lib: introduce test_meminit module
Add tests for heap and pagealloc initialization. These can be used to
check init_on_alloc and init_on_free implementations as well as other
approaches to initialization.
Expected test output in the case the kernel provides heap initialization
(e.g. when running with either init_on_alloc=1 or init_on_free=1):
test_meminit: all 10 tests in test_pages passed
test_meminit: all 40 tests in test_kvmalloc passed
test_meminit: all 60 tests in test_kmemcache passed
test_meminit: all 10 tests in test_rcu_persistent passed
test_meminit: all 120 tests passed!
