Summary: Ref T7149. We can't compute hashes of large files efficiently, but we can resume uploads by the same author, with the same name and file size, which are only partially completed. This seems like a reasonable heuristic that is unlikely to ever misfire, even if it's a little magical.
Test Plan:
- Forced chunking on.
- Started uploading a chunked file.
- Closed the browser window.
- Dropped it into a new window.
- Upload resumed //(!!!)//
- Did this again.
- Downloaded the final file, which successfully reconstructed the original file.

Summary:
Fixes T5843. File storage engines use a very old "selector" mechanism which makes them difficult to extend.
This mechanism predates widespread use of `PhutilSymbolLoader` to discover available implementations at runtime. Runtime discovery has generally proven more flexible and easier to use than explicit selection (although it sometimes needs more UI to support it in cases where order or enabled/disabled flags can not be directly determined).
Use a modern runtime discovery mechanism instead of an explicit selector. This might break any installs which subclassed the `Selector`, but I believe almost no such installs exist, and they'll receive a meaningful exception upon upgrading (any custom engines will no longer implement all of the required methods).
Looking forward, this modernizes infrastructure to prepare for new "virtual" chunked-storage engines, with the eventual goal of supporting very large file uploads and data import into the Phacility cluster.
This uses D12051 to add UI to make it easier to understand the state of storage engines.
Test Plan:
Used new UI panel to assess storage engines:

Ref T7149. This is a few steps away, but:
- Generally, I'd like to reduce the amount of "Config" configuration we have.
- One good way to do this is to move it into UIs in Application configuration. We did this with email recently.
- I think this was a great change and I'd like to keep moving in this direction.
- T7149 touches configuration related to file storage engines. Although I'm not planning to fully move configuration into applications yet, it would be easier to debug and test if I could drop a read-only panel there to show engines.
- So, modularize the config stuff so I can add a new panel without hard-coding it.

This gets the right result in 2-up, but in 1-up rows are always `<th />`, `<th />`, `<td />`, so it always detects every inline as being in the new file.

The big one is the renderer (1up vs 2up). This makes context on unified diffs come in with too many columns.
However, it impacts other parameters too. For example, at HEAD, if you change highlighting to "rainbow" and then load more context, the context uses the original highlighter instead of the rainbow highlighter.
This moves context loads into ChangesetViewManager, which maintains view parameters and can provide them correctly.
- This removes "ref"; it is no longer required, as the ChangesetViewManager tracks it.
- This removes URI management from `behavior-show-more`; it is no longer required, since the ChangesetViewManager knows how to render.

Summary:
Ref T7014. This hooks up the durable column such that when you open it up it loads your most recent Conpherence. You can then switch amongst the various widgets and stuff and everything works nicely.
Except...
- scroll bar does not work
- also doesn't work at HEAD when I add a ton of text to the UI with no changes? (wrapped $copy in array_fill(0, 1000, $copy))
- "widget selector" does not collapse when you select something else
- this part wasn't really specified so I used the aphlict dropdown stuff. didn't want to keep working on that if this was the wrong UI choice
- can not edit title
- do we still want that to be done by clicking on the title, which pops a dialogue?
- can not add participants or calendar events
- what should this UI be? maybe just a button on the top for "participants" and a button on the bottom for calendar? both on top?
- this is not pixel perfect to the mock or two I've seen around. Aside from generally being bad at that, I definitely didn't get the name + timestamps formatting correctly, because the standard DOM of that has timestamp FIRST which appears second due to a "float right". Seemed like a lot of special-casing for what might not even be that important in the UI so I punted. (And again, there's likely many unknown ways in which this isn't pixel perfect)
There's also code quality issues
- `ConpherenceWidgetConfigConstants` is hopefully temporary or at least gets more sleek as we keep progressing here
- copied some CSS from main Conpherence app
- DOM structure is pretty different
- there's some minor CSS tweaks too given the different width (not to mention the DOM structure being different)
- copied some JS from behavior-pontificate.js to sync threads relative to aphlict updates
- JS in general is like a better version of existing JS; these should collapse I'd hope?
- maybe the aphlict-behavior-dropdown change was badsauce?
...but all that said, this definitely feels really nice and I feel like adding stuff is going to be really easy compared to how normal Conpherence is.
Also includes a bonus bug fix - we now correctly update participation. The user would encounter this issue if they were in a conpherence that got some updates and then they went to a different page; they would have unread status for the messages that were ajax'd in. This patch fixes that by making sure we mark participation up to date with the proper transaction in all cases.
Test Plan: hit "\" to invoke the column and saw nice loading UI and my latest conpherence load. sent messages and verified they received A-OK by looking in DOM console. toggled various widges and verified they rendered correctly. opened up a second browser with a second user on the thread, sent a message, and it was received in a nice asynchronous fashion
