The memory API supports 64-bit buses (e.g. PCI). A size on such a bus cannot
be represented with a 64-bit data type, if both 0 and the entire address
space size are to be represented. Futhermore, any address arithemetic may
overflow and return unexpected results.
Introduce a 128-bit signed
Since the memory API supports 64-bit buses, it needs a larger type to represent
intermediate results.

In order to solve the recurring overflow issues with the memory API,
introduce a 128-bit integer type to hold sizes (range 0 - 2^64) and
intermediates. While the patchset does reduce readability, I believe
it is the only way to prevent overflows emerging in unlikely places in
the code.
