Merge branch 'rb/stdlib_re_unicode_fixes' into ccase/r13b04_dev

* rb/stdlib_re_unicode_fixes:
  Fix lost unicode option in re:compile()
  Refactor out repeated block in re module
  Fix re:replace/4 to handle unicode charlist Replacement argument
  Fix re:replace/4 to handle unicode charlist RE argument
  Fix re:replace/4 to handle binary unicode output when nothing replaced

OTP-8394  A number of bugs concerning re and unicode are corrected:
          - re:compile no longer loses unicode option, which also fixes bug
            in re:split.
          - re:replace now handles unicode charlist replacement argument
          - re:replace now handles unicode RE charlist argument correctly
          - re:replace now handles binary unicode output correctly when
          nothing is replaced.

          Most code, testcases and error isolation done by Rory Byrne.
