Fixed memory leak when receiving network traces of 0xFFFF length
0xFFFF was used as a magic number in the length field of a network
message in order to trigger a resend. DLT library will now use the
nw_trace_type field and a custom type to do this, thus assuring no
external client of the library can reach this
value(DLT_NW_TRACE_RESEND).
