[PATCH v3 0/6] Add vmnet.framework based network backend |

macOS provides networking API for VMs called vmnet.framework.
I tried to add it as a network backend. All three modes are supported:
-shared:
allows the guest to communicate with other guests in shared mode and
also with external network (Internet) via NAT
-host:
allows the guest to communicate with other guests in host mode
-bridged:
bridges the guest with a physical network interface
Separate netdev for each vmnet mode was created because they use quite
different settings, especially since macOS 11.0 when vmnet.framework
gets a lot of updates.
Not sure that I use qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread() in correct way while sending packet
from vmnet interface to QEMU. I'll be happy to receive
recommendations how to make this thing better if I done sth wrong.
Also vmnet.framework requires com.apple.vm.networking entitlement to
run without root privileges. Ad-hoc signing does not fit there,
so I didn't touch anything related to signing. As a result we should
run qemu-system by a privileged user:
`$ sudo qemu-system-x86_64 -nic vmnet-shared`
otherwise vmnet fails with 'general failure'.
But in any way it seems working now,
I tested it within qemu-system-x86-64 on macOS 10.15.7 host, with nic
models:
- e1000-82545em
- virtio-net-pci
and having such guests:
- macOS 10.15.7
- Ubuntu Bionic (server cloudimg)
v1 -> v2:
Since v1 minor typos were fixed, patches rebased onto latest master, redundant
changes removed (small commits squashed)
v2 -> v3:
- QAPI style fixes
- Typos fixes in comments
- `#include`'s updated to be in sync with recent master
