This API was tested before, but it wasn't used until it is needed in
libbinder. Previously it passed the tests because wp::operator==
compares weak_ptrs which are never deleted, but it doesn't check the
value of m_ptr as well. This assumes that the RefBase implementation is
self-consistent.
Future considerations:
- add additional CHECK (perf?)
- add an additional optional CHECK?
- update all refbase tests to use an embellished form of this operator

If you need to do a case transformation for a Unicode string, you need
to use icu4c. This only worked for ASCII, which is just silly. Luckily
it doesn't seem to be used anywhere.

Previously, sp::sp(T*) internally had a static cast, and people
frequently wrote code like this:
sp<A> a = ...;
sp<B> b(a.get()); // implicit static cast
Luckily, none of the other sp constructors have this implicit cast. So,
for explicit code, rather than making those use static_cast internally,
adding an sp::cast function.

In form, inspired by ANDROID_BASE_UNIQUE_FD_DISABLE_IMPLICIT_CONVERSION.
We get occasional bugs about sp double-ownership. When this flag is
enabled, we have:
- you must construct RefBase objects using sp<>::make
- you must construct wp<> objects by converting them to sp<>
- if you want to convert a raw pointer to an sp<> object (this is
possible since the refcount is used internally, and is used commonly
on this*), then you must use 'assertStrongRefExists' semantics which
aborts if there is no strong ref held. That is, if a client uses
std::make_shared and then calls a function which internally used to
call `sp<T>(this)`, you would now call
`sp<T>::assertStrongRefExists(this)`, and the double ownership
problem would become a runtime error.

vendor_available modules were available to product modules.
However, not all vendor_available modules are required to be
available to product modules. Some modules want to be available only
to product modules but not vendor modules.
To cover the requirement, we separate product_available from
vendor_available.
vendor_available will not provide product available module.
Rename libcutils/include_vndk to libcutils/include_outside_system as
it provides the headers to the modules outside the system partition
including /product.

This requires a few other changes to support building libutils
properly. It does appear the windows versions of libutils is
referencing CallStack code, but it doesn't seem to cause any problems.
However, I removed those references completely for the windows build.
Also removed a few extra spaces that seem to have accumulated in the
RefBase.cpp.

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.
