Change the defaults in verify.py to be more like how I've been running
it. This is as close of an approximation as I have to how someone else
would want to run it manually. When run as part of a script, it's less
cumbersome to have to add extra arguments.

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.

It's possible for a test to generate a warning or error in the middle
of a line of output. The previous filter generator function would
create a filter which would only detect those messages which started
at the beginning of a new line.

The Accellera implementation runs processes in a cycle where it first
runs all the methods it has, then all the threads, and then starts
again in case any new methods have been scheduled. This keeps methods
and processes in the order they were marked ready (what a prior change
made this scheduler do), but also keeps the methods together and the
threads together (something it used to do, but that change made it
stop doing). This change should make the gem5 scheduler match in both
respects.
Note that its correct to run the processes in whatever order we want,
it's just that if we're going to compare against the "golden" output
from the Accellera tests, we need to match the order to get sensible
results.

This is totally legal and good for performance, but because some of
Accellera's tests depend on processes which can run in any order
running in a particular order to reproduce the golden output, it needs
to be disabled to pass the tests.
This change leaves it as an option which could even be plumbed out in
the future to support some sort of "compatibility" mode with the tests.
An alternative would be to verify that the tests pass, change the
ordering to the alternative (but still correct) order, and then
update the reference output.

This has three advantages. First, the data structure doesn't have to
try to keep track of whether or not an event is already listed there.
Second, it's easier to delete an item by storing an iterator for it
when it gets inserted. Third, the ordering of events is not dependent
on the arbitrary ordering of the set, it's bsaed on the fixed order
the events get added to the list.
One part of this change makes ScEvent-s keep track of what list they're
on, and handle their own insertion and deletion when they're
scheduled or descheduled. A side effect of that is that it's no longer
safe to simply use a range based for loop to loop over all of an
ScEvent and deschedule all its events or to run then (which deschedules
them internally once they execute).
That can be avoided by looping until the list is empty, and operating
on the first element. As the first element is processed and removed
from the list, the next element will become first and will get picked
up in the next iteration.

The print function is supposed to print both pending and committed
writes, apparently.
Accellera's implementation of sc_fifo uses a ring buffer to store the
entries and manages a head and tail pointer to keep track of what's
full, etc. Their dump function prints that whole buffer using the
indexes. When not using a ring buffer, there's no easy way to determine
what those indexes should be.
Fortunately the test that uses dump never moves away from the base of
the ring buffer, so I can get the same effect (which also makes sense
on its own) by printing the index into the fifo instead.
