fhdl/verilog: fix representation of negative integers
...
Give the explicit two's complement representation for the given bit width.
This results in less readable code compared to using unary minus,
but fixes a bug when trying to represent the most negative integer.

__getitem__ as an exception that proves the rule ;)

sim: use Simulator as a contextmanager
...
__del__ garbage collector callbacks are too delicate. E.g. imported
modules can be garbage collected before the objects using them. Can't
use os.remove, socket.SHUT_RDWR...
* added a DeprecationWarning if a Simulator is garbage collected without
having its .close() called
* renamed all gc __del__ callbacks to close()
* implemented context manager hooks for Simulator. Use like
with Simulator(TestBench()) as s:
s.run()

({B}, [statement2])
