Adds fuzzers for BitSet, FileMap, String8, String16, and Vector.
Test: Ran fuzzers on Android Pixel 3a. Aggregate coverage was 1.2% (this is far lower than true coverage due to shared libraries being counted)

Modules contributing mainline modules (APK/APEX) should set
min_sdk_version as well as apex_available.
For now setting min_sdk_version doesn't change build outputs.

The marked library(ies) were available to the APEXes via the hand-written
whitelist in build/soong/apex/apex.go. Trying to remove the whitelist
by adding apex_available property to the Android.bp of the libraries.
In this change, following libs were made available to all apexes because
their usage is quite common and there is no reason to restrict them
to some APEXes.
* libbase_headers
* libcutils, libcutils_headers
* libutils_headers, libsystem_headers
* liblog_headers
* libbacktrace, libbacktrace_headers

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

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.

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.

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.

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).
