 * The maple state is defined in the struct ma_state and is used to keep track
 * of information during operations, and even between operations when using the
 * advanced API.
 *
 * If state->node has bit 0 set then it references a tree location which is not
 * a node (eg the root).  If bit 1 is set, the rest of the bits are a negative
 * errno.  Bit 2 (the 'unallocated slots' bit) is clear.  Bits 3-6 indicate the
 * node type.
 *
 * state->alloc either has a request number of nodes or an allocated node.  If
 * stat->alloc has a requested number of nodes, the first bit will be set (0x1)
 * and the remaining bits are the value.  If state->alloc is a node, then the
 * node will be of type maple_alloc.  maple_alloc has MAPLE_NODE_SLOTS - 1 for
 * storing more allocated nodes, a total number of nodes allocated, and the
 * node_count in this node.  node_count is the number of allocated nodes in this
 * node.  The scaling beyond MAPLE_NODE_SLOTS - 1 is handled by storing further
 * nodes into state->alloc->slot[0]'s node.  Nodes are taken from state->alloc
 * by removing a node from the state->alloc node until state->alloc->node_count
 * is 1, when state->alloc is returned and the state->alloc->slot[0] is promoted
 * to state->alloc.  Nodes are pushed onto state->alloc by putting the current
 * state->alloc into the pushed node's slot[0].
 *
 * The state also contains the implied min/max of the state->node, the depth of
 * this search, and the offset. The implied min/max are either from the parent
 * node or are 0-oo for the root node.  The depth is incremented or decremented
 * every time a node is walked down or up.  The offset is the slot/pivot of
 * interest in the node - either for reading or writing.
 *
 * When returning a value the maple state index and last respectively contain
 * the start and end of the range for the entry.  Ranges are inclusive in the
 * Maple Tree.
 *
 * The status of the state is used to determine how the next action should treat
 * the state.  For instance, if the status is ma_start then the next action
 * should start at the root of the tree and walk down.  If the status is
 * ma_pause then the node may be stale data and should be discarded.  If the
 * status is ma_overflow, then the last action hit the upper limit.
