This reverts commit 6d1da867e6 ("tests/migration: Reduce autoconverge initial bandwidth")
since that change makes unit tests much slower for all developers, while it's not
a robust way to fix migration tests. Migration tests need to find
a more robust way to discover a reasonable bandwidth without slowing
things down for everyone.

migrate_get_socket_address() neglects to check
visit_type_SocketAddressList() failure. This smells like a leak, but
it actually will crash dereferencing @addrs. Pass &error_abort to
remove the code smell.

Per David Gilbert, "it could just be the writing is slow on s390
and the migration thread fast; in which case the autocomplete
wouldn't be needed. Perhaps we just need to reduce the bandwidth
limit."
Tuning the threshold by reducing the initial bandwidth makes the
autoconverge test pass.

There's an assert in autoconverge that checks that we quit the
iteration when we go below the expected threshold. Philippe
saw a case where this assert fired with the measured value
slightly over the threshold. (about 3k out of a few million).
I can think of two reasons:
a) Rounding errors
b) That after we make the decision to quit iteration we do one
more sync and that sees a few more dirty pages.
So add 1% slack to the assertion, that should cover a and
most cases of b, probably all we'll see for the test.

Commit e51e711b1b has moved the initialization of start_address and
end_address after the definition of the command line argument,
where the nvramrc is initialized, and thus the loop is between 0 and 0
rather than 1 MiB and 100 MiB.
It doesn't affect the result of the test if all the tests are run in
sequence because the two first tests don't run the loop, so the
values are correctly initialized when we actually need them.
But it hangs when we ask to run only one test, for instance:
QTEST_QEMU_BINARY=ppc64-softmmu/qemu-system-ppc64 \
tests/migration-test -m=quick -p /ppc64/migration/validate_uuid_error

The tests directory itself is pretty overcrowded, and it's hard to
see which test belongs to which test subsystem (unit, qtest, ...).
Let's move the qtests to a separate folder for more clarity.
