25 This function shall install a new memory allocator to be used by Libb‐
26 son.

28 For backwards compatibility, if vtable->aligned_alloc is not set, calls
29 to vtable->aligned_alloc will use vtable->malloc instead.

31 WARNING:
32 This function MUST be called at the beginning of the process. Fail‐
33 ure to do so will result in memory being freed by the wrong alloca‐
34 tor.
