svnrdump: dump_editor: Use just one temporary file for all textdelta
application by truncating and re-using it in each iteration. This has
significant performance benefits.
(dump_edit_baton): Correct the comment about the description of
pool, add a new delta_file variable and note in a comment that
delta_file and delta_abspath should be allocated in the
per-edit-session pool, not in the per-revision pool like the other
(get_dump_editor): Open the delta file initializing `eb->delta_file`
and `eb->delta_abspath`, allocating them in the per-edit-session
pool. Mark delta_file as a del_on_close, so that it's automatically
cleaned up when the editor is done. All streams in callbacks that
map to it should set disown = TRUE.
(close_file): Instead of opening the delta_file, simply seek to the
beginning. During cleanup, don't close or remove the file; just
truncate it to get it ready for the next textdelta
application. Also, while getting the file stat, don't re-open the
file -- use apr_file_info_get on the open file instead.
(apply_textdelta): Don't create a unique file. Simply map a stream
to the delta file to perform the textdelta application. Disown the
stream and close it explicitly, making sure not to close the delta
