Fixed problems:
- All the modules are linked against libiconv. iconv() now can be
called from other shared libraries (it could only be called from
executables in iconv-1.0);
- Case insensitive recognition of charset names. There was a bug in
1.0: the first letter of a charset name was case sensitive;
- Modified behaviour of iconv() used with (inbytesleft == NULL) or
(*inbytesleft = 0): now iconv silently returns 0; in 1.0 it
returned (size_t)(-1) and set errno=EINVAL. According to POSIX
specification both ways are correct; the new behaviour is just
less restrictive.
