mod_real_query() is for binary data. and using MAX_QUERY_LENGTH will also pass
uninitialized buffer to mysql server which will result syntax error

so should pass there strlen(query) instead, but lets rather use mysql_query()
which will use \0 terminated string.

also the patch includes query into apache error log if the query failed.
