Alan Donovan 60ddccae85 internal/diff: Apply: validate inputs
Apply now checks that its edits are valid
(not out of bounds or overlapping),
and reports an error if not.

It also sorts them, if necessary, using (start, end)
as the key, to ensure that insertions (end=start)
are ordered before deletions at the same point
(but without changing the relative order of insertions).

Two other implementations of the diff.Apply algorithm
have been eliminated. (One of them failed to sort edits,
requiring the protocol sender to do so; that burden
is now gone.)
