Implement an enhanced version of MASM's dup() and "db ?" syntax. Add support for complex data (Dx) statement expressions involving both initialized and uninitialized data. In addition, we have support for overriding the size of each element on an individual item and/or list basis. Signed-off-by: H.

listing: list short reserved blocks as ?? instead of <res ...> <res ...> can get rather annoying when mixed in with data, as can happen with the MASM-like db syntax. List shorter blocks (8 bytes or less) as ?? instead; 8 bytes avoids line breaks for a single statement. This is probably more readable anyway... Signed-off-by: H.
