slirp: call into g_debug() for DEBUG macros

Make slirp use GLib logging, instead of fprintf(), so that
applications can filter log, process it etc.

With recent versions of glib, G_MESSAGES_DEBUG must be set to "all" or
"Slirp" to see slirp debug messages.

Reformat DEBUG_MISC & DEBUG_ERROR calls to not need \n ending.
