Subject: Remove the Result typedef

Many of our functions do not return a Result<_, Error>, but for example
a Result<_, (Device, Error)>.  We only use the typedef in one function,
but it makes the other functions more complicated as we have to use
result::Result (if crate::Result is imported).  Therefore, this patch
removes the typedef.  Applications or libraries can still redefine it if
they want to.
