Summary:
Fixes T13135. See PHI633. For at least some video files with legitimate MIME type "video/quicktime", Chrome can play them but refuses to if the `<source />` tag has a `type="video/quicktime"` attribute.
To trick Chrome into giving these videos the old college try, omit the "type" attribute. Chrome then tries to play the video, seems to realize it can, and we're back on track.
Since the "type" attribute is theoretically only useful to help browsers select among multiple different alternatives and we're only presenting one alternative, this seems likely safe and reasonable. Omitting "type" also validates. It's hard to be certain that this won't cause any collateral damage, but intuitively it seems like it should be safe and I wasn't able to identify any problems.
Test Plan:
- Watched a "video/quicktime" MP4 cat video in Chrome/Safari/Firefox.
- See T13135 for discussion, context, and discussion of the behavior of some smaller reproduction cases.

Fixes T13132. I removed this branch in D19156 when tightening the logic for the new CSP header, but there's a legitimate need for it: downloading files via `arc download`, or more generally being an API consumer of files.
This is not completely safe, but attacks I'm aware of (particularly, cookie fixation, where an attacker could potentially force a victim to become logged in to an account they control) are difficult and not very powerful. We already issue clear setup advice about the importance of configuring this option ("Phabricator is currently configured to serve user uploads directly from the same domain as other content. This is a security risk.") and I think there's significant value in letting API clients just GET file data without having to jump through a lot of weird hoops.
Test Plan:
- With `security.alternate-file-domain` off, tried to `arc download` a file.
- Before: downloaded an HTML dialog page.
- After: downloaded the file.

I've symlinked my local config to a version-controlled file now to avoid this specific type of creative self-sabotage in the future, but this has exposed a few cases where we could handle things more gracefully.
One issue is that if your favicon is customized but the file it points at can't actually be loaded, we fail explosively and you really can't do anything to move forward except somehow guess that you need to fix your favicon. Instead, recover more gracefully.

We can't currently implement a strict `form-action 'self'` content security policy because some file downloads rely on a `<form />` which sometimes POSTs to the CDN domain.
Broadly, stop generating these forms. We just redirect instead, and show an interstitial confirm dialog if no CDN domain is configured. This makes the UX for installs with no CDN domain a little worse and the UX for everyone else better.
Then, implement the stricter Content-Security-Policy.
This also removes extra confirm dialogs for downloading Harbormaster build logs and data exports.

I don't actually know if this header is useful or anyting uses it. My understanding is that it's an Outlook/Exchange thing, but we also implement "Thread-Index" which I think is what Outlook/Exchange actually look at. This header may have done something before we implemented "Thread-Index", or maybe never done anything. Or maybe older versions of Excel/Outlook did something with it and newer versions don't, or do less. So it's possible that an even better fix here would be to simply remove this, but I wasn't able to convince myself of that after Googling for 10 minutes and I don't think it's worth hours of installing Exchange/Outlook to figure out. Instead, I'm just trying to simplify our handling of this header for now, and maybe some day we'll learn more about Exchange/Outlook and can remove it.
In a number of cases we already use the object monogram or PHID as a "Thread-Topic" without users ever complaining, so I think that if this header is useful it probably isn't shown to users, or isn't shown very often (e.g., only in a specific "conversation" sub-view?). Just use the object PHID (which should be unique and stable) as a thread-topic, everywhere, automatically.
Then allow this header through for "Must Encrypt" mail.

See <https://discourse.phabricator-community.org/t/files-created-from-repository-contents-slightly-over-one-chunk-in-size-are-truncated-to-exactly-one-chunk-in-size/988/1>. Three issues here:
- When we finish reading `git cat-file ...` or whatever, we can end up with more than one chunk worth of bytes left in the internal buffer if the read is fast. Use `while` instead of `if` to make sure we write the whole buffer.
- Limiting output with `setStdoutSizeLimit()` isn't really a reliable way to limit the size if we're also reading from the buffer. It's also pretty indirect and confusing. Instead, just let the `FileUploadSource` explicitly implement a byte limit in a straightforward way.
- We weren't setting the time limit correctly on the main path.
Overall, this could cause >4MB files to "write" as 4MB files, with the rest of the file left in the UploadSource buffer. Since these files were technically under the limit, they could return as valid. This was intermittent.
Test Plan:
- Pushed a ~4.2MB file.
- Reloaded Diffusion a bunch, sometimes saw the `while/if` buffer race and produce a 4MB file with a prompt to download it. (Other times, the buffer worked right and the page just says "this file is too big, sorry").

Fixes T13031. "Enormous" changes are basically changes which are too large to hold in memory, although the actual definition we use today is "more than 1GB of change text or `git diff` runs for more than 15 minutes".
If an install configures a Herald content rule like "when content matches /XYZ/, do something" and then a user pushes a 30 GB source file, we can't put it into memory to `preg_match()` it. Currently, the way to handle this case is to write a separate Herald rule that rejects enormous changes. However, this isn't obvious and means the default behavior is unsafe.
Make the default behavior safe by rejecting these changes with a message, similar to how we reject "dangerous" changes (which permanently delete or overwrite history) by default.
Also, change a couple of UI strings from "Enormous" to "Very Large" to reduce ambiguity. See <https://discourse.phabricator-community.org/t/herald-enormous-check/822>.

Summary:
Ref T13008. Depends on D18701. The overall goal here is to make turning `enable_post_data_reading` off not break things, so we can run rate limiting checks before we read file uploads.
The biggest blocker for this is that turning it off stops `$_FILES` from coming into existence.
This //appears// to mostly work. Specifically:
- Skip the `max_post_size` check when POST is off, since it's meaningless.
- Don't read or scrub $_POST at startup when POST is off.
- When we rebuild REQUEST and POST before processing requests, do multipart parsing if we need to and rebuild FILES.
- Skip the `is_uploaded_file()` check if we built FILES ourselves.
This probably breaks a couple of small things, like maybe `__profile__` and other DarkConsole triggers over POST, and probably some other weird stuff. The parsers may also need more work than they've received so far.
I also need to verify that this actually works (i.e., lets us run code without reading the request body) but I'll include that in the change where I update the actual rate limiting.
Test Plan:
- Disabled `enable_post_data_reading`.
- Uploaded a file with a vanilla upload form (project profile image).
- Uploaded a file with drag and drop.
- Used DarkConsole.
- Submitted comments.
- Created a task.
- Browsed around.

Summary: Noticed a couple of typos in the docs, and then things got out of hand.
Test Plan:
- Stared at the words until my eyes watered and the letters began to swim on the screen.
- Consulted a dictionary.

Summary:
Fixes T12948. See that task for substantial discussion and context. Briefly:
- This workflow is very old, and won't work for large (>2GB) files.
- This workflow has become more dangerous than it once was, and can fail in several ways that delete data and/or make recovery much more difficult (see T12948 for more discussion).
- This was originally added in D6068, which is a bit muddled, but looks like "one install ran into a weird issue so I wrote a script for them"; this would be a Consulting/Support issue and not come upstream today. I can't identify any arguments for retaining this workflow there, at least.
Test Plan:
- Grepped for `files purge`, got nothing.
- Grepped for `purge`, looked for anything that looked like instructions or documentation, got nothing.
I don't recall recommending anyone run this script in many years, and didn't even remember that it existed or what it did when T12948 was reported, so I believe it is not in widespread use.
