6d1077fc3c vmm: Unix socket backend for serial port
Cloud-Hypervisor takes a path for Unix socket, where it will listen
on. Users can connect to the other end of the socket and access serial
port on the guest.

    "--serial socket=/path/to/socket" is the cmdline option to pass to
cloud-hypervisor.

Users can use socat like below to access guest's serial port once the
guest starts to boot:

    socat -,crnl UNIX-CONNECT:/path/to/socket

f346687e3d vmm: default GDB to false when deserializing
This fixes the valid VM config unit tests, which would otherwise fail
to deserialize their expected JSON config due to the missing "gdb" field.

e3d2917d5f vmm: Implement Clone and Drop for VmConfig
The custom 'clone' duplicates 'preserved_fds' so that the validation
logic can be safely carried out on the clone of the VmConfig.

The custom 'drop' ensures 'preserved_fds' are safely closed when the
holding VmConfig instance is destroyed.

a84b540b65 vmm: config: Extend 'VmConfig' with 'preserved_fds'
Preserved FDs are the ones that share the same life-time as its holding
VmConfig instance, such as FDs for creating TAP devices.

Preserved FDs will stay open as long as the holding VmConfig instance is
valid, and will be closed when the holding VmConfig instance is destroyed.

ea4a95c4f6 vmm: config: Implement Clone for NetConfig
The custom version duplicates any FDs that have been provided so that
the validation logic used on hotplug, which takes a clone of the config,
can be safely carried out.

7ad58457b0 vmm: Split structs from logic that make up VmConfig
Place the data structures that are required for constructing a VmConfig
into it's own module from the logic that exists to suppot them.

This is useful as a consumer of the API can now clearly see what data
structures make up the API for creating VMs.

This has no functional change and I made no attempt to clean up the
ordering (it's as in the original file) nor any other clean up.
