Redefine _IO_iconv_t to store a single gconv step pointer [BZ #25097]
libio can only deal with gconv conversions which consist of a single
step. Not using __gconv_info simplifies the data structures somewhat.
This eliminates a new GCC 10 warning about subscribing an inner
zero-length array.
Tested on x86_64-linux-gnu with mainline GCC. Built with
build-many-glibcs.py, also with mainline GCC. Due to GCC PR 92039,
there are failures left on 32-bit architectures with float128 support.
