+Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
+write handlers no longer carries a 'last' parameter. This will make
+yaz_iconv flush "less" characters. A flush is performed by call to
+yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
+
+Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
+removed, because function yaz_query_to_wrbuf does the same.
+
+API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
+wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
+
+Deprecated MARC utility functions removed.
+
+Changed prototype of yaz_marc_decode_buf: const char for result and size_t
+for rsize.

connections that are in asynchronous mode.
