The migration tests have a set of core infrastructure routines. These
are functions that are called by (almost) all tests and centralize the
common operations of: starting migration on both sides, waiting for
guests to boot, performing guest initialization and teardown, guest
memory validation, etc.
Move this basic framework code (and a few static helpers) into a
separate file. Leave only individual test functions (and their own
static helpers) in migration-test.c.

We currently have some environment validation to perform and flags to
set during the initialization of the tests. To be able to add more
migration test binaries, we'll need these tasks to be in their own
function so they can be called from more than one place.
Move the initialization code to a function and introduce the
MigrationTestEnv structure to hold the flags that are accessed during
test registration.
Make the env object static to avoid have to change all the code to
pass it around. Similarly with the tmpfs variable, which is used
extensively.
Note: I'm keeping the new functions in migration-test.c because they
are going to be moved in the next patch to the correct place.

We current have a bunch of non-test functions in migration-test.c and

The current build structure for migration tests is confusing. There is
the tests/migration directory, which contains two different guest code
implementations, one for the qtests (a-b-{bootblock|kernel}.S) and
another for the guestperf script (stress.c). One uses a Makefile,
while the other uses meson.
The next patches will add a new qtests/migration/ directory to hold
qtest code which will make the situation even more confusing.

directory and rename the old one to tests/migration-stress.

Test frameworks usually prefix "test_" to the entry point of the test

We have several qtest tests which want to reset the QEMU under test
during the course of testing something. They currently generally
have their own functions to do this, which work by sending a
"system_reset" QMP command. However, "system_reset" only requests a
reset, and many of the tests which send the QMP command forget the
"and then wait for the QMP RESET event" part which is needed to
ensure that the reset has completed.
Provide a qtest_system_reset() function in libqtest so that
we don't need to reimplement this in multiple different tests.
A few tests (for example device hotplug related tests) want to
perform the reset command and then wait for some other event that is
produced during the reset sequence. For them we provide
qtest_system_reset_nowait() so they can clearly indicate that they
are deliberately not waiting for the RESET event.
