Add TEST_REQUIRE() and __TEST_REQUIRE() to replace the myriad open coded
instances of selftests exiting with KSFT_SKIP after printing an
informational message. In addition to reducing the amount of boilerplate
code in selftests, the UPPERCASE macro names make it easier to visually
identify a test's requirements.
Convert usage that erroneously uses something other than print_skip()
and/or "exits" with '0' or some other non-KSFT_SKIP value.
Intentionally drop a kvm_vm_free() in aarch64/debug-exceptions.c as part
of the conversion. All memory and file descriptors are freed on process
exit, so the explicit free is superfluous.

Take a vCPU directly instead of a VM+vcpu pair in all vCPU-scoped helpers
and ioctls.

Pass around a 'struct kvm_vcpu' object instead of a vCPU ID in s390's
memop test. Pass NULL for the vCPU instead of a magic '-1' ID to
indicate that an ioctl/test should be done at VM scope.
Rename "struct test_vcpu vcpu" to "struct test_info info" in order to
avoid naming collisions (this is the bulk of the diff :-( ).

Add a second underscore to inner ioctl() helpers to better align with
commonly accepted kernel coding style, and to allow using a single
underscore variant in the future for macro shenanigans.

The memop test currently does not have any output (unless one of the
TEST_ASSERT statement fails), so it's hard to say for a user whether
a certain new sub-test has been included in the binary or not. Let's
make this a little bit more user-friendly and include some TAP output
via the kselftests.h interface.

Do not just test the actual copy, but also that success is indicated
when using the check only flag.
Add copy test with storage key checking enabled, including tests for
storage and fetch protection override.
These test cover both logical vcpu ioctls as well as absolute vm ioctls.

In order to achieve good test coverage we need to be able to invoke the
MEM_OP ioctl with all possible parametrizations.
However, for a given test, we want to be concise and not specify a long
list of default values for parameters not relevant for the test, so the
readers attention is not needlessly diverted.
Add a macro that enables this and convert the existing test to use it.
The macro emulates named arguments and hides some of the ioctl's
redundancy, e.g. sets the key flag if an access key is specified.

Split success case/copy test from error test, making them independent.
This means they do not share state and are easier to understand.
Also, new test can be added in the same manner without affecting the old
ones. In order to make that simpler, introduce functionality for the
setup of commonly used variables.
