Perform a global baton variable rename in the diff editor. Rename all local variables pointing to an editor_baton to eb, to a directory_baton db, and fb for file_batons. This matches the style of the other editors in libsvn_wc.
Perform a global baton variable rename in the diff editor. Rename all
local variables pointing to an editor_baton to eb, to a directory_baton
db, and fb for file_batons. This matches the style of the other editors
in libsvn_wc.

Use the local eb variable, where the edit_baton was alread locally
cached and update whitespace to match the current conventions.

No functional changes at all.
(I left a few incorrectly spaced svn_wc__adm_abspath() calls that will
be updated to baton references in the next patch)

  (dir_baton): Rename dir_baton variable to parent_baton and
    edit_baton to eb.
