Fix bug 3866. Thanks for the report!
Although I've never met a computer or compiler that produced pointers to
functions which are a different size than pointers to data, I suppose they
probably exist. Assigning a pointer to a function is technically illegal in C
anyway.
Change casts of the option_value based on the option_name to use of variable
argument lists.
For binary compatibility, I've maintained but deprecated the old behavior of
debug_stderr (which expected to be passed a NULL or non-NULL pointer) and
added a new option debug_to_stderr which properly expects a boolean (int)
parameter.
