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.

do not overload __len__, __iter__, __reversed__ as not all valid
expressions (ints and bools) have them. furthermore len([]) is and
should be different from flen([]) (the later raises an error). keep
__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()

group_by_target does not properly combine target groups if statements

({B}, statement2)
({A, B}, statement3)
which returns groups:
({A, B}, [statement1, statement3])
({B}, [statement2])
This patch fixes group_by_target such that the resulting group is:

module only must be remapped.
