Maybe fopen() should be implemented using fdopen()? It does the same thing but additionally calls the 'open' syscall to get a file descriptor to a file.

----------------
should be in posix.td


This is a draft/work-in-progress. Probably needs some tests, and the
entry in libc/config is just an example here. Should also be added to
other arches.

Did this to get a little more comfortable with how llvm libc works,
comments are very welcome.
