This patch adds a wrapping functionality to imag-log.
The commandline parameter `-w` or `--wrap` can not be used to wrap the
output at N characters, defaulting to 80 characters.

This patch removes the magic constant we used when calling
`trace_unwrap_exit()` or `map_err_trace_exit_unwrap()`.
We used to call it with `1` as parameter, where the number was the exit
code to use. Now the implementation of the function does it
automatically (using 1 (one) as exit code).
All calls of these functions were fixed. Thanks to vim this was easy.

Because this API only errors when write!() errors occur, we can return
the exit code as an error here.
This way the user of the API can immediately exit if there was an IO
error, but the API automatically takes care of the right return value,
returning (exiting) with zero (0) if there was an "Broken pipe" error
and with one (1) otherwise, which is the expected behaviour here.
All calls to that API were changed accordingly.

The problem was that the used `Diary::diary_names()` iterator does not
call `unique()` on its output.
That decision was made because the return type would get more
complicated with that feature.
Now that rustc 1.26 with Impl Trait is out, we can refactor the return
types of these functions (so also with `Diary::diary_names()`) to
automatically do this.
