Improve the svm fifo allocator
- Round up requested fifo size to the next power of two - Maintain per-segment power-of-two freelists - Allocate fifos in chunks, to amortize alignment overhead - Detach builtin test client application after each run so we can use different fifo sizes each time - Be more suspicious of session / application indices Useful prep work for dynamically resizing fifos. As far as the svm fifo code is concerned, it's OK to set fifo->nitems anywhere in the interval: [0, 1<<(fifo->freelist_index) + FIFO_SEGMENT_MIN_FIFO_SIZE] It's unlikely that setting nitems below the path MTU will work out very well...
