toUpper() separately, since it's so easy.

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.

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.

Most of the built-in functions return signed values but BitSet deals
only in unsigned values. We can safely cast these away though as they're
always indices, which can't be negative.

This is in preparation of doing what we did for SharedRefBase (hiding
operator new) so that clients can't accidentally construct
shared_ptr/unique_ptr or any other alternative memory management scheme
which would conflict with RefBase. You can see what ultimately happened
to SharedRefBase in frameworks/native CL
10d9ddf2e3da3ba3a425fb8396aaaec728e5fbdb.
The goal for this:
- promote use of 'sp<T>::make' over 'sp<T> .. = new T'
- make 'operator new' a private member of RefBase

Perhaps the better question is, why have I 100s of times, typed
"ASSERT_NE(nullptr, foo)" for sp<> foo, and got a compiler error and
then change it to "foo.get()". This CL so we can stop wasting cycles
with that error.

For the raw pointer constructor, check that the argument is not on the
stack. Passing a stack pointer as an sp<> parameter is dangerous,
since we will attempt to deallocate the object once the sp<> is no
longer needed. We approximate ste stack ccheck by testing whether it
is on the same page as the frame pointer.
Do the same for raw pointer assignment.

Imagine an AIDL file:
package android.foo;
interface IFoo {}
The AIDL C++ backend will generate classes like "::android::foo::IFoo".
In order to avoid ODR conflict, the NDK (Stable C) backend linking
against libbinder_ndk puts everything under the "::aidl" namespace. So,
we have "::aidl::android::foo::IFoo". When using ScopedTrace in a class
implementing a class from this backend, there is this problem.
