[iobuf] Improve robustness of I/O buffer allocation
Guard against various corner cases (such as zero-length buffers, zero
alignments, and integer overflow when rounding up allocation lengths
and alignments) and ensure that the struct io_buffer is correctly
aligned even when the caller requests a non-zero alignment for the I/O
buffer itself.
Add self-tests to verify that the resulting alignments and lengths are
correct for a range of allocations.
