Feature: Add f_abstruse project.

This is the initial design and may be subject to significant change as I begin to use it more.

The idea here is to provide a type that can act as a catch all for any sort of header of any specific type.
I use standard types and provide void pointer types for everything else.

I have some concerns about supporting void pointer types due to the special case of how to handle this allocation actions.
I have decided to withhold the "append" and similar standard functions for now until I get a better grasp on how this should be used.

A union is used to use the same memory space at the cost of the largest size.

A dynamic string is likely the most common case.

The resize and similar functions provide warnings that the caller needs to be careful about allocation and de-allocation.
This poses extra security concerns for when callers of these functions do not properly or safely handle the data.

I intend to use this in the FSS Simple Packet processing code, such as writing (building) the Simple Packet string.
