Wolfgang Bumiller 4d0ea9978b getopt: let parse_arguments() take a slice of AsRef<str>
We don't need the content to be owned strings, and we don't
need the list to be a Vec, since we only care about being
able to iterate through and copy out portions of the strings
we need, so take an &[T] where T: AsRef<str>.

This avoids .iter().map(to_string).collect() before calling
parse_arguments().

Wolfgang Bumiller 2482c095b1 getopt: remove skip logic
The 'skip' variable was set to indicate that the "rest of
the args" is to be copied into the 'rest' vec. We can do
this directly and avoid the 'if' case in the loop
altogether.

Wolfgang Bumiller ad8a98f7e4 parse_arguments: work with utf8 bytes and reduce indentation
We are only caring about '=' and '-' which are single-byte
codepoints, so there's no reason not to work on a byte
slice.

Also, some indentation reduction:

Transform
    if (a) {
        ...
        return A;
    }
    return B;
into
    if (!a)
        return B;
    return A;

and
    if (a)
        if (b)
            foo()
into
    if (a && b)
        return;

* add lock_file as a function working on already-opened
  files
