    Drop unfinished support for binary & before/after diffs from VcsDiff · 36fd6bf0

    VcsDiff and IBasicVersionControl::diff(...) many years ago got initial
    support for requesting and storing raw copies of files changed in a
    Nothing in KDevelop though makes use of that feature, and all the VCS
    plugins themselves do not support it either, even ignore explicit requests.
    To ease maintainance of the used and working code for creating unified
    text diffs, this patch drops the dead code for that unfinished feature.
    When someone ever starts working on it again, the needed structures
    in VcsDiff can be easily readded and also done matching whatever approach
    is taken then.
    After the initial support was introduced in 2007 by e.g. commits
    5ffc3c23 and 7b09fc2f
    no further related work was ever commited to the codebase.
    SvnDiffJob even has initial code for fetching full before-versions of
    the affected files. But this seems premature test code which accidentally
    got committed, as the full copies are always fetched and stored
    additionally to the unified diff, and without respecting the diff type
    parameter passed to the method. Also were the after-versions not stored,
    and no other code also has ever been fetching those full copies
    from the returned VcsDiff object.
    Worse, most other VCS plugins simply ignored the diff type parameter passed
    to the IBasicVersionControl::diff(...) method, and always returned a
    unified diff, rendering the type parameter useless.
