Motivation
This is the first task of BP-47
Provide an interface to the POSIX IO API + extensions for O_DIRECT and Linux's fallocate API in order to support direct IO on supported systems. Direct IO will allow us to bypass cache layers in the underlying operation system, improving memory usage and reducing unnecessary I/O operations to fill caches that won't be used.
