missing altar drop messages

Most callers of dropx did not check for altars, but should have.  Rather
than add such checks, I moved the check from drop to dropx.  I also found
several callers of dropx that could generate out-of-order messages for some
cases (not new) and fixed them. FYI - callers of dropy don't seem to want
altar checks or already do them.
