92b54d6490 Add heuristic when rewriting chain with a single child
rustfmt splits chain into multiline when the length of chain exceeds
`chain_one_line_max`. However, currenly this rule only applies when the chain
has more than one child. This can lead to unexpected long chain if the parent
is long. This commit adds heuristic that if the length of parent is longer
than the half of `chain_one_line_max` we use multiline even if there is
only a single child.

c0bdbfa531 Switch to accessing config items via method.
Preparation for #865, which proposes adding a flag which outputs which
config options are used during formatting.

This PR should not make any difference to functionality. A lot of this
was search-and-replace.

Some areas worthy of review/discussion:

 - The method for each config item returns a clone of the underlying
   value. We can't simply return an immutable reference, as lots of
   places in the code expect to be able to pass the returned value as
   `bool` (not `&bool). It would be nice if the `bool` items could
   return a copy, but the more complex types a borrowed reference... but
   unfortunately, I couldn't get the macro to do this.
 - A few places (mostly tests and `src/bin/rustfmt.rs`) were overriding
   config items by modifying the fields of the `Config` struct directly.
   They now use the existing `override_value()` method, which has been
   modified to return a `Result` for use by `src/bin/rustfmt.rs`. This
   benefits of this are that the complex `file_lines` and `write_mode`
   strings are now parsed in one place (`Config.override_value`) instead
   of multiple. The disadvantages are that it moves the compile-time
   checks for config names to become run-time checks.
