ctdb-logging: Really make NOTICE the default debug level
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

librpc/nbt: Avoid reading invalid member of union
WACK packets use the ‘data’ member of the ‘nbt_rdata’ union, but they
claim to be a different type — NBT_QTYPE_NETBIOS — than would normally
be used with that union member. This means that if rr_type is equal to
NBT_QTYPE_NETBIOS, ndr_push_nbt_res_rec() has to guess which type the
structure really is by examining the data member. However, if the
structure is actually of a different type, that union member will not be
valid and accessing it will invoke undefined behaviour.
To fix this, eliminate all the guesswork and introduce a new type,
NBT_QTYPE_WACK, which can never appear on the wire, and which indicates
that although the ‘data’ union member should be used, the wire type is
actually NBT_QTYPE_NETBIOS.
This means that as far as NDR is concerned, the ‘netbios’ member of the
‘nbt_rdata’ union will consistently be used for all NBT_QTYPE_NETBIOS
structures; we shall no longer access the wrong member of the union.

smbd: call exit_server_cleanly() to avoid panicking
The parent smdb forwards SIGTERM to its process group in order to kill all
children like the scavenger. This happens from a function registered via
atexit() which means the signal forwarding is happening very briefly before the
main smbd process exits. When exiting the pipe between smbd and scavenger is
closed which triggers a file event in the scavenger.
However, due to kernel sheduling it is possible that the file descriptor event
is received before the signal, where we call exit_server() which call
smb_panic() at the end.
Change the exit to exit_server_cleanly() and just log this event at level 2
which we already do.

test: skip the open-eintr test
With 7bb8af3f74c we already had to tune the error_inject VFS object to filter
out the openat-calls coming from filename_convert_dirfsp&friends. With
the next patch openat() will be called from even more places, and I
don't really see a good way to properly deal with EINTR in all the
places where it can happen. The real case where EINTR is something we
need to handle properly I guess is with kernel oplocks active: open()
waits for another process to give up its kernel oplock, which opens
the window for EINTR to become a valid case to properly take care
of. For all other opens I would be willing to live with the fact that
we just return an error message that might be different from Windows.
To detect that kernel oplock case properly, with O_PATH we have to
look at the /proc/self/fd/<n> reopen or the O_EMPTY_PATH FreeBSD
flavor from inside the error_inject module I guess. But then, the
second time we come around the corner we have to let it pass.
