These arguments were originally just to make sure arguments could be
successfully passed to sc_main, but serve no intrinsic purpose. There
are some tests which can accept command line arguments to customize
how they run, and having nonsense arguments confuses them and makes
them behave incorrectly.

The golden reference output for the test was to throw an error which
is clearly not at all related to the test (it was about immediate
self notifications while the test never calls any form of notify())
and which would happen significantly before the end of the test,
negating all the other behaviors and checks which would happen after
that point.
Since it strongly looks like the reference output was updated in error,
and because other very similarly structured tests are expected to run
silently except for printing "Success" at the end (which it does when
run under gem5), this change manually updates the golden reference
output to reflect what appears to be correct.

If an exception escapes sc_main, Accellera catches it and feeds it
into the report handler, telling it to run the catch actions. This
seems like it sets up lots of dangerous scenarios, and also makes a
vital error detecting path more complex and error prone.
On the other hand, it makes one of the tests pass.

This typo was added purposefully to match Accellera's output, but then
it was discovered that some test's golden output had the typo, and some
didn't. That must mean that not all tests have up to date output, and
that Accellera couldn't possibly pass all of their own tests.
To resolve this conflict, this change fixes the typo and manually
updates all the golden output.

Something the Accellera implementation does which would be good to do
in the gem5 implementation is to create a base class for sc_signal
which isn't templated, and which holds the common/non-type specific
versions of the various sc_signal methods. This will reduce code
redundancy and binary size, and also let us hide more code in .cc
files so that it's less likely we'd need to recompile model code to
fix a bug.
Also, since this all uses of sc_channel_warn_unimple have now been
eliminated, remove that function.

In the Accellera implementation, every time a delta cycle is traced a
check is done to see if the user has been told what the pseudo timestep
is. To avoid doing that check over and over, we'll leave that out and
tell the verify.py to ignore that message in the reference output.

By centralizing module callbacks, the gem5 module class knows when
different stages of the simulation are happening and can do it's own
extra checks. It also compartmentalizes modules more since the kernel
object doesn't have to reach into them to enumerate ports and exports.

This change tightens up exception catching and makes gem5's systemc
code react to exceptions more in line with the Accellera
implementation. This prevents exceptions from being caught by the
pybind11 integration which makes it very difficult to see where an
exception came from, and makes the output differ by including a
(mostly useless) backtrace.

The golden output for tests doesn't distinguish between stderr and
stdout, and by only comparing against stdout we have to throw away
errors which would be good to verify we get right. Also the tests
sometimes send output to stderr for no apparent reason, requiring
manually patching the tests.
This change adds filters for two messages which used to go to stderr
in gem5 but now show up in the diffs, one that just says the simulation
is starting, and the other for warns of unimplemented functionality.
The second warning should be turned on at some point so we make sure
everything the tests touch works and they don't just work by
coincidence, but for now it introduces a lot of noise among otherwise
passing tests.

Accellera's implementation prints any sc_report which is thrown and

Arguably gem5 should fail if sc_main reports an error, but verify.py

purposefully generate errors.
This change also stops using the logging module. It wasn't really
