Summary:
Ref T12996. Fixes T9749. This is a very old Facebook-specific thing which relies on other server-side Facebook-specific things and doesn't work properly anyway.
I don't actually remember what the use case for this flag was. It was either "the codebase has a million warnings, so showing warnings on files/lines you touched isn't good enough", or "weird warnings that raise lint on other lines", or some variation of those.
Regardless, I believe this feature benefits at most one install (Facebook circa 2011), and likely zero. It occasionally confuses normal users.
T9749 suggests a possible replacement workflow which is likely more practical, but I'd like to see a real problem description before considering this again.

See PHI13. This was introduced a very, very long time ago in D311 and D312, and I think T168 was the original report.
It prevents `arc` from being used in some semi-reasonable (maybe?) automation workflows where you're hooking some version of "Land Revision" up to `arc land`. This isn't necessarily the right approach, but I think the concession here to make this work is small.
Running `arc` against another copy of `arc` makes `arc unit` not work, but we provide a good error message. Most other `arc` operations still work correctly.
All of these situations are bizarre edge cases but I think we can safely warn and continue here. Even if we revert this behavior later, almost no one should be affected, since this essentially only impacts users developing `arc` itself.
Test Plan: Ran one copy of `arc` against another, saw a warning instead of an error. `arc unit` failed, but with a good error.

Summary:
Because the character offset group is optional, the logic for dealing
with the previous index-based match object was more complex than it
needs to be. Switching to named groups makes this clearer.
As an example of how this was causing a problem, when the character
group *was* present (at index 3), it was being appending to the linter's
name in the call to ->setName(), resulting in confusing linter output.
We may have also been setting the character offset to the error code's
string, too, which is further nonsense.
Because we reliably capture the flake8 error code, I don't think there's
a need to append it to the linter's name at all now, so I removed that
part (so it's always just `flake8`), but it's not a problem to restore.
Lastly, I hoisted `$regex` out of the loop because it's a constant and
de-indenting it gave me enough room to continuing writing it all on one
line.

Ref T11355. Ref T10895. Ref T11518. This is heading to `experiemntal`. This may or may not be a good idea, but basically it's a more generic version of `Query` classes in Phabricator.
This starts creating generic objects ("CommitRef", "BranchRef") which have attachable properties, like many Phabricator objects do. Here, they're formalized (and theoretically extensible), as "hardpoints".
So: a hardpoint is something on an object which you can attach stuff to, but which we don't start with the data for.
All of the logic for actually figuruing out how to attach stuff to hardpoints is also modular. `Loader` classes have code for loading stuff onto objects. For example, `ArcanistMercurialBranchCommitHardpointLoader` knows how to run `hg log` to build the commit for a branch.
One issue is that `arc feature` in Mercurial is 100% bookmarks, so maybe I should actually be making `ArcanistRefRef` here. But we can probbbably deal with that later.
This moves us somewhat closer to T11355 and T11518, although the immediate thing I want to do with it is define an `ArcanistObjectNameRef` and use hardpoints to load URIs for it for T10895.
Overall, I expect this will see some revision in future changes, and perhaps most of it will go away.

Summary:
Ref T10895.
NOTE: I'm going to land this and other changes to a new `experimental` branch until `arc` is more substantially rebuilt, since everything I touch feels like it requires me to rebuild 30 other things first.
Currently, many `arc` workflows are unnecessarily slow because they call `conduit.connect` on startup. There's no need to do this with the modern way the API works, and we've generally moved away from explicit version testing to more granular capability testing on specific workflows.
Additionally, some workflows like `arc patch` are huge messes (see T11434) because they're trying to run in anonymous mode but it doesn't really work with all the upfront stuff Conduit does now. It's not possible, in the general case, for a workflow to know upfront if it needs Conduit or not.
And:
- `ArcanistWorkflow` has piles of Conduit logic, but should not.
- Pooling Conduit requests isn't very easy.
- There's a lot of general cruft around the workflow.
- We should drop certificate support.
This pulls out Conduit into a separate on-demand class with modern support, future pooling, less cruft, inline handling of login issues, and generally less garbage.
Also adds an `--anonymous` flag, mostly to make testing easier.
Test Plan: Ran `arc browse`, used `--anonymous` and `--trace`, fiddled with credentials, got approximatley the same behavior that mainline `arc` has.

Instead, add an extra "are the inputs really huge?" check first, and bail early if they are.
