Graeme Hewson noted that zlib has a bug wherein "gzseek()" doesn't set
the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.
To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.
