Re: iconv modules

[Bruno Haible]

Hi Simon,

> The interface sounds good to me, let's see the code. ;)

I'm making some changes to iconvme::iconv_string on the way of the merge.
I've put them on the 'haible-private' branch of lib/iconvme.c. All based
on code in use in GNU gettext for years. What do you think about them?
Acceptable?

revision 1.6.2.7
(iconv_alloc): Realloc the final result, to throw away unused memory.

revision 1.6.2.6
(iconv_alloc): Handle the IRIX iconv behaviour.

revision 1.6.2.5
(iconv_alloc): Call iconv with 2xNULL arguments, also to flush the state
storage.

revision 1.6.2.4
(iconv_alloc): Call iconv with 4xNULL arguments initially, to reset the state.

revision 1.6.2.3
(iconv_alloc): No need to test for " && dest " at the end - dest is
always != NULL there.

revision 1.6.2.2
(iconv_alloc): Don't assume that malloc() or realloc(), when failing, sets
errno to ENOMEM. (malloc on GNU/kFreeBSD doesn't.)

revision 1.6.2.1
(iconv_string): No need to save and restore errno when iconv_alloc succeeded.
