QDataStream: add a new SizeLimitExceeded status code
This status is supposed to be used when the stream tries to read
or write more data than it is supported by the current platform.
For example, reading more than 2 GiB of data on a 32-bit platform will
result into this status, but it will work fine on a 64-bit platform.
This patch uses the new status in read operations.
