No need to keep such a cache here. The consumer of previews
(thumbnails) in question does it itself (Nextcloud).
This reverts commit 405b66c8db

The embedded ODF thumbnail in documents produced by OOo or LO is too
small (max 256 pixels) to be useful in general, so let's not bother.
This reverts commit 3a9e536dfa.

Needs a rebuild with STRACE_LOOLFORKIT defined, and setting the
appropriate capabilities for the strace binary.

Store the tile cache names and drop outdated tiles
times to times, so we can avoid tile rendering / sending to
stuck.

SenderQueue might drop some tiles, so we were waiting for
tileprocessed message for a tile which was not sent at all.

I used number 25 as this limit. It's an approximate value. It's enough
to handle the first 5-10 character input without waiting for tileprocessed
messages. After the first 5-10 characters the tileprocessed messages are
arriving continuously (same frequency as the typing speed), so for the later
character inputs we always have some tileprocessed messages arrived so
we can push new tiles to the network again.
This 25 upper limit also seems enough to send all tiles when a whole page is
requested (e.g. zoom os scroll).
We store the requested tiles in a list, used as a queue. I don't use std::queue
because sometimes we need to do deduplication (replace older versions of the
same tile with a newer version).
Change-Id: I22ff3e35c8ded6001c7fc160abdc1f1b12ce3bae
We always one bunch of tiles (e.g. all tiles invalidated) and we
are waiting until client send tileprocessed message back for all
tiles before sending the new tiles.
By canceltiles message we drop every previously requested tiles and
make wsd ready to send new tiles, which will be requested by the client
in theory.

When asked to "convert" a document to a PNG image, i.e. what one can
call a thumbnail, check if we have a cached PNG for the same docuemnt
already, and in that case return it.
When we have done such a convert-to operation to PNG, save the result
in the cache for later re-use.
This change adds no thumbnail cache cleanup mechanism. That will have
to be implemented separately using a cron job or whatever.
There are further improvement possibilities: For instance, if the
document is of a type that contains an embedded thumbnail (like ODF),
just extract and return that. For ODF that embedded thumbnail even
already is in PNG format.

I think the general policy should be to always log errno using both
Util::symbolicErrno() and std::strerror(), never log a naked errno.
But only in cases where we know that it is highly likely that it is
the most recent system call that has failed, so errno makes sense.

In case of integration with OC/NC, we have WOPISrc= as query param used
for load balancing. So, the earlier approach failed with integration.

Since changing the tracking state is done by toggling,
we need to wait to get the current state at load time
before we can tell whether we need to toggle it or not.
