I don't even remember how badly things broke (at least on old devices) without it, despite it making absolutely no sense at all (state-extended just flips a global that dictates whether some things get flagged as wakeup sources or not).
So, don't rock the boat too much: we don't remove it, but instead of using a sleep, we use a task deadline instead, which ensures we'll keep processing input events in the right order in the meantime. We'll already have neutered input by this point, so we'll only process power events anyway.
That means that the only iffy things are potentially *when* and *where* we have to potentially cancel that task. Resume makes sense, of course, and we log an info message to make the log flow clear; but we also do so in suspend... just in case. With a warning log because that probably indicates something fishy went on.
Also cleanup the comments while I'm there, and actually rewrite the wakeup_count stuff properly so it could actually theoretically be used if ntx kernels were actually reliable. Spoiler alert: they're not, this is still horribly broken on at least Mk < 7. Works just fine on a Forma, though, so, yay.
Fix#12325
Input events from ImageViewer can be caught between it clearing an old
ImageWidget & instantiating a new one, but before the new one has had a
chance to actually render anything.

- out-of-tree luajit-launcher build: no leftovers after `make clean`
- use the luajit library compiled by base: no point wasting time
building a second (different, possibly incompatible) version
AFAICT, this has never worked since the KPV -> KOReader refactor, as it relies on a weird little DrawContext "feature", while the actually in-use rotation framework is handled via BlitBuffer.
That kludge pollutes *a lot* of both the backend and frontend code, so I plan to annihilate that in a followup PR.
See #12303 for more context
* Use a dedicated cache hash for partial tiles from panel-zoom
* Never dump them to disk, as it confuses DocCache's crappy heuristics that rewinds the cache to skip over the hinted page to try to dump the on-screen page to disk.
* Apply the zoom factor in the exact same way as any other page rect (i.e., floor coordinates, ceil dimensions), and make sure said rect is actually a Geom so it doesn't break the cache hash, which relies on Geom's custom tostring method for rects. Said scaling method *also* belongs to the Geom class anyway.
* Handle such pre-scaled rects properly in renderPage, so as not to apply the zoom factor to the full page, which would attempt to create a gigantic buffer.
* And now that the rect is rendered properly in an appropriately-sized buffer, use the rendered tile as-is, no need to blit it to another (potentially way too large because of the above issue) blank BB.
* The zoom factor is now computed for a scale to best-fit (honoring `imageviewer_rotate_auto_for_best_fit`), ensuring the best efficiency (ImageViewer won't have to re-scale).
* Cache: Reduce the maximum item size to 50% of the cache, instead of 75%.
* Warn about the legacy ReaderRotation module, as it turned out to be horribly broken. The whole machinery (which is spread over *a lot* of various codepaths) is left as-is, peppered with notes & fixmes hinting at the problem. Thankfully, that's not how we actually handle rotation, so it was probably hardly ever used (which possibly explains why nobody ever noticed it breaking, and that nugget possibly dates back to the inception of the kpv -> ko refactor!). (#12309)
While #12256 papered over the tracking of a *single* suspend -> (resume->suspend) series of events, things still go out of sync if you tack on *more* suspend/resume events after that.
The upside is that our *actual* tracking of suspend/resume is solid, so at least we're actually doing the right thing as far as PM is concerned.
The downside is that on Kobo, the frontlight handling code is full of delays, and the ramping down/up itself also takes some time, so things can quickly overrun into the wrong event.
This means a couple of things:
* We need to cancel any scheduled frontlight toggles and ramps on Kobo, to ensure that only the one from the *last* event received goes through, in an attempt to limit the amount of potential crossover.
* Tracking fl_was_on *cannot* reliably be done from the suspend/resume handlers (especially on Kobo), as the ramps themselves may cross over the event barriers (and we potentially cancel the task anyway), so this was moved to the very few interactive callers that will actually change the frontlight state.
* On Kobo, crossover is still *somewhat* possible because the ramps take time. It's mostly harmless for the ramp down, we just need to tweak the ramp down to start from the actual intensity to avoid a weird jump on the initial step if there's an inconsistency. For the ramp up, we potentially need to manually kill the light first, because off -> on assumes it *really* starts from off ;).
Followup to #12256Fix#12246 (again)
When zooming to a small panel on a device with a large display, the
resulting zoom factor often causes `renderPage()` to only render the
panel itself instead of the whole page. `getPagePart()` needs to
account for that when extracting the panel from the rendered tile.

Getting text from xpointers to get the current selected
word context would have crengine unhighlight that word.
Allow to get it selected again when done getting context.
The item's idx field is based on the current view settings, so only trust it when there's no filtering or searches involved, which ensures the order matches the actual history array layout.
Hopefully in the least intrusive way possible, because frontlight handling code is hell.
`self.fl_was_on` could go out of sync with the expected state when resume->suspend events happened in very quick succession, leading to it being set to false, preventing the frontlight from being turned back on on the next resume.
