Allocating the entire address space is sufficiently unreasonable that
hwasan blows you out of the water if you try to do that. Half the
address space feels like it's large enough to be guaranteed to fail
(which is all I think this intended to test) without being quite so
obviously incorrect that tools like hwasan are going to object...
...except hwasan actually has a 2GiB limit. So let's keep the cleanup,
but also just disable these tests if they're running under hwasan for
now.

The class being fuzzed here was too simple for a fuzzer to be effective at finding crashes that were not working as intended.
To resolve the issue noted in 163775285 would require the fuzzer to simply use RWLock exactly as intended, defeating the point of fuzzing it.
Because of this, we have made the decision to remove this class. It should have a fairly small impact on coverage. In the future,
perhaps a better approach would be fuzzing pthread's rwlock methods directly.
Test: Made sure the project still builds without RWLock_fuzz.

The input code is the only customer of PropertyMap. For easier
maintenance and eventual removal of it, move it to libinput.
Currently, the caller is responsible for managing the lifecycle of the
returned outMap when calling PropertyMap::load. However, the fact that
the function call allocates new memory is not obvious from the function
signature.
In a separate commit, I will refactor the function to return
Result<unique_ptr<>> to make it less errorprone.
In this commit, only move the files around to make code reviews easier.

In https://android-review.googlesource.com/c/platform/system/core/+/1224544
when we introduced a default argument to androidSetThreadPriority(),
we broke C compatibility with this API, and with the header file
in general.
We fix this up by instead introducing a new method that takes
three arguments. This gets this header file compiling for C again,
and keeps this particular API C compatible.
Any C++ callers of the three argument version of
androidSetThreadPriority() will need to switch to using
androidSetThreadPriorityAndPolicy(). Although since this was
a recent change, we believe there is only one such user, which
we are fixing at the same time.

I stumbled across this because of the `#ifdef __cplusplus` inside an
unguarded `namespace`, but this whole file should be deprecated and
removed in favor of static_assert.

For encoding errors, this function will return a negative value which
causes problems down the line. Check for an error and return. Also,
integer overflows are guarded.
