Errors logged when testing statd-callout don't currently go anywhere.
This is because arguments to the hacked version of script_log() are
ignored.
Remove the hack and configure logging to stderr.
This could go in the local statd-callout.sh setup script. However,
make it available for other script tests.

NOTICE level debug messages in common/run_event.c are not logged by
default.
Currently eventd ends up using ERROR, since this is specified as
LOGGING_LOG_LEVEL_DEFAULT. It doesn't inherit the debug level from
ctdbd and only uses NOTICE level when interactive.
Change the real logging default to NOTICE and use it everywhere.
Followups might be:
* Remove the default_log_level argument to logging_conf_init()
* Kick eventd to update debug level when "ctdb setdebug" is used

When testparm processes the output of "testparm -v" (which includes
default values) it appears to do global checks (or some other sort of
initialisation logic) for all specified values. This includes a DNS
lookup for the node's hostname, as a side-effect of a libldap
ldap_set_option() call when processing "ldap debug level". If DNS
servers are down then this can induce timeouts, possibly resulting in
monitor timeouts.
Avoid this by using sed to extract configuration values from the
testparm cache file.
This is already shown to work when retrieving share paths, where
testparm is basically used as cat. Update the sed pattern to avoid
matching empty values on the right-hand side of the equals ('=') -
this avoids the default empty path value (and "smb ports" never has an
empty value).
Corresponding test changes:
* 50.samba.monitor.111.sh no longer expects a failure from being
unable to set smb ports, since testparm is no longer used in that
code path.
* smb ports needs to be set in fake smb.conf so it is in the default
output and can be extracted using sed.
* Although testparm --parameter-name is no longer used in
50.samba.script, update the stub implementation (in case it is ever
used again) to extract from fake smb.conf, since "smb ports" is now
set there. The change from $parameter to $param allows a long line
to stay below 80 columns.

This happens because run_proc_context_destructor() directly does a
talloc_free() on the struct proc_context's and not the enclosing
tevent_req's. run_proc_kill() makes sure that we don't follow
proc->req, but it forgets the "state->proc", which is free()'ed, but
later dereferenced in run_proc_state_destructor().
This is an attempt at a quick fix, I believe we should convert
run_proc_context->plist into an array of tevent_req's, so that we can
properly TALLOC_FREE() according to the "natural" hierarchy and not
just pull an arbitrary thread out of that heap.

This uses Linux cooked capture link-layer headers. See:
https://www.tcpdump.org/linktypes/LINKTYPE_LINUX_SLL.htmlhttps://www.tcpdump.org/linktypes/LINKTYPE_LINUX_SLL2.html
The header type needs to be checked to ensure the protocol
type (i.e. ether type, for the protocols we might be interested in) is
meaningful. The size of the header needs to be known so it can be
skipped, allowing the IP header to be found and parsed.
It would be possible to define support for DLT_LINUX_SLL2 if it is
missing. However, if a platform is missing support in the header file
then it is almost certainly missing in the run-time library too.

The current code will almost certainly generate ENOMSG for
non-ethernet packets, even for ethernet packets when the "any"
interface is used.
pcap_datalink(3PCAP) says:
Do NOT assume that the packets for a given capture or ``savefile``
will have any given link-layer header type, such as DLT_EN10MB for
Ethernet. For example, the "any" device on Linux will have a
link-layer header type of DLT_LINUX_SLL or DLT_LINUX_SLL2 even if
all devices on the sys‐ tem at the time the "any" device is opened
have some other data link type, such as DLT_EN10MB for Ethernet.
So, pcap_datalink() must be used.
Detect pcap packet types that are supported (currently only ethernet)
in the open code. There is no use continuing if the read code can't
parse packets. The pattern of using switch statements supports future
addition of other packet types.
