Fix initialisation order
...
Initial processes set a magic flag in the code generator
which allows it to push constant assignments into the
VHDL signal initialisation and omit the assignment.
However, it should only do this if the signal has not
already been read (otherwise the previous read would
not get the undefined value as expected)

Allow ouput to be read if connected to child output
...
If output P of A is connected to output Q of B (and A is
instantiated inside B) then VHDL does not allow B to read
the value of Q (also P), but Verilog does. To get around
this the output Q is mapped to P_Sig which is then connected
to P, this allows B to read the value of P/Q via P_Sig.
