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.

Rather than replacing the whole file on gofmt or goimports, use the Myers
diff algorithm to compute diffs for a file. We send those back as text
edits.
