test_actor: add unittests for SimActor
...
* also implicitly tests for the access of signals during simulation that are
not referenced in any statements
* before, if the busy signal is never used, it is stripped
and could not be accessed in simulation

sim: keep track of unreferenced items
...
* items that are never referenced in any statements do not end up in the
namespace or in the verilog
* this memorizes items if they can not be found in the namespace and keeps
track of their values

Revert "fhdl/verilog: do not use initial begin in _printinit (not accepted by all synthesis tools ex: Synplify Pro does not accept it)"

This breaks simulations, and we will try to use the "reg name = value" syntax instead.
This reverts commit e946f6e453

fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code
...
it's generally better to have identical code between simulations and synthesis, but here tricks inserted for simulation are clearly expected to be simplified by synthesis tools, so it's better not inserting them.
