Re: [PATCH] Fix for "\r" in "svnrdump load" (issue 4263) (reworked)

[[[
Fix issue #4263: svnrdump: E125005: Cannot accept non-LF line endings in
'svn:log' property

Fix to ensure that no "\r" characters are present in revision or node
props.

In the case of "\r\n" character sequences, the "\r" is removed.

In the case of "\r" characters which are not followed by "\n", the "\r"
is replaced by a "\n" character.

* subversion/svnrdump/svnrdump.h:
    (svn_rdump__normalize_prop): New function declaration.

* subversion/svnrdump/util.c:
    (svn_rdump__normalize_prop): New function to allow "svnrdump load" to
      use existing logic
    (svn_rdump__normalize_props): Refactored to move logic into
      svn_rdump__normalize_prop()

* subversion/svnrdump/load_editor.c:
    (set_revision_property): Added call to svn_rdump__normalize_prop()
    (set_node_property): Added call to svn_rdump__normalize_prop()

* subversion/tests/cmdline/svnrdump_tests.py:
    (copy_bad_line_endings_load): Removed "XFail" decorator
