This will become the public interface for implementing
bdev modules. Right now the file exposes too much of
the guts of the bdev layer to modules, so it needs
to be stripped down.

The hot remove callback is registered when we open the bdev in the
examine callback, but it's not used just during examine; change the name
of the callback to more accurately reflect what it is for.

Add state_mask to each RPC method and state to RPC server, respectively.
State mask of RPC method is set at registration. State of RPC server
is changed according to the state of the SPDK.
When any RPC method is recieved, if the bit of the RPC server is on in
the state mask of the RPC method, it is allowed. Otherwise, it is
rejected.
When any RPC is rejected by state_mask control, the new error code
is returned to describe the error clearly.

The patch here is to have two utility functions that can be
called in the examine path and also through the newly created
create_passthru_disk() public function.
This is also a preparation work to add the RPC method to construct
the passthru vbdev at runtime.
