Cleanup: update f_memory function structure to follow more recent practices.

Cleanup: update f_memory function structure to follow more recent practices.

The more recent practices being followed are having constants on the left and pointers on the right.

The f_memory functions appear to be well followed and the update to this turned out pretty easy.
Despite how many things depend on memory operations in this project, there is actually very little to change.
I consider this a small victory in how my project is designed and intended to be used.
