This branch adds an implementation of a singly-linked mutable FIFO `Stack`and a singly-linked lock-free FIFO `TransferStack` in `cordyceps::stack`. A `Stack` is just your traditional FIFO stack structure. `TransferStack` is a bit more interesting --- it's a simplification of the traditional lock-free Treiber stack wher all elements are popped into a new mutable `Stack` in a single atomic operation. This avoids the ABA problem issues common with naive Treiber stack implementations. It's intended primarily for use in a `mimalloc`-style sharded per-core memory allocator. Closes #137 Signed-off-by: Eliza Weisman <eliza@elizaswebsite>
