Squashed from feature/deltas-expanded.
TileCache changes:
+ add montonic sequence (wid) numbers to TileData
+ account for sizes of TileData with multiple blobs
+ simplify saving and notifying of tiles
Sends updates (via appendChanges) based on the sequence the
right mix of keyframes and/or deltas required as a single
message, and parse and apply those on the JS side.
We continue to use PNG for slide previews and dialogs,
but remove PngCache - used by document tiles only.
Annotates delta: properly as a binary package for the websocket.
Distinguishes between deltas and keyframes we get from
the Kit based on an initial un-compressed prefix
character which we then discard.
kit can be forced to render a keyframe by oldWid=0
Track invalidity on tiles themselves - to keep the keyframe around.
We need to be able to track that a tile is invalid, and so subscribe
to the updated version as/when it is ready - but we also want to
store the keyframe underneath any deltas.
force rendering of a keyframe for an empty slot in the TileCache.
force tile sequence to be zero for combinedtiles - so the client can
always request standalone tiles with explicit combinedtiles, or tile
requests.
move Blob to Common.hpp
use zero size for un-changed tiles.
remove obsolete render-id, and color deltas in debug mode.
cleanup unit tests for non-png tile results.

In 'debug' log-level we expect a detailed, but
still readable output. Having one area with
disproportionately large number of logs reduces
the overall utility of the log output.
This patch reduces a number of redundant log
entries, including errors that are already
logged. It also reduces the level of some
others from 'information' to 'debug' and
from 'debug' to 'trace'.
The goal is to make 'debug' level as useful as
possible to read the progress and be able to
understand what was going on, such that one is
able to decide which area to dig deeper into.
Then, trace level could be used to get more
insight into that area, if necessary. For
example, when investigating a test failure,
one first enables 'debug' logs and reads through.
Once a section between two debug entries is
identified as being of interest, enabling 'trace'
level logs becomes more productive as it's
now possible to easily reach the first DBG
entry and read through until the second one.
It's unfortunate that we don't have per-area
control for enabling/disabling logs, so it
is common to see more and more 'debug' log
entries added all around, making logs
less and less readable.
It is also a limitation of the levels we have
that we really only have 3 usable levels:
one, two, many. That is, 'information' for
the most important events, 'debug' for
technical details needed to investigate issues,
and 'trace' for everything else. ('warning'
and 'error' aren't really 'levels'; they have
semantics that makes them special-cases.)
So we have to avoid degrading one into the
other, or have differences without distinction.
If any of these entries are needed to be
displayed more frequently, changing them
back to 'debug' or even 'information' should
be done. Though for me they seem special
cases that don't benefit most log readings.

Normally (ideally), tiles (.bmp files) are removed as soon as the JS
has displayed them. But occasionally something goes wrong and they are
left behind. (For instance, it seems to happen if the user closes the
document immediately when it shows up.)
Do not leave them on disk until the app starts the next time.

Add `dumpState` methods to `TileQueue`, `PngCache`, `ThreadPool` classes
and call them from Document::dumpState method within kit.Kit.cpp.
Because `dumpState` method of `_websocketHandler` is protected,
currently we can't dump its internals.
Also dump the other members of the `Document` class. Note that as
`_lastMemStatsTime` is never used, we don't dump it. It seems we could
simply delete it.

chrono::system_clock can go back in time.
For time interval measurements, where we don't
care about the local time, a monotonic clock
should be used.
This avoids the server uptime jumping around
with daylight saving (or indeed by regular
synchronization with an atomic clock), among
other cases.
