Wrote my AIO

POSIX asynchronous I/O is very sub-optimal. They create threads, dynamically allocate memory, and invoke a lot of system calls (which set the signal mask, priority, and more). Additional locks are also possible (if the AIO is using someone else). Moreover, they are not portable.

Rewritten file I / O for portable C API

Apart from portability, it also provides more guarantees (for example, the write system call does not guarantee that the entire buffer will be written, unlike fwrite, which guarantees that the entire buffer will be written without errors).
