Using a new internal command, when a client disconnects
an internal 'disconnect' message is dispatched so
the child process cleans up the ChildSession in question.

Which is sometimes stored in a bool, but when auto is used, it's char*,
so it helps to have that written explicitly.

By default LOK doesn't provide the part where the invalidated
tile is. The part # is found using API, but due to the fact
that callbacks are processed asynchronously, the part #
may well have changed by the time the invalidation is
processed. This could result in buggy invalidations
where no modification took place.
With the new API flag LOK_FEATURE_PART_IN_INVALIDATION_CALLBACK
the part # is included in the callback, which is parsed
and used to inform the client with the correct part #.

Instead of trying to inform the sysadmin (which we did not yet try to
do in any meaningful way), inform all connected clients (even those
editing other documents).
We use 'error: cmd=internal kind=diskfull' as the message to the
clients. The loleaflet code needs to be updated to handle that
carefully by displaying a very prominent message that tells the user
that all bets are off.
Also add a unit test for the functionality.
Document the new protocol details.
The code for this alert functionalty became a bit less elegant than I
like because of the way we include Util.cpp in the unit test 'test'
program.
Still need to add code to check for disk full in more places, not just
when saving a cached tile or font. Probably we should even actually
check for disk space on the file system(s) we use getting alarmingly
low, not just check for file writing operations that fail. Later.
The missing init of mutexes is probably theoretical, the TraceFile and
the Unit ones were real errors, I think.

Instead of 2 queues and 2 threads, merge those to one - which gives a perfect
ordering of the invalidations and rendering.

This replaces addview/remview/remallview messages in the protocol
with 'viewinfo' message which is sent whenever there is any
change in the view information.
Let the client deal with what information is redundant to it.

Seems to fix the deadlock problem, or at least makes it very much
rarer. (I am not entirely certain that a callback might not be in
progress already (in another thread) when we turn off callbacks, and
in that case the callback might still then access freed memory?)
If the connection thread is not running when loading a
document, the callback will drop events. This can happen
when the thread is too slow to spawn, but we return from
the createSession function and process client messages.
This should solve the race where we lose notifications of
other views when a new view is created.

Act as if it was always set.
The ChildSession::_multiView field will always be true, so factor it
out. Ditto for Document::_multiView.
The ClientSession::_haveEditLock will also be always true, so factor
it out. This means the ClientSession::isEditLocked() will always
return true, so factor it out, too.
ClientSession::markEditLock() always will always set _haveEditLock to
true (which it will be from the constructor already anyway) so it can
be removed.
ClientSession::setEditLock() does not need a parameter as the
parameter was actually only used for misleading logging. The msg
variable constructed in the function used isEditLocked(), not the
parameter.
We still generate and handle editlock messages. Not sure whether that
makes any sense, though.
- lok::Document::setCallbackLatch: used on doument loading for
set/unset the latch
- now cell cursors of other views are correctly notified to the new
view
- lok::Document::setCallbackLatch: used by a child session for
set/unset the latch
- lok::Document::registerCallback has a new boolean parameter used for
setting the latch state just before the callback is actually
registered for a (new) view
- now cell cursors of other views are correctly notified to the new
view
