Before this change, pseudo TAs only supported the multi-session

This change will be required for the secure data path (SDP) support.
It allows a TA to be invoked with parameters referring to SDP

pseudo TA was badly declared, including UUID overlapping between

The rshift(), strtonum() and and() functions are GNU extensions to awk.

Replace the awk calls with bash arithmetic to avoid any issues. We know
we can rely on the shell being bash, since the main Makefile has
