removed function definitions and opted for using macros instead.
It now does not have a set limit when it comes to printing (at least,
it's the stdc's limit again). However, it is now no longer possible to
use a character pointer to print information to the screen.
__FILE_NAME__ and GLFW_CONTEXT_DEBUG were causing problems in the CI
pipeline, thus I deemed them unreliable.
__FILE_NAME__ is not __FILE__ which is more universally used across
compilers.
and GLFW_CONTEXT_DEBUG has been replaced with GLFW_OPENGL_DEBUG_CONTEXT,
which is a legacy definition, which plays nicer on older platforms.
(like ubuntu)
