0e29379bcf vmm: Make gdb break/resuming more resilient 
When starting the VM such that it is already on a breakpoint (via
stop_on_boot) when attached to gdb then start the vCPUs in a paused
state rather than starting the vCPUs later (upon resume).

Further, make the resumption/break of the VM more resilient by only
attempting to resume the vCPUs if were are already in a break point and
only attempting to pause/break if we were already running.

Fixes: #4354

Breaks the receive loop of the API client when the VMM shuts down the
socket connection. A shutdown is indicated by the return value 0 of the
`recv()` system call.[^1][^2] This case was not handled before, so the
API client tried infinitely to receive more bytes and did not return.

5f98710471 virtio-devices: vhost-user: Stop the vrings on a virtio reset

613c60fc6f virtio-devices: vhost-user: Enable correct queue indexes 
Rather than relying on the amount of queues to enable or disable the
queue that have been activated, we rely on the actual queue indexes
provided through the tuple including the queue index, the Queue and the
EventFd. By storing the list of indexes, we simplify the code and also
make it more accurate in case some queues aren't activated.

3f62a172b2 virtio-devices: Pass a list of tuples for virtqueues 
Instead of passing separately a list of Queues and the equivalent list
of EventFds, we consolidate these two through a tuple along with the
queue index.

The queue index can be very useful if looking for the actual index
related to the queue, no matter if other queues have been enabled or
not.

It's also convenient to have the EventFd associated with the Queue so
that we don't have to carry two lists with the same amount of items.
