6626# Add shared_port_daemon binaries and basic config lines
Move SHARED_PORT_DAEMON_AD_FILE into  GLIDEIN_LOCAL_TMP_DIR.

This way it is guaranteed to be on the local file system, and short enough.
(UNIX limits require a path of less than 90 chars)
6626# Add support for enabling the shared_port daemon.

There is a new knob, USE_SHARE_PORT that triggers it.
It is processed by setup_firewall.sh, a new script loaded by the glideins.
I have moved USE_CCB in it as well, and out of collector_setup.sh, as it does not need to be process that early in the execution chain.
6626# Document USE_SHARED_PORT
6626# Rename setup_firewall to setup_network
6626# Fix comments
6626# Stage setup_network.sh
