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

686e6d5082 api-client: Break the receive loop if the VMM shuts down the socket 
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.
