#332 Error reading from TSN PD header

[Anders Öberg]

In function trdp_pdReceive at lines 862, 869, 877, 950 (trdp_pdcom.c commit 2168) there is no support fora a TSN PD header.
A received message can ether have a header of type PD_HEADER or PD2_HEADER, all data read from the header has to consider the type.
A good solution to avoid mistakes in later updates of the sources is to copy the data to a temprery header type or use pointer to the variables in the header so the funcitons only needs to consider the header type once.

Fixed the handling of TSN header fields in pdReceive.
