[RFC PATCH v2 0/8] qapi: net: add unix socket type support to netdev backend |

"-netdev socket" only supports inet sockets.
It's not a complex task to add support for unix sockets, but
the socket netdev parameters are not defined to manage well unix
socket parameters.
As discussed in:
"socket.c added support for unix domain socket datagram transport"
https://lore.kernel.org/qemu-devel/1C0E1BC5-904F-46B0-8044-68E43E67BE60@gmail.com/
This series adds support of unix socket type using SocketAddress QAPI structure.
Two new netdev backends, "stream" and "dgram" are added, that are barely a copy
of "socket"
backend but they use the SocketAddress QAPI to provide socket parameters.
And then they also implement unix sockets (TCP and UDP).
Some examples of CLI syntax:
for TCP:
-netdev stream,id=socket0,addr.type=inet,addr.host=localhost,addr.port=1234
-netdev
stream,id=socket0,server=off,addr.type=inet,addr.host=localhost,addr.port=1234
-netdev dgram,id=socket0,\
local.type=inet,local.host=localhost,local.port=1234,\
remote.type=inet,remote.host=localhost,remote.port=1235
for UNIX:
-netdev stream,id=socket0,addr.type=unix,addr.path=/tmp/qemu0
-netdev stream,id=socket0,server=off,addr.type=unix,addr.path=/tmp/qemu0
-netdev dgram,id=socket0,\
local.type=unix,local.path=/tmp/qemu0,\
remote.type=unix,remote.path=/tmp/qemu1
for FD:
-netdev stream,id=socket0,addr.type=fd,addr.str=4
-netdev stream,id=socket0,server=off,addr.type=fd,addr.str=5
-netdev dgram,id=socket0,local.type=fd,addr.str=4
v2:
- use "stream" and "dgram" rather than "socket-ng,mode=stream"
and ""socket-ng,mode=dgram"
- extract code to bypass qemu_opts_parse_noisily() to
a new patch
- do not ignore EINVAL (Stefano)
- fix "-net" option
