Arjun Shankar 91927b7c76 Rewrite iconv option parsing [BZ #19519]
This commit replaces string manipulation during `iconv_open' and iconv_prog
option parsing with a structured, flag based conversion specification.  In
doing so, it alters the internal `__gconv_open' interface and accordingly
adjusts its uses.

This change fixes several hangs in the iconv program and therefore includes
a new test to exercise iconv_prog options that originally led to these hangs.
It also includes a new regression test for option handling in the iconv
function.
