Use imsg_get_fd() in vmd. vmd uses a lot of fd passing and does it sometimes via extra abstraction so this just tries to convert the code without any optimisations. ok dv@

vmd(8): pull validation into local prefix parser. Validation for local prefixes, both inet and inet6, was scattered around. To make it even more confusing, vmd was using generic address parsing logic from prior network daemons. vmd doesn't need to parse addresses other than when parsing the local prefix settings in vm.conf and no runtime parsing is needed. This change merges parsing and validation based on vmd's specific needs for local prefixes (e.g. reserving enough bits for vm id and network interface id encoding in an ipv4 address). In addition, it simplifies the struct from a generic address struct to one focused on just storing the v4 and v6 prefixes and masks. This cleans up an unused TAILQ struct member that isn't used by vmd and was leftover copy-pasta from those prior daemons. The address parsing that vmd uses is also updated to using the latest logic in bgpd(8). ok mlarkin@

Propagate host-side tap(4) lladdr to guest vm process to allow unicast dhcp and bootp renewals with vmd(8)'s built-in dhcp server. Previous behavior ignored did not intercept these packets and instead transmitted them. This should make vmd(8)'s dhcp behave more as a true dhcp server should and allows it to work properly with the new dhcpleased(8) attempting a renewal. OK mlarkin@

When system calls indicate an error they return -1, not some arbitrary value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

Add support for dynamic "NAT" interfaces (-L/local interface). When a local interface is configured, vmd configures a /31 address on the tap(4) interface of the host and provides another IP in the same subnet via DHCP (BOOTP) to the VM. vmd runs an internal BOOTP server that replies with IP, gateway, and DNS addresses to the VM. The built-in server only ever responds to the VM on the inside and cannot leak its DHCP responses to the outside. Thanks to Uwe Werler, Josh Grosse, and some others for testing! OK deraadt@

Add a new "priv" process that is responsible for ioctls and restricted operations that aren't allowed under pledge. This is a companion to the "vmd" process that runs as root but with pledge. With the "priv" process, each new tap(4) interface now gets a description to indicate the vm, eg. "vm1-if0-myvm". For network configuration will be done by vmd/priv later. OK mlarkin@
