Feature: provide common string related memory increment functions.

There are a lot of string functions.
In this case, it seems worth more to use functions instead of relying on macros, given how common this is.

This does not update most of the existing code that may want to use this.
Future consideration will likely be made in regards to the array of array string types.

There is no intention to expand this process to other types.
