v5.30.0

Extend the record conversion routines to handle OPAC encoding
with outputcharset and leaderspec. Example rule:

  <retrieval syntax="opac" name="OP2">
   <backend syntax="opac" name="F">
      <marc leaderspec="9=' '" inputformat="marc" outputformat="marcxml"
     inputcharset="utf-8" outputcharset="marc-8"/>
   </backend>
 </retrieval>

For this to work yaz_record_get_output_charset is defined. YAZ-927
