Hi,

I split the patches into 3 parts following David's suggestion. The first
patch removes the old FIXME by adding liba52 as inputs. The second patch
adds some configure flags. The third patch adds many new inputs.

Regarding Efraim's concern of closure size, the old closure size is
1459.3 MiB, the new closure size (without samba) is 1589.5 MiB and the
new closure size (with samba) is 1681.8 MiB.

Thanks,
Alex
