dhclient: Fix the trivial buffer overruns correctly
A DHCP client identifier is simply the hardware type (one byte) concatenated
with the hardware address (some variable number of bytes, but at most 16).
Limit the size of the temporary buffer to match and the rest of the
calculations shake out correctly.
This is a follow-up to the incorrect r299512, reverted in r300172.

It broke client identifiers because I misunderstood the intent of the code.
There is still a minor issue detected by Coverity (at least, I can't find where
the code proves it isn't an issue). I'll follow up with a better fix for the

If a local (AF_LOCAL, AF_UNIX) socket creation (bind) is attempted

possible to make this work correctly, this patch avoids the crash
in the meantime.

a lot of sense when it returns an error for the others.

Rather than having the if_vmove() code intermixed in the vnet_destroy()
function in vnet.c move it to if.c where it logically belongs and put
it under a VNET_SYSUNINIT() call.
To not change the current behaviour make sure it runs first thing
during teardown. In the future this will allow us more flexibility
on changing the order on when we want to get rid of interfaces.
Stop exporting if_vmove() and make it file static.

zfsctl_freebsd_root_lookup: gfs_vop_lookup may return a doomed vnode
gfs code is (almsot) completely agnostic of FreeBSD VFS locking, so it
does not handle doomed but not yet dead vnodes and may return them.
Check for those vnodes here and retry a lookup.
Note that ZFS and gfs have additional protections that ensure that a
parent vnode of the current vnode is never doomed.
The fixed problem is an occasional failure to lookup a 'snapshot' or
'shares' directories under .zfs.
Note that for the above reason all uses of zfsctl_root_lookup() are
better be replaced with VOP_LOOKUP.
