Remove a bunch of useless lib/common.asm functions

These were legacy from a previous tutorial I was based on once upon a time.

Now all libs (x86-64) only have a minimum set of functions, basically to support ASSERT_FAIL.

All the rest was for visibility and can be done more easily with GDB... I was such a newb :-)

Some of the removed functionality was for portability with 50 Windows assemblers,
but since I don't feel like porting properly, and no one will ever send pull requests,
I'm just removing that untested stuff for now.
