ctdb-common: Set immediate mode for pcap capture
Fix a problem where ctdb_killtcp (almost always) fails to capture
packets with --enable-pcap and libpcap ≥ 1.9.1. The problem is due to
a gradual change in libpcap semantics when using
pcap_get_selectable_fd(3PCAP) to get a file descriptor and then using
that file descriptor in non-blocking mode.
pcap_set_immediate_mode(3PCAP) says:
pcap_set_immediate_mode() sets whether immediate mode should be set
on a capture handle when the handle is activated. In immediate
mode, packets are always delivered as soon as they arrive, with no
buffering.
and
On Linux, with previous releases of libpcap, capture devices are
always in immediate mode; however, in 1.5.0 and later, they are, by
default, not in immediate mode, so if pcap_set_immediate_mode() is
available, it should be used.
However, it wasn't until libpcap commit 2ade7676101366983bd4f86bc039ffd25da8c126 (before libpcap 1.9.1) that
it became a requirement to use pcap_set_immediate_mode(), even with a
timeout of 0.

ctdb-common: Replace pcap_open_live() by lower level calls
A subsequent commit will insert an additional call before
pcap_activate().
This sequence of calls is taken from the source for pcap_open_live(),
so there should be no change in behaviour.
Given the defaults set by pcap_create_common(), it would be possible
to omit the calls to pcap_set_promisc() and pcap_set_timeout().
However, those defaults don't seem to be well documented, so continue
to explicitly set everything that was set before.

mdssvc: Do an early talloc_free() in _mdssvc_open()

When macOS Finder connect to a samba server with 'spotlight = yes',
macOS would issue mdssvc open (mdssvc.opnum == 0) to samba and it goes
