Subject: [C23 new stdlib 1/3] C23: add the new interfaces free_sized and free_aligned_sized for stdlib.h
For the moment, these are just trivial wrappers that ignored their
parameters other than the pointer.
The names were not previously reserved, so they could generate naming
conflicts with application code.
The "implementation" is just a trivial wrapper around free. This could
eventually replaced by implementations that are more efficient than
that.
