Remove references to sbrk to grow/shrink arenas
The manual incorrectly references sbrk as the method used to grow and shrink heaps and the fact that M_TRIM_THRESHOLD and M_TOP_PAD control that behavior. In reality, a heap may be grown or shrunk through multiple methods depending on whether it is the main arena (in which case sbrk is correct) or not (in which case, there are a number of strategies including allocating an additional heap to grow an arena and/or 'mprotect' a region to make it available for allocation). Remove references to sbrk so that it covers the behavior more accurately. * manual/memory.texi (M_TOP_PAD): Remove reference to sbrk. (M_TRIM_THRESHOLD): Likewise.
