This avoids this structure being partially uninitialised.

Since the fix for bso#7836, the parent smbd is responsible for
maintaining an up-to-date printcap cache. It does this by forking a
child process to asynchronously fetch printcap data from CUPS.
When the child process exits after fetching all printcap data, the
parent smbd is sent SIGCHLD. This triggers smbd_sig_chld_handler() which
looks for the exited process PID on a "children" list.
Child smbd process PIDs are added to the "children" list to ensure
cleanup on unclean shutdown and log level change notification messages.
Printcap update process PIDs are not added to the list as they do not
maintain any state that requires cleanup, nor do they wait on tevent for
messages.

Start of the move towards handle-based code for directory access.
Currently makes fstat/fchown code work for directories rather than
falling back to pathnames.

make it comprehensible.
delay_for_oplocks() did 4 things.
1). Validation of existing oplock types.
2). Check for compatibility with batch oplocks (pass 1).
3). Check for compatibility with exclusive oplocks (pass 2).
4). Set the correct oplock type from the requested value.
Refactor into 4 separate functions:
1). find_oplock_types() - does validation of oplock types and
returns pointers to specific values.
2). delay_for_batch_oplocks() - the pass 1 phase above.
3). delay_for_exclusive_oplocks() - the pass 2 phase above
4). grant_fsp_oplock_type() - Set the correct oplock type from the requested value.
Now separated out this code should be much easier to understand
and modify. This also fixes an erroneous SMB_ASSERT which was
hidden by the previous complexity of the single delay_for_oplocks()
code.

Otherwise a Win7 client issues this request twice (2xroundtrips)
if we return NOT_SUPPORTED. We do the same for SMB1 in call_trans2qpipeinfo()

copy_file():
- Firstly, if the source file is zero bytes, NT_STATUS_DISK_FULL is
returned.
- Secondly, the conditional lseek is confusing. It fires when
OPENX_FILE_EXISTS_OPEN is set and I can't see why the lseek is
necessary in this case.
- Finally, the lseek error path also results in NT_STATUS_DISK_FULL.
Proposed fix for first and third point below.

Do this by keeping a linked list of delete on close tokens, one for
each filename that identifies a path to the dev/inode. Use the
jenkins hash of the pathname to identify the correct token.

Do the notification after we released the share mode lock. Inside notify_fname
we take out another tdb lock. With ctdb also accessing our databases, this can
lead to deadlocks. Putting this notify after the TALLOC_FREE(lck) above we
avoid locking two records simultaneously. Notifies are async and informational
only, so calling the notify_fname without holding the share mode lock should
not do any harm.

Since commit 7022554, smbds share a printcap cache (printer_list.tdb),
therefore ordering of events between smbd processes is important when
updating printcap cache information. Consider the following two process
example:
1) smbd1 receives HUP or printcap cache time expiry
2) smbd1 checks whether pcap needs refresh, it does
3) smbd1 marks pcap as refreshed
4) smbd1 forks child1 to obtain cups printer info
5) smbd2 receives HUP or printcap cache time expiry
6) smbd2 checks whether pcap needs refresh, it does not (due to step 3)
7) smbd2 reloads printer shares prior to child1 completion (stale pcap)
8) child1 completion, pcap cache (printer_list.tdb) is updated by smbd1
9) smbd1 reloads printer shares based on new pcap information
In this case both smbd1 and smbd2 are reliant on the pcap update
performed on child1 completion.
The prior commit "reload shares after pcap cache fill" ensures that
smbd1 only reloads printer shares following pcap update, however smbd2
continues to present shares based on stale pcap data.
This commit addresses the above problem by driving pcap cache and
printer share updates from the parent smbd process.
1) smbd0 (parent) receives a HUP or printcap cache time expiry
2) smbd0 forks child0 to obtain cups printer info
3) child0 completion, pcap cache (printer_list.tdb) is updated by smbd0
4) smbd0 reloads printer shares
5) smbd0 notifies child smbds of pcap update via message_send_all()
6) child smbds read fresh pcap data and reload printer shares
This architecture has the additional advantage that only a single
process (the parent smbd) requests printer information from the printcap
backend.
Use time_mono in housekeeping functions As suggested by Björn Jacke.

Since commit eada8f8a, updates to the cups pcap cache are performed
asynchronously - cups_cache_reload() forks a child process to request
cups printer information and notify the parent smbd on completion.
Currently printer shares are reloaded immediately following the call to
cups_cache_reload(), this occurs prior to smbd receiving new cups pcap
information from the child process. Such behaviour can result in stale
print shares as outlined in bug 7836.
This fix ensures print shares are only reloaded after new pcap data has
been received.
