ipcpd: Revise Data Transfer component0.10.0

This makes the TTL non-optional and allows the maximum (initial) value
of the TTL to be specified at bootstrap (the default is set to
60). The fd in the DT PCI is now called EID (Endpoint ID). The names
"dif" and "ae" have been replaced by "layer" and "component"
respectively in all sources.
