Parcel.cpp: reject size_t arguments greater than INT32_MAX

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.
