check if device matches the ashmem rdev, before calling
ashmem_get_size_region. This eliminates making this call
when associated with other driver file descriptors.

check if device is a character device, before calling
ashmem_get_size_region. We do not check if the st_rdev
matches /dev/ashmem. So this at least eliminates making
this call when associated with a socket.

Sending transaction to freed BBinder through weak handle
can cause use of a (mostly) freed object. We need to try to
safely promote to a strong reference first.

The addition of ashmem size tracking can lead to parcel objects
overwriting other values on the stack in old binary blobs.

Makes sure we don't change the memory layout of the Parcel class
to maintain binary compatibility with prebuilts linking against
libbinder.

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.

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.
