Updated converters/p5-Text-Iconv to 1.7

1.5  Thu Aug 30 14:42:08 CEST 2007
- Various small changes to make Text::Iconv compile on OpenVMS
  (based on a patch by Peter (Stig) Edwards)
- Output buffer was always initialized to 5 bytes--this was
  just for testing, but I'd forgotten to revert back to the
  original code (detected via a bug report by Aldo LeTellier).

1.6  Sat Oct 13 00:16:30 CEST 2007
- Makefile.PL now uses File::Spec to portably specify the null
  device.  This should make it possible to build Text::Iconv
  on Windows "out of the box".
- Added get_attr() and set_attr() methods.  They provide an
  interface to the iconvctl() function of GNU libiconv.

1.7  Wed Oct 17 15:49:56 CEST 2007
- Makefile.PL now explicitly declares "use 5.006;" since it
  uses functionality like delete() for array elements.
- In Iconv.xs, moved the variable declarations in
  ti_set_attr() and ti_get_attr() into the PREINIT: section.
  This makes it possible to compile it using gcc 2.96.
