cli: 'restart' should close open files (VPP-1068)
- On 'restart' close all registered files (except stdio) so that the
new process has a clean start; in particular, CLI sockets, API
sockets, tun/af_packet etc descriptors all need to close so they're
not left open but unused by the new VPP process. To do this we iterate
all the files registered for the polling mechanism and close() them.[1]
- While we're here, retain the original environment on 'restart';
several things make use of it.
[1] An alternative mechanism would be to mark all files with CLOEXEC
on opening; I think that is a little fragile for this fairly esoteric
use case.
