As we use QAPI NetClientState->stored_config to store and get information
about backend network devices, we can drop fill of legacy field info_str
for them.
We still use info_str field for NIC and hubports, so we can not completely
remove it.

The info_str field of the NetClientState structure is static and has a size
of 256 bytes. This amount is often unclaimed, and the field itself is used
exclusively for HMP "info network".
The patch translates info_str to dynamic memory allocation.
This action is also allows us to painlessly discard usage of this field
for backend devices.

The query-netdev command is used to get the configuration of the current
network device backends (netdevs).
This is the QMP analog of the HMP command "info network" but only for
netdevs (i.e. excluding NIC and hubports).
The query-netdev command returns an array of objects of the NetdevInfo
type, which are an extension of Netdev type. It means that response can
be used for netdev-add after small modification. This can be useful for
recreate the same netdev configuration.
Information about the network device is filled in when it is created or
modified and is available through the NetClientState->stored_config.

Vendor driver may not support or implement config
interrupt delivery for link status notifications.
In this event, vendor driver is expected to NACK
the feature, but guest will keep link always up.

We want to introduce a new version of qemu_open() that uses an Error
object for reporting problems and make this it the preferred interface.
Rename the existing method to release the namespace for the new impl.
