* Fix use-after-free for repeated fetchrow_arrayref calls when
  mysql_server_prepare=1

  Function dbd_st_fetch() via Renew() can reallocate output buffer for
  mysql_stmt_fetch() call. But it does not update pointer to that buffer in
  imp_sth->stmt structure initialized by mysql_stmt_bind_result() function.
  That leads to use-after-free in any mysql function which access
  imp_sth->stmt structure (e.g. mysql_stmt_fetch()).

  This patch fix this problem and properly updates pointer in imp_sth->stmt
  structure after Renew() call.
  This is a medium level security issue to which the Debian security team
  assigned identifier CVE-2016-1251. Discovered and fixed by Pali Rohár.

* auto_reconnect now also matches  CR_SERVER_LOST, previously this only
  matched CR_SERVER_GONE.

* Fix compilation fixes (Pali Rohár).
