The only exposed symbol is now the ComputeEdits function, all other functionality
is now moved up to the diff layer and using edits instead of operations.

It is now in the diff package written in terms of edits, instead of the myers package.
This also means that the unified handling is no longer pluggable because it does
not need to be.

This makes it so the diff package is depended on by all implementations, rather
than the diff package having to depend on the default myers implementation.

We only need one implementation of this, it must cope with all inputs, and it
has no freedom in it's results, so it does not need to be pluggable.

This allows us to use the diff.ApplyEdits in tests, saving us from a different
implementation.
It also prepares for command lines that need to use diff features based on the
results of a protocol message.
Splitting content into lines is too easy to get wrong, and needs to be done
correctly or the diff results make no sense. This adds the SplitLines function
to the diff pacakge to do it right and then uses it everwhere we we already
doing it wrong.
It also makes all the diff tests external black box tests.

This adds unified diff handling to the diff package.
It also adds a lot more testing and also verifies the unified
diff tests against the diff program if you run the tests with
the flag -verify-diff
This functionality is needed for some of the command verbs.
