The failing scenario was reproducible on my old phone:
* start editing the document from the shell
* add a word
* leave the editing using the '<' in the top left
* start editing the document again => boom!
In the normali, non-crashing case, the order of destruction is that
~ChildSession is called first (and calls ChildSession::disconnect() that
consequently calls Document::onUnload() via _docManager->onUnLoad(...).
The Document::onUnload() then deregisters callbacks and all is fine.
The in the above described crashing case, the Document is destroyed
before ChildSession and calls resetDocManager() for all sessions.
Before this patch, this meant that the _docManager was set to nullptr,
leading to situation that later, in the ~ChildSession, the call of
onUnload() was avoided, the callbacks were not unregistered, and later,
on the next document load, the app crashed because it called stale
callbacks.
I suspect the change might be useful even for the non-mobile case, but
not 100% sure, so rather do it MOBILEAPP-only.

I.e. when the Document dtor clears Document::_sessions, the ChildSession
dtor may be called. But ChildSession expected that it has a valid
Document during its lifetime, which is not a promise we can hold, see
the above trace.
Fix the problem by having a pointer (and not a reference) to a Document
in ChildSession and then:
1) Clear that Document pointer in ChildSessions at the end of the
Document dtor using a new resetDocManager()
2) Check if the Document is nullptr in ChildSession::disconnect()
instead of dereferencing it unconditionally.

Now with the "Unipoll" concept all this locking is unnecessary as the
kit process is single-threaded, and actually it is harmful as the bug
shows.
Michael explains in chat:
But in fact - we should be a single threaded kit process there now. We
are protected by the solar-mutex (which is recursive) while our
locking is not. This was the whole point of the Unipoll refactor: to
remove the extra threads, complex queues, etc. etc. I just left the
mutexes. Even a recursive mutex won't work there; since it needs to be
drop-able and transferable to another (LOK internal thread) in Yield,
so - we should remove them.

Re-think the plumbing between the different parts of the C++ Online
code. Do try to have it work more like in real Online on all but the
lowest socket level. Except that we don't have multiple processes, but
threads inside the same process. And instead of using actual system
sockets for WebSocket traffic between the threads, we use our own
FakeSocket things, with no WebSocket framing of messages.
Reduce the amount of #ifdef MOBILEAPP a bit also by compiling in the
UnitFoo things. Hardcode that so that no unit testing is ever
attempted, though. We don't try to dlopen any library.
Corresponding changes in the app Objective-C code. Plus fixes and
functionality improvements.
Now it gets so far that the JavaScript code thinks it has the document
tiles presented, and doesn't crash. But it hangs occasionally. And all
tiles show up blank.
Anyway, progress.

We already use a suffix "Interface" for SocketHandlerInterface, so
rename IDocumentManager to DocumentManagerInterface.
Naming "interface" classes with an "I" prefix is C# and COM style.
Sure, that is a convention as good as any other, but let's try to be
consistent within this rather small code-base.

The app is unimaginatively called "Mobile" for now.
Runs but crashes pretty quickly after loading the document by the LO
core. Will need some heavy changes to get a ClientSession object
created in there, too, to handle the (emulated) WebSocket messages
from the JavaScript. It would then handle some of these messages
itself, and forwards some to the ChildSession, which in this case is
in the same process. Now the messsages from the JavaScript go to a
ChildSession, which is wrong. As the assertion says, "Tile traffic
should go through the DocumentBroker-LoKit WS"
use a specific message from the client for set the visibility state of
a group instead of hijacking the update row/column header message
