Rewriting the C functions listed below in x86-64 assembly using NASM to create a static
library (libasm.a). Tests for these functions are provided in C (main.c),
as well as in assembly (main.s).
The mandatory directory contains basic string functions (completed), while the bonus section includes linked list functions (WIP).
Since some rewritten functions use system calls and may call ___errno_location,
it is possible to check the type of error (e.g., Bad file descriptor, Bad address).
As a result, perror() will return or print an appropriate error message.
