Closes #325 Add a new subid_init() function which can be used to specify the stream on which error messages should be printed. (If you want to get fancy you can redirect that to memory :) If subid_init() is not called, use stderr. If NULL is passed, then /dev/null will be used. This patch also fixes up the 'Prog', which previously had to be defined by any program linking against libsubid. Now, by default in libsubid it will show (subid). Once subid_init() is called, it will use the first variable passed to subid_init(). Signed-off-by: Serge Hallyn <serge@hallyn.com>
