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.

The problem here is that we cannot run lp_set_cmdline() (directly or
indirectly via the popt helpers) until load_case_tables() has been run.
However, load_case_tables does not have auto-initialisation, so we
must init it once, and once only.

This change improves the setup_logging() API so that callers which
wish to set up logging to stderr can simply ask for it, rather than
directly modify the dbf global variable.

This removes calls to push_*_allocate() and pull_*_allocate(), as well
as convert_string_allocate, as they are not in the common API
To allow transition to a common charcnv in future, provide Samba4-like
strupper functions in source3/lib/charcnv.c
(the actual implementation remains distinct, but the API is now shared)

This patch is the second iteration of an inside-out conversion to cleanup
functions in charcnv.c returning size_t == -1 to indicate failure.

current_timestring used to return a string talloced to talloc_tos().
When called by DEBUG from a TALLOC_FREE, this produced messages
"no talloc stackframe around, leaking memory". For example when
used from net conf.
This also adds a temporary talloc context to alloc_sub_basic().
For this purpose, the exit strategy is slightly altered: a common
exit point is used for success and failure.

Swat has not been built by default for a while, so I did not notice that
the _ macro is actually used. Re-add the lang_msg_rotate function, this
time only to swat so that this is the only binary that has to take the
16k penalty.

lp_load() could not be called multiple times to modify parameter settings based
on reading from multiple configuration settings. Each time, it initialized all
of the settings back to their defaults before reading the specified
configuration file.
This patch adds a parameter to lp_load() specifying whether the settings should
be initialized. It does, however, still force the settings to be initialized
the first time, even if the request was to not initialize them. (Not doing so
could wreak havoc due to uninitialized values.)
