allow tonezone to live in a different place than DAHDI/Zaptel, since dahdi-tools and dahdi-linux are now separate packages and can be installed in different places

don't include tonezone.h in dahdi_compat.h, because only a couple of modules need it

get app_rpt building again after the DAHDI changes

(closes issue #12911)
