[Bug libc/4936] New: iconv(cd, 0, 0, 0, 0); doesn't behave like documented (glibc 2.5 and 2.6.1 atleast)

["stian at nixia dot no" <sourceware-bugzilla at sourceware dot org>]

According to the documentation, iconv(cd) with both inputbuffer and outputbuffer
set to NULL should reset the state of `cd`. However, this does not work for
"unicode" atleast.

A unicode stream starts with a BOM character, and after a iconv(cd, 0, 0, 0, 0),
I just get an error if I feed it with a new BOM character.

cd=iconv_open("utf-8", "unicode");
iconv(cd, unicode_string_with_bom, &srclen, &target, &targetlen); /* ok */
iconv(cd, 0, 0, 0, 0); /* this should reset the state of cd */
iconv(cd, unicode_string_with_bom, &srclen, &target, &targetlen); /* this now fails*
