Also, don't let these tile previews change part of the document
permanently. This is a temporary solution till we have some
better API from LOKit to deal with such a situation.

Obviously this is dangerous, since the id is not part of the
subscription key (the filename) so different clients could
have different ids on the same part, but in practice I
expect this not to happen. Though that clearly depends on
how clients use the id.

Piggyback editlock information to tile messages so that kit can
use that information to allow changing parts only for messages
with editlock.
... and decline tile render request for tile messages without editlock
information

For the moment, it will allow running 'make check' that does not conflict with
an already running loolwsd (eg. from 'make run'). Later we can consider
running more tests in parallel.
WSD's DocumentBroker and Kit's Document now handle
the communication of tiles as well as all aspects
of rendering, caching, unifying requests and
distributing results etc.

While there are two separate callbacks registered
(one with lokit and the other with lokitDocument,)
there is no reason why they should be handled
separately (and indeed differently).
The lokit callback only sends notifications on
status indicator (during loading and saving)
and document password type (if protected).
Due to the different callback handlers
the status indicator was only sent to the
first client, not all (as one expects).
Furthermore, because the lokit callback
was processed on the Core thread, it
was bound to cause performance and
thread-safety issues. Specifically it
deadlocked when another callback was
in flight when a save issued status
indicator callback.
By unifying the callbacks and putting
all callback messages on the message
queue we avoid all of the above and
simplify the code.

When loading a document first we set the rendering
options. Beyond that, the document is shared and
we shouldn't change the rendering options.

The closing handshake.
Either peer can send a control frame with data containing
a specified control sequence to begin the closing handshake.
Upon receiving such a frame, the other peer sends a
Close frame in response, if it hasn't already sent one.
When inside the chroot, what we would need to do is remove everything
below / . But doing that is a bit too risky, in case some developer
screws up some detail and that code happens to run outside the chroot
after all, and the developer's machine gets trashed. So just remove
paths we can reasonably assume won't exist as global pathnames on a
developer machine: loSubPath and JAILED_DOCUMENT_ROOT.
Currently the actual complete cleanup of loolkit jails happens in
loolwsd when it is exiting. That is a bug and will have to be
fixed. It should be done in loolforkit as soon as possible after the
loolkit process has exited.
This ensures that bundled fonts in instdir/share end up resolved to
the same path that they were in when the forkit font config was setup.
It may also help locate other pre-inited resources.
Also copy in ~/.fonts in debug mode - can't hurt.
SocketProcessor doesn't need to take response

Connection thread should not attempt to disconnect the session,
which in turn will try to unload the document, which will
wait on the connection to destroy. The latter will never
happen since the connection destructor must, correctly,
wait for its thread to finish, which is waiting on itself now.
Since the session disconnect is already called from the session
destructor, there is no need to explicitly invoke it here.

This seems to get rid of the "terminate called after throwing an
instance of 'Poco::SystemException'" problem for me at least.
Sigh. Why can't the compiler warn about such things? I build with
clang++ -Wall -Wextra. The Connection class is fully defined inside
the LOOLKit.cpp so it should be able to, right?
Presumably it is only developers that are interested in signals, and
terms like SEGV or ABRT are more precise than their textual
descriptions like "Segmentation violation" or "Aborted".
Sleep a second before exiting in case we get a fatal signal just when
about to finish, which sadly seems to happen often. (In fact, if
handleFatalSignal() is running at the same time, it will kill the
process so we never get to the _Exit() call.)
The logging functions already display the thread name on all output
lines. No need to mention it another time in the thread start and
finish logging messages.
A call to Log::error() should be enough to indicate that it is an
error. We don't need to prefix the message with the string "Error: "
in some cases but not others. (If we do want such a prefix for all
errors, surely then we should add it in the actual Log::error()
function.)
Also, change some more Log::error() calls to Log::syserror() where
appropriate.
Admin no longer needs a pipe as it's notified
from WSD. It is now a singleton with improved
locking.
The tracking of documents and views still needs
improvement and corrections.
