New Revision: 3281

URL: http://svn.digium.com/view/zaptel?view=rev&rev=3281
Log:
use a buffer for the span's device type instead of a string pointer, so each spans can have dynamically set device types instead of constant strings

also fix up some string creation and copying to be safe against buffer overflows
