String16 is still in use by AIDL compiler. Because String16 is not
noexcept-move-constructible, the C++ compiler will complain when it is
used with non-copyable types (such as ParcelFileDescriptor).
For example, when vector<Foo> is resized, copy-ctor of Foo is called,
which is not available.
parcelable Foo {
String s;
ParcelFileDescriptor[] pfds;
}
By providing noexcept move-ctor for String16, vector<Foo> can be resized
with no problem.
Btw, copy from StaticString16 is specialized for efficiency and move
from StaticString16 don't need to be different from copy.

This function, ironically, is being removed.
Even more amusing, it was never "remove" anyway --- it literally did
the opposite, and removed everything *except* the range you passed to
it, and should probably have been called "keep"!
I'm looking at reimplementing much of libutils, but first I'm improving
test coverage, and literally every test I wrote for this failed. And
then when I fixed the "obvious bugs" in the implementation, I found
there actually were a couple of existing unit tests --- that mostly
served to demonstrate just how counter-intuitive this function was.

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.

Newly allocated SharedBuffer already has reference count 1, so we

This is a backward compatible implementation of compile time
constructed String16 support.
As much as we'd like a regular constexpr constructor for String16, we
want to make sure the regular non-static String16 does not regress.
We also need to make sure prebuilts built with previous version of
String16 still works with new libutils. This means we cannot change
the size of String16 objects and we cannot make anything virtual.
To add a flag to indicate whether a String16 is static without
increasing the size of non-static String16 objects, we repurpose a
reserved field in SharedBuffer as "for client use". With this, we can
tag every String16 and perform memory operation differently based on
how the underlying buffers are allocated.
By using StaticString16, we are able to eliminate the runtime
construction of a String16 and move it out of .bss section.

Add utility methods that convert String16 and String8 into
std::string.
Also, remove a repeated include of <utils/Unicode.h> in
String16.h, since it is not used in that header file,
and is already included in String16.cpp.
