fhdl/decorators: make the transform logic more idiomatic
...
* the transformers work on classes and instances.
you can now do just do:
@ResetInserter()
@ClockDomainRenamer({"sys": "new"})
class Foo(Module):
pass
or:
a = ResetInserter()(FooModule())
* the old usage semantics still work
* the old DecorateModule is deprecated,
ModuleDecorator has been refactored into ModuleTransformer
(because it not only decorates things)

not referenced in any statements

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

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

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.
