Revert "Added what I call virtual io to tinycc this way we can make a monolitic executable or library that contains all needed to compile programs, truly tinycc portable."

This reverts commit 59e18aee0e509a3ca75dbe6f909e18c1d17893d1.
tcc is being stabilized now in order to do a new release soon.
Therefore, such a change is not appropriate now.
