In many ways it's weird and unwanted to keep all the tests in the same userfaultfd.c at least when still in the current way. For example, it doesn't make much sense to run the stress test for each method we can create an userfaultfd handle (either via syscall or /dev/ node). It's a waste of time running this twice for the whole stress as the stress paths are the same, only the open path is different. It's also just weird to need to manually specify different types of memory to run all unit tests for the userfaultfd interface. We should be able to just run a single program and that should go through all functional uffd tests without running the stress test at all. The stress test was more for torturing and finding race conditions. We don't want to wait for stress to finish just to regress test a functional test. When we start to pile up more things on top of the same file and same functions, things start to go a bit chaos and the code is just harder to maintain too with tons of global variables. This patch creates a new test uffd-unit-tests to keep userfaultfd unit tests in the future, currently empty. Meanwhile rename the old userfaultfd.c test to uffd-stress.c.
