This change breaks the IDL into two layers: the IDL proper, whose
interface to its client is unchanged, and a low-level library called
the OVSDB "client synchronization" (CS) library. There are two
reasons for this change. First, the IDL is big and complicated and
I think that this change factors out some of that complication into
a simpler lower layer. Second, the OVN northd implementation based
on DDlog can benefit from the client synchronization library even
though it would actually be made increasingly complicated by the IDL.

This new module has a single direct user now. In the future, it
will also be used by OVN.
