Migration capabilities are set in multiple '.start_hook'
functions for various tests. Instead, consolidate setting
capabilities in 'migrate_start_set_capabilities()' function
which is called from the 'migrate_start()' function.
While simplifying the capabilities setting, it helps
to declutter the qtest sources.

Add a new command line option to allow selecting between running the
full set of tests or a smaller set of tests. The default will be to
run the small set (i.e. no comand line option provided) so we can
reduce the amount of tests run by default. Only hosts which support
KVM for the target architecture being tested will run the complete set
of tests.
Adjust the meson.build file to pass in the --full option when
appropriate.
(for now, set the option unconditionally until the next patch actually
creates the small set)
Use cases:
configure --target-list=aarch64-softmmu,ppc64-softmmu,s390x-softmmu,x86_64-softmmu
| before - 615s/244 tests | after - 244s/100 tests
------------------------+--------------------------+-----------------------------
make check | full set for all archs | full set for the KVM arch,
make check-qtest | | small set for the rest
| |
qemu-system-$ARCH | full set for $ARCH | small set for $ARCH, KVM or
./migration-test | | TCG automatically chosen
| |
qemu-system-$ARCH | N/A | full set for $ARCH, KVM or
./migration-test --full | | TCG automatically chosen

Add a migration test for cpr-transfer mode. Defer the connection to the
target monitor, else the test hangs because in cpr-transfer mode QEMU does
not listen for monitor connections until we send the migrate command to
source QEMU.
To test -incoming defer, send a migrate incoming command to the target,
after sending the migrate command to the source, as required by
cpr-transfer mode.

In real use cases, the migrate-recover command requires out-of-band
execution, because the thread processing normal commands is blocked by a
page fault in the guest memory. With this change, the tests will be
closer to real use cases and could help detect regressions and other
bugs in migration recovery.

Move the remaining tests into a misc-tests.c file. These tests are
mostly about validation of input and should be in the future replaced
by unit testing.

Move the mode/reboot test into a separate file to hold all the CPR
tests. Currently there's just one test, but we're adding more CPR
modes and the feature is different enough from live migration that
it's worth it to have a separate file for it.

Split the file tests from migration-test.c. These are being moved to

The migration-test.c file has become unwieldy large. It's quite
confusing to navigate with all the test definitions mixed with hook
definitions. The TLS tests make this worse with ifdef'ery.
Since we're planning on having a smaller set of tests to run as smoke
testing on all architectures, I'm taking the time to split some tests
into their own file.
Move the TLS tests into a file of their own.

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.
