[in subversion/tests/cmdline]

* merge_tests.py (merge_conflict_markers_matching_eol,
                  merge_eolstyle_handling),
* patch_tests.py (patch_no_svn_eol_style,
                  patch_with_svn_eol_style,
                  patch_with_svn_eol_style_uncommitted),
* update_tests.py (conflict_markers_matching_eol,
                   update_eol_style_handling):
  Specify keep_eol_style = True evne if platform is Windows.

* merge_tests.py (merge_conflict_markers_matching_eol),
* patch_tests.py (patch_no_svn_eol_style,
                  patch_with_svn_eol_style,
                  patch_with_svn_eol_style_uncommitted),
* update_tests.py (conflict_markers_matching_eol):
  Use binary mode to write file contents for strict eol style.

* merge_tests.py (merge_conflict_markers_matching_eol),
* patch_tests.py (patch_with_svn_eol_style,
                  patch_with_svn_eol_style_uncommitted),
* conflict_markers_matching_eol):
  Switch per platform eol value for 'native' svn:eol-style

* svntest/wc.py (State.from_wc):
  Use io.open() explicitly to specify 'newline' parameter for universal
  newline, even on Python 2.  With this change, '\r' end of line chracters in
  files are also translated to '\n' if keep_eol_style=False (or unspicified)
  on Python 2.  Also explicitly specify encoding to 'utf-8' not to be affected
  by Python's file system encoding.
