Ticket 192: cfg_export dumps core on FreeBSD, Darwin

When attempting to evaluate libcfg for a project I'm starting, I ran the test on my FreeBSD 9 and OS X which dumped core. It looks like there's some incorrect usage of va_list variables given that the va_arg() call that initializes s on line 908 of cfg_fmt.c returns invalid memory. I put a va_copy() at the top of cfg_fmt_format(), making a copy of ap, and changed cfg_fmt_format() to operate on that copy. The test then passes. I'm not sure if this is the right solution, but at least the code runs and passes its test.
