dlclose

elfload_dlclose is completely unimplemented. This is unsurprising when you realize that the structure that holds the elf files that have been loaded is a simple pre-allocated array, which means that closing a file opened somewhere in the middle in the array would leave that remnent unusable unless changes are made to the structure.

Similarly, there needs to be a way to close files, period.

I like the simplicity of the array, but perhaps it's too simple? :/
