Depends on D18970. Ref T13049. Currently, the policy for viewing remote addresses is:
- In activity logs: administrators.
- In push and pull logs: users who can edit the corresponding repository.
This sort of makes sense, but is also sort of weird. Particularly, I think it's kind of hard to understand and predict, and hard to guess that this is the behavior we implement. The actual implementation is complex, too.
Instead, just use the rule "administrators can see remote addresses" consistently across all applications. This should generally be more strict than the old rule, because administrators could usually have seen everyone's address in the activity logs anyway. It's also simpler and more expected, and I don't really know of any legit use cases for the "repository editor" rule.

Allow SearchEngine implementations to define exportable fields so that users can "Use Results > Export Data" on any query. In particular, they can use this workflow to download a file with pull logs.
In the future, this can replace the existing "Export to Excel" feature in Maniphest.
For now, we hard-code JSON as the only supported datatype and don't actually make any effort to format the data properly, but this leaves room to add more exporters (CSV, Excel) and data type awareness (integer casting, date formatting, etc) in the future.
For sufficiently large result sets, this will probably time out. At some point, I'll make this use the job queue (like bulk editing) when the export is "large" (affects more than 1K rows?).

See PHI305. Ref T13046.
The SSH workflows currently extend `PhabricatorManagementWorkflow` to benefit from sharing all the standard argument parsing code. Sharing the parsing code is good, but it also means they inherit a `getViewer()` method which returns the ommnipotent viewer.
This is appropriate for everything else which extends `ManagementWorkflow` (like `bin/storage`, `bin/auth`, etc.) but not appropriate for SSH workflows, which have a real user.
This caused a bug with the pull logs where `pullerPHID` was not recorded properly. We used `$this->getViewer()->getPHID()` but the correct code was `$this->getUser()->getPHID()`.
To harden this against future mistakes:
- Don't extend `ManagementWorkflow`. Extend `PhutilArgumentWorkflow` instead. We **only** want the argument parsing code.
- Rename `get/setUser()` to `get/setSSHUser()` to make them explicit.
Then, fix the pull log bug by calling `getSSHUser()` instead of `getViewer()`.
Test Plan:
- Pulled and pushed to a repository over SSH.
- Grepped all the SSH stuff for the altered symbols.
- Saw pulls record a valid `pullerPHID` in the pull log.

- 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").

For normal chatter this is harmless/valid, but it causes problems when a channel has transitioned into bundle2 mode (probably it indicates "end of stream")?
In any case, it's never helpful, so if we're about to read a data block and don't have any data, just bail out until we see some more data.

A generic error response type is also supported. It consists of a an error

Summary:
Ref T13036. This code attempts to filter the "capabilities" message to remove "bundle2", but I think this has never worked.
Specifically, the //write// pathway is hooked, and "write" here means "client is writing a message to the server". However, the "capabilities" frame is part of the response, not part of the request. Thus, this code never fires, at least on recent versions of Mercurial.
Since I plan to support bundle2 and don't want to decode response frames, just get rid of this, assuming we'll achieve those goals.
I think this was just overlooked in D14241, which probably focused on the HTTP version. This code does (at least, potentially) do something for HTTP.
I'm leaving the actual "strip stuff" code in place for now since I think it's still used on the HTTP pathway.

- Added debug logging, saw this code never hit even though `hg push --debug` shows the client believing bundle2 is supported.
- Logged both halves of the wire protocol and saw this come from the server, not the client.

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>.
