auto-save (or explicit save by tapping the button), the edited
document does show up with its auto-saved contents if you open it from
iCloud Drive or Nextcloud while it is still open in the iOS app.
What I was missing was that the document hadn't actually been saved by
the core (to the temporary copy) until we get the
LOK_CALLBACK_UNO_COMMAND_RESULT for the .uno:Save. We must call the
-[UIDocumentsaveToURL:forSaveOperation:completionHandler:] only upon
receiving that callback.

In linkOrCopy, the nftw() function is used without the FTW_PHYS flag to
populate child roots from systemplate. From man nftw:
FTW_PHYS
If set, do not follow symbolic links. (This is what you want.)
If not set, symbolic links are followed, but no file is reported twice.
Because the order in which directory entries are visited is not defined,
having multiple symlinks to a file results in only one of the paths
being created in the chroot.
This is not really a problem because loolwsd-systemplate-setup creates
systemplate without symlinks. Fixing it might prevent unpleasant
surprises in the future though, and might possibly allow to make
systemplate and chroots smaller (also the manpage says that you want
it:)).
The commit adds FTW_PHYS flag to the call as well as symlink handling.

The 'exit' command from DocBroker to Kit is processed
immediately. It set the termination flag and destroyed
the Document instance in Kit. Unfortunately, this is
highly problematic. There are a number of races here.
Normal disconnection procedure from DocBroker is to
first send 'disconnect'. This tells Kit to unload
and close the view in question, and when 0 views
are left, it simply exits the process.
However, since 'disconnect' is processed in the
message queue, the 'exit' (and indeed the socket
disconnection that follows 'exit') may be handled
before the message queue is drained, and so the
'disconnect' wouldn't have been processed yet.
The end result of these two races is that Kit
tries to exit the Core main loop, which fails
a number of assertion (f.e. that no LOK Windows
remain, which is presumably a leak check, which
we care not about as we don't attempt to cleanup
the sidebar).
The fix here is to process 'exit' immediately,
because DocBroker is gone, there is absolutely
nothing for Kit to do anymore.

This is meant to reduce lots of small allocations and instead have
pointers into the single string for the various tokens instead.
This has a few requirements, though:
1) It's no longer OK to modify the tokens, changing their length would
invalidate the start/length of other tokens. Rework
DocumentBroker::load() to avoid such mutation.
2) The iterators no longer expose zero-terminated strings, so
Poco::cat() doesn't work anymore: add an own cat() instead and use that
in e.g. ChildSession. The own cat() has the benefit that it won't read
past the end of the array if the begin index is out of bounds to add
more safety.
(This nicely works towards killing Poco usage in general.)
3) If zero-terminated strings for all individual tokens is needed, a
copy has to be made, as done in spawnProcess().
(For all of these requirements, the build fails if there are problems.)

The bulk of this commit just changes std::vector<std::string> to
StringVector when we deal with tokens from a websocket message.
The less boring part of it is the new StringVector class, which is a
wrapper around std::vector<std::string>, and provides the same API,
except that operator[] returns a string, not a string&, and this allows
returning an empty string in case that prevents reading past the end of
the underlying array.
This means in case client code forgets to check size() before invoking
operator[], we don't crash. (See the ~3 previous commits which fixed
such crashes.)
Later the ctor could be changed to take a single underlying string to
avoid lots of tiny allocations, that's not yet done in this commit.

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.

This adds table markers for resizing rows and columns if the user
has the table selected or the cursor is in the table. The code
reacts to the callback "tableselected:", where the markers are
created for each column and row, if the payload (json) of course
has any data. When the marker is dragged, a uno command to resize
the table column or row border is send to the core.

handles onerror properly, which invokes the error

it was ignored.
