If io::with_str_writer was pure, it could then be used safely with to_str::ToStr.

And with this, we should also make these similar functions pure:

io::with_bytes_reader
io::with_bytes_writer
io::with_str_reader

Auto merge of rust-lang#3769 - primoly:miri-start, r=RalfJung
5852b24 
Add `miri_start` support

This PR uses a function with the exported symbol `miri_start` as a drop-in alternative to `#[start]`. So the signature stays the same as suggested in [this comment](rust-lang/miri#3498 (comment)). <del>I’ve also removed Miri’s restriction  to only work on bin crates as I don’t think this is necessary anymore.</del>

Closes rust-lang#3758
