svm: fix multi-chunk fifo alloc and add more tests
Type: fix - make sure that chunks and the rbtree are initialized if fifo segment allocates multiple chunks for the fifo. - ensure head/tail chunks are updated on all enqueue/dequeue events, including when dropping data. - more unit tests Also fixes dequeue drop updates of head chunk.
