The JS code always passes in 0 for now. The server parses the parameter and
calls LibreOfficeKitDocument::setPart() before calling paintTile().
Probably also the status, key, mouse and selection messages will need a part
number. The intent is after all that the protocol is as stateless as
possible. (So maybe we should also pass the document URL in each message?)
The new function takes a map from keywords to integer values, and accepts
parameters in the form of either name=keyword, or for backward compatibility,
name='keyword'. Use it to parse the type parameter of the key, mouse,
selecttext and selectgraphic messages. This restricts the accepted keywords to
those actually valid for each message.
Needed for /usr/share/fonts so that fontconfig trusts its cache, but no harm
doing it for all directories. (Except a slight slowdown, need to see it if
has any significant impact if we would do the utime() only for directories
under /usr/share/fonts.)
Thus we need to pass the FTW_DEPTH flag to nftw() and handle FTP_DP instead of
FTP_D. We also need to make sure the directory is created also in the case of
an empty directory, for which no FTW_F callback of files inside it has been
received.
It is safest to not exit the nftw() in the FTW_SLN case.

We don't want to use WNOHANG, not sure where I got that idea from. That leads
to busy looping. The loop is in a thread of its own, so it is fine to just
wait ("hang") for some child to die.
Just use find ... -type f instead of a for loop.
One note: I wonder how text rendering by the LO code in the child process
works even if we haven't copied any actual fonts into the sys template (and
thus chroot jail)? Is FreeType (or whatever it) already present in the
process, and font files open, even before the chroot? Weird.
It was obviously very wrong to use both a unique_ptr to the
MasterProcessSession in WebSocketRequestHandler::handleRequest(), and then a
bare pointers to the peer object in the MasterProcessSession object. We got
crashes here and there related to the destructors.
Let's see if we can manage without mutexes.
There probably are more places where I should catch those and act
appropriately. At least in these places, where the websocket connection is
already closed, or being closed, anyway, the right thing to do is just to
ignore exceptions, which are generated from attempts to write to an already
closed Poco WebSocket, for instance.
