ftmod_isdn: Avoid stack smashing buffer overflow in isdn_tones_run().
The len variable can, in certain situations (large burst of incoming non-SLIN audio), exceed the size of the on-stack frame buffer, which causes ftdm_buffer_read_loop() to overwrite the dt_buffer pointer. Use ftdm_min() to make sure len (after conversion to SLIN units) isn't larger than the frame buffer size. Also adds are couple more code comments. Signed-off-by: Stefan Knoblich <stkn@openisdn.net>
