306f8b5713 libutils: sp lh comparison w/ pointer
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.

5341172587 Add check to sp<> raw pointer constructor
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.

5f46923634 Trace.h: explicitly use global namespace
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.

1af6acc4d3 Use Android systemTime implementation for host linux.
The Android framework, notably android.view.Choreographer, assumes
that System.nanoTime and SystemClock.uptimeMills return consistent
values. This was true on device, but not on host.

This commit makes those values consistent on host linux. The necessary
support should be in place in kernels 2.6.39 and newer, which have been
available since 2012.

d4cb489434 libutils: Introduce StaticString16
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.

Bug: 138856262
Test: Run newly added unit tests.

454ba7ec88 Enable native_bridge_support for libutils
Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).

However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.

All needed modules have to explicitly indicate if they may be used as part
of translated binary build.

This change enabled native bridge support for libutils which is a
greylisted library (available for apps targeting Android version < N).

6e75ad6e13 Revert "Revert "Fix wp and sp comparison bugs""
Fix wp and sp comparison bugs

Make clear() actually clear wp m_refs, so that nulls compare equal.

Make equality consistent with < and >, ensuring that a weak pointer
cannot be both equal to and greater than another.

Don't rely on the built-in < and > operators to correctly order
different objects. The standard does not guarantee that, and there is
a risk of compiler relying on that lack of guarantee.

Remove unnecessary comparison overloads, especially those
comparing a wp<> to an sp<>.

Change the remaining wp<> to sp<> comparisons to check for equivalence
of the mRefs pointer instead of the object address, thus eliminating
the dubious equal comparison result for a dead wp<> and an sp<> that
happen to point to the same object address.

Add comparison tests.

This reverts commit a2a2ad8057.

The original code, and my original CL, both failed to initialize m_refs
in various wp<> constructors. This now became more important, since
comparisons now rely more on m_refs. However I believe it was always
a bug, since some comparisons always relied on m_refs.
