net: use Netdev instead of NetClientOptions in client init

Browse Source 
This way we no longer need NetClientOptions and can convert Netdev
into a flat union.

[rework net_client_init1() to pass Netdev by copying from NetdevLegacy,
rather than merging the two types - which means that we still need
NetClientOptions after all.  Rebase to qapi changes. The bulk of the
patch is mechanical, replacing 'opts' by 'netdev->opts', while
net_client_init1() takes care of converting between legacy and modern
types.]
