New Revision: 48067

URL: http://svn.digium.com/view/asterisk?view=rev&rev=48067
Log:
in the helper thread, separate the FILE * creation from the actual
function doing work on the socket. This is another generalization
to provide a generic mechanism to open TCP/TLS socket with a thread
managing the accpet and children threads managing the individual
sessions.
