Patch to improve MAD subsystem

["Andrew V. Samoilov" <kai cmail ru>]

Hi!

This patch improves MAD subsystem, so it is possible now to
see where are g_strconcat, g_strdup_printf or g_strdup_vprintf
were called.

ChangeLog:

* mad.[ch] [__GNUC__] (mad_strconcat): Use macro varargs.
(mad_strdup_printf): Likewise.
(mad_strdup_vprintf): Likewise.

* main.c [HAVE_MAD] (main): Release this_dir and other_dir.
