16-bit int fixes.
This fixes a number of issues for platforms with a 16-bit int, but
by no means all of them.
The type change for ec_window (for platforms where sizeof(size_t)==2)
will break ABI (but not API) compatibility with libsilk and libopus,
and reduce speed on x86-64, but allows the code to work in real-mode
DOS without using the huge memory model, which is useful for testing
16-bit int compliance.
