Convert rtree from (void *) to (uint8_t) storage. Reduce rtree memory usage by storing booleans (1 byte each) rather than pointers. The rtree code is only used to record whether jemalloc manages a chunk of memory, so there's no need to store pointers in the rtree. Increase rtree node size to 64 KiB in order to reduce tree depth from 13 to 3 on 64-bit systems. The conversion to more compact leaf nodes was enough by itself to make the rtree depth 1 on 32-bit systems; due to the fact that root nodes are smaller than the specified node size if possible, the node size change has no impact on 32-bit systems (assuming default chunk size).
