  -----------
  [libc] refactor printf file writing

Add return values to converter functions to allow for better error
handling when writing files. Also move the file writing code around to
be easier to read.

  -----------
  [libc] add printf

This patch adds the entrypoint for printf. With this, building a
"hello world" program with just LLVM-libc is possible.
