## Description of change
Add tunnelhost/tunnelclient modes to -nicspoof so two cabs can do
LAN-style BPL matching over a real UDP path (including Wine), while
keeping the fake overlay NIC. Offline spoof remains available as before.

## Description of change
Add `-icmphook` option under spicecfg Development/Network for emulating
keepalive ping replies in user mode, so games do not need to open
privileged raw ICMP sockets. This makes connecting to networks possible
on macOS under Whisky, and on Windows with ICMP firewalled or spice
running without Administrator privileges.
## Testing
Tested DDR and SDVX on Windows 10 and macOS Tahoe. Network check status
in test menu shows `CONNECTED` when -icmphook is enabled, and `NOT
CONNECTED` when it is disabled. Actual network functionality works as
expected (under previously impossible conditions).
