Andrew Kelley 7eeef5fb2b std.mem.Allocator: introduce remap function to the interface ...

This one changes the size of an allocation, allowing it to be relocated.
However, the implementation will still return `null` if it would be
equivalent to

new = alloc
memcpy(new, old)
free(old)

Mainly this prepares for taking advantage of `mremap` which I thought
would be a bigger deal but apparently is only available on Linux. Still,
we should use it on Linux.
