This commit adds a type to represent lines in files, and adds it to the
`Config` struct. It will be used for restricting formatting to specific
lines.

* Handle pub(restricted)
This commit properly handles pub(restricted) as introduced in RFC 1422
[0]. The syntax support was added in #971, but they were not correctly
formatted.

* Drop #[inline] attribute on format_visibility
* Make newly non-failing functions return String
The change to `format_visibiilty` means that `format_header` and
`format_unit_struct` can no longer fail. Their return type is updated to
reflect that.
The old behaviour stored everything in memory until we were finished. Now we write as soon as we can.
This gives better behaviour when formatting large programs, since there is some progress indication. It also opens the door to optimising memory use by not storing everything in memory unless it is required (which it still might be). That is left as future work though.
Most of the churn on this bump comes from the `Visibility` enum changing
from
pub enum Visibility {
Public,
Inherited,
}
to
pub enum Visibility {
Public,
Crate,
Restricted { path: P<Path>, id: NodeId },
Inherited,
}
which require taking `Visibility` by reference in most places. The new
variants are not handled at this point.

Do this so you can reliably build `rustfmt` in the future, even if one of the
dependencies (in this case, only `strings.rs`) makes backward-incompatible
changes.
