assumption (for standard c++ modules) about module interface. The module

[libc] add scanf entrypoints

This patch adds scanf, sscanf, and fscanf entrypoints. It also adds unit
tests for sscanf and a basic test to fscanf. The scanf function is
basically impossible to test in an automated fashion due to it recieving
user input.
