 * Translating the names of the 'i' functions:

 *     a: arena (query)
 *     s: size (query, or sized deallocation)
 *     e: extent (query)
 *     p: aligned (allocates)
 *     vs: size (query, without knowing that the pointer is into the heap)
 *     r: rallocx implementation
 *     x: xallocx implementation
 *   Abbreviations used in the second part of the function name (after
 *   alloc/dalloc) describe the arguments it takes
 *     z: whether to return zeroed memory
 *     t: accepts a tcache_t * parameter
