Subject: API Improvements     - Removed 'rlen' return parameters there not
 necessary for multibyte encodings     - Two versions of recode functions:
 rccRecode -> rccRecode, rccSizedRecode     - Class Types: CONST,
 SKIP_SAVELOAD     - New recode functions: rccToCharset, rccFromCharset     -
 More new recode functions: rccRecodeToCharset, rccRecodeFromCharset,
 rccRecodeCharsets     - New function: rccGetCompiledConfiguration     - All
 warnings are fixed     - Perform "File Name" search only if there are non
 ISO8859-1 chars in the name.     - Do not copy invalid characters, - skip
 them.     - Fixed error in rccRecode with 'Recoding Cache' switched On.     -
 Strip leading and trailing spaces in rccDB4 get/set
