In this patch although tables are passed individually, the ctx parameter is
still kept for most functions. With ctx, it is still easy for the function
to access any tables than the individual tables passed.
I see two reasons why ctx is still kept in this patch:
1) index implementation requires passing the IDL, and I saw this is
addressed in next patches by redesigning the index mechanism
2) OVSDB transaction requires passing the ..._idl_txn in the ctx. I think
we can pass in ..._idl_txn directly instead of the ctx. This would avoid
the misuse of tables.
What do you think about point 2)?
