Use info() instead. Also, only log the info if the file actually
existed and was removed. We don't want misleading noise logging about
removing files that were not there. Use std::remove() directly to
avoid unnecessary layers that just make it harder to know whether the
removal worked or not.
All changes are supposed to be persistent. This simplifies the tile
caching code quite a lot.
The TileCache object no longer needs to keep any state whether the
document is being edited or whether it has been modified without
saving etc.
Update the modtime.txt file after saving the document. Otherwise the
tile cache would wrongly be considered invalid next time.
As a sanity check, we put a flag file 'unsaved.txt' into the cache
directory whenever we get a callback that indicates the document has
been modified, and remove it when the document is saved. If the flag
file is present when we take an existing tile cache into use, we can't
trust it.
Even after these changes, we still don't use an existing tile cache as
much (or at all?) as we could, though. The INVALIDATE_TILES EMPTY
callback that LO does early on in a conection causes us to remove all
cached tiles...
These notifications are important to be sent once the user
becomes active again to sync their view with the latest.

This also avoids the feedback loop that results from the kit
thinking the previously inactive client is now active and
sending commands (.uno:Save).

Instead of asking for individual tiles, try to find rectangular areas in the
tile requests, and ask for the large rectangles using tilecombine, instead of
asking for individual tiles.
This test requires the renderid parameter to be present in the 'tile:'
response messages, and that is the case only when ENABLE_DEBUG, so we
can run the test only in a debug build.
In a debug build it contains also the parameter renderid. (And in the
future, might be extended in other ways, too.) Construct a new request
message that has exactly and only the parameters we want.
loleaflet can now send userinactive when the user
has switched tabs or the browser window loses
focus. Similarly, it can send useractive when
focus is regained.

Will be used in unit test to verify that several clients of the same
document asking for the same tile simultaneously indeed do cause just
one tile rendering to take place.
For some reason, text cursor gets stuck making it impossible to
type in the document. This only happens with firefox + owncloud.
Lets keep the editlock state separately in map, and do not yet
mix the permissions with editlock state.

It is still possible to access them directly via loleaflet/dist/<something>,
but such use can lead to unexpected behaviour due to various caching in the
browsers etc.
Implement this for tilecombine, and do tile writes in each client's
thread separately. Add env-var. to trigger sleep, and tune it to 1
second; easily long enough to exercise this code-path.
