Try to clean up the code paths coming in and out of binder IPCs to
plug any places where we could disrupt the gather flag of a thread,
causing it to keep gathering stack crawls (which is the thing that
is causing our strict mode data to become so large).
We now take care of saving and restoring this state in the core
IPC code path, not at the Java layer.

Cast away the const qualifier in BBinder::findObject. C11, unlike C++11,
does not allow loads from const atomics. This is widely regarded as
a bug (see WG14 DR 459). This is a hack to work around it until it's
officially fixed in the spec.
load_const_atomic was adapted from commit
1e8587a479fd8b1ce9b594298a93f517816e8f15
I don't think we want to dignify this by putting it into a header file.

After fixing b/16874785.
This reverts commit f010a05c7e.
Original comment, which actually describes the effect of this:
Change the mExtras field in Binder.h to be a stdatomic.h atomic
value, and replace references to it with proper stdatomic.h calls.
This removes one of a small number of remaining 64 bit
android_atomic references. It also replaces the erroneously
non-atomic read accesses to mExtras.
It would be better if this used the C++11 <atomic> facility,
but we don't quite have that yet.

It can help to detect some kind of error, such as why GraphicBuffer::flatten
will crash when handle is null.

These weren't really being used and they make it
very hard to reason about who looks at command line
arguments.
Processes started via app_process (this includes all
zygote forks and the system_server) can get information
about command line arguments from the AndroidRuntime
class, which is available via a call to
AndroidRuntime::getRuntime.

Revert "Fix "Binder: Make sure binder objects do not overlap" to work old binder kernel interface"
This branch has the new driver interface so it should not have this change.
This reverts commit 6790329358.
Change-Id: I9b6d0d653d98dbdb521ef964c5e7c2f14859d340
When using 64 bit binder pointers, only initializing the 32 bit
handle, in a stack allocated struct, will pass uninitialized stack
data to the kernel and other processes.
Change-Id: I3432d9d36bb251d8ddb0a863661aeb80aabb3d92
When using the 64 bit binder interface from a 32 bit process the
pointer may get sign extended and cause the kernel to fail to read
from it.

IPCThreadState does not handle driver errors, and will resend the failed

Changes include
- Binder attempts to cast pointers to a int datatype
which is not sufficient on a 64-bit platform.
- This patch introduces new read/write functions into
Parcel that allow pointers to be written using the
uintptr_t datatype for compile-time data type size
selection.
- Change access specifier for the methods above.
- Binder uses the 64bit android_atomic_release_cas64
(aka cmpxchg)
