2023-02-17vmnet: stop recieving events when VM is stoppedJoelle van Dyne1-13/+35
When the VM is stopped using the HMP command "stop", soon the handler will stop reading from the vmnet interface. This causes a flood of `VMNET_INTERFACE_PACKETS_AVAILABLE` events to arrive and puts the host CPU at 100%. We fix this by removing the event handler from vmnet when the VM is no longer in a running state and restore it when we return to a running state.

Interaction with vmnet.framework in different modes differs only on configuration stage, so we can create common `send`, `receive`, etc. procedures and reuse them.
