writeByteArray writes the size using sizeof(size_t), however it is always
read using readInt32(). On devices where sizeof(size_t) != 4 this causes
extra bytes to be written.

Make sure that we don't go haywire if an exponential buffer growth
operation winds up wrapping integer range. Along the way, fix a
bookkeeping bug in BufferedTextOutput that would cause it to keep
spuriously realloc()ing on every append().

We now check for fd-legality before committing binder objects to
the flattened data buffer rather than after. Previously we would
wind up corrupting the parcel and incurring driver-level errors,
as well as potentially leaking FDs.

Add functions to allow a client to take over the ashmem region
that was transferred so that it can claim it for its own and
reuse it.
Add support for mutable ashmem regions too.

Attempts to replicate Java parceling in native code is fraught with
peril.

(cherry picked from commit f47a381001)
When appending one parcel's contents to another, ignore binder
objects within the source Parcel that appear to lie beyond the
formal bounds of that Parcel's data buffer.

The inputs to native_handle_create can cause an overflowed allocation,
so check the return value of native_handle_create before accessing
the memory it returns.

It's a security best practice for size_t values to be rejected if
they are greater than INT32_SIZE. This is intended to prevent the
common error of inadvertently passing a negative int value to a
function, which after conversion to an unsigned type, becomes a huge
number, defeating the purpose of bounds checking.
This patch also addresses a bug where the call to:
Parcel::write(buf, (size_t) -1);
would call writeInPlace() which uses PAD_SIZE on the supplied
argument. This would then cause an integer overflow, with PAD_SIZE
returning a small value, but the memcpy in Parcel::write using the
old large length value.

When compiling 32 bit binaries against a 64 bit binder interface,
implicit promotions of intptr_t types to uint64_t for fields in the
binder ioctl structures can result in invalid pointers because of sign
extension.
Adds readUint32 and writeUint32 methods to the Parcel class. This
saves a lot of static_casting in anything implementing a Binder
interface on the native side.

Now that we're in C++11 mode by default, clang complains about switch
statements with case values not matching the type -- since some
binder_driver_return_protocol values are > 0x7fffffff, we need to make
the switch statements operate on uint32_t rather than int32_t.

* Explicit conversion for atomic_uintptr_t initialization.
* Fix string literal concatenation to not be a UD literal.
* Use __typeof__ instead of typeof (should become decltype once this
actually moves to C++11).

to use the new static version.
