QDataStream::readBytes(): make the growth of the buffer geometric
The algorithm tries to allocate the memory using 1 Mb blocks.
When the input data is large, this results in a lot of reallocations,
which is slow and inefficient.
This patch modifies the algorithm in such way that the allocation size
increases at each step, resulting in geometric growth of the buffer.
