migen.fhdl.structure: add Signal.like(other)
...
This is a convenience method. Signal(flen(other)) is used frequently but that
drops the signedness. Signal((other.nbits, other.signed)) would be correct but
is long.

genlib/fifo: add flush, expose level in SyncFIFO

AsyncFIFO would need versions of flush and level in each clock domain
plus some handshaking on double flush.

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

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()
