68604b9c29 Fail explicitly on length overflow.
Instead of aborting when FileMap::create detects an overflow, detect the
overflow directly and fail the call.

Bug: 156997193

Test: Ran unit tests, including new unit test that aborted before.

9d5845bb5e Add fuzzers for libutils classes
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)

Change-Id: I739216fe88afa51dc2f73b857da91116853382f0

Removed unneeded cflags, moved libbase to defaults

Modules contributing mainline modules (APK/APEX) should set

a206b8cbf4 Set apex_available property
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

401d69aa94 libutils: introduce sp<T>::make
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

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.
