Thats fine - You need to create the patch again, there were a lot of conflicts
with 691.

"ROW FORMAT BINARY" is just a shortcut to "ROW FORMAT SERDE ...".
This shortcut will help the adoption of this serde for tables created by users,
and users will enjoy the performance benefit of this over the default
LazySimpleSerDe.
We can have more binary representations in future, but they will need a
different shortcut (if a shortcut is needed).

Instead of supporting:
CREATE TABLE xxx (...)
ROW FORMAT BINARY
STORED AS SEQUENCEFILE;
shouldn't we let the user specify the serde
CREATE TABLE xxx (...)
ROW FORMAT SERDE '';
I mean the existing syntax.
If we have more binary representations in future, how will we address that ?
