Summary:
See PHI162. This corrects a couple more bugs:
- If the old file didn't end in a newline, we could end up printing two lines next to each other in the output.
- If the patch targeted "Line 6, character 1" instead of "line 5, character 3" in a file "1\n2\n3\n4\n5\n", we would fail to figure out what that meant when computing an offset because the last line has 0 characters on it.

Depends on D18645. Fixes T11343. Currently, when you "arc diff", we don't detect dependencies even if your working copy is on top of another open revision you authored.
Use the new Ref/Hardpoint infrastructure from the `experimental` branch to look up the revision associated with the base commit when you run `arc diff`. If it exists and there's exactly one open revision you authored associated with it, add "Depends on ..." to the summary. This is a bit rough but the whole `experimental` branch is a bit of a wilderness for now.
Also remove `--cache` (passthru flag for `arc lint --cache`, which I removed in D18643) and `getUnderlyingWorkingCopyRevision()` (no callsites).
(This won't yet work in Mercurial, and does not make sense in SVN.)

Ref T12996. `arc lint` can render in different formats with `--output <format>`.
Previously, these were a big `switch()` statement and a bunch of hard-coded stuff.
Modularize them so that that third parties could add new renderers, and this code can be refactored toward parallelizing the `lint` step.
This has a small behavioral change: we no longer hide "autofix" messages. I'd like to generally simplify the number of amend/autofix flags here, so this edges us toward that slightly.

However, it's confusing (and I think no one uses it), and we can reasonably infer what you mean if you give us `--rev`. Simplify this logic a bit and choose the "all / only changed" behavior based on the only sensible thing we can reasonably do given the flags.

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.

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.

However, we currently split the inputs into lists of characters first, then check how long they are and make a decision to bail. For //huge// inputs (e.g., 1MB+), this is too late: just splitting them has a large CPU/RAM cost.
(These inputs are rare in normal source, but can appear in, e.g., JSON files written without newlines.)
Instead, add an extra "are the inputs really huge?" check first, and bail early if they are.
Test Plan:
- Generated a 1MB "change a file full of Q to a file full of R" diff.
- Before change: purged changeset cache; took about 7 seconds to load.
- After change: purged changeset cache; took about 1 second to load.
- Viewed some normal diffs to make sure intraline edits still displayed correctly.

Summary:
Paths are passed into linters using UNIX-style slashes (/), as returned from the version control system; however,
`Filesystem::readablePath` swaps them to Windows-style (\) on
Windows when storing the names of the files with lint messages. This causes no lint message's path to match the set of
changed files, and thus no lint warnings are ever produced.
If a lint message's file is not found using the provided filename, also try looking up the UNIX-style filename, on Windows when determining if a lint mesage is "relevant."
Fixes T11248.

Summary:
Ref T7148. When uploading files from the CLI with a particular view policy, we may not respect it if the file is unique (so the data isn't already known) and small (so it doesn't invoke the chunker).
This is rare (and may never have happened outside of testing) because:
- production dumps are always larger than the minimum chunk size;
- only cluster stuff uses `setViewPolicy()`;
- the default policy is "Administrators" anyway, which is safe.
However, I caught it in local testing, so fix it up.
Test Plan: Used `bin/host upload --file ...` to upload a small, unique file. Verified it uploaded with the correct custom view policy ("No One") rather than the default view policy ("Administrators").

Summary:
The previous parser failed when only one of the old/new filenames was
quoted, as with a rename of a Unicode filename to a non-Unicode
filename, or vice versa. It also incorrectly parsed custom prefixes,
even going to far as to encode this logic in the tests: a diff of
"src/file dst/file" which is not a rename should not be recorded as
changing "src/file", but rather "file".
Switch to using the "rename from" / "rename to" as the source of truth
for old and current filenames when complex renames are done. This
matches the logic that git itself uses to parse patches; the contents
of the `diff --git` line are merely viewed as a simplest-case
prediction, with renames handled later should it not match.
The diff parser already had logic to parse "rename from" / "rename to"
lines and extract their information. As such, this diff consists
primarily of removing logic from the `splitGitDiffPaths` method, and
allowing it to quietly fail.
This resolves two ambiguity mentioned in comments and tests: in
renaming "old file old" to "file", as well as the renaming of
"old file with spaces" to "new file with spaces" when neither are
quoted.
Test Plan:
`arc unit`. Many of the existing test cases no longer
applied to the `splitGitDiffPaths` method; they were moved into a new
test method which also supplies values for "rename from" and "rename
to" lines.
As noted in the summary, this alters one of the expected values of an
existing test. Specifically, the following diff is a file addition of
`file` with custom prefixes, and not the addition of "dst/file":
```
diff --git src/file dst/file
new file mode 100644
index 0000000..1269488
--- /dev/null

Summary:
`parseGitRawDiff` dealt with the `A`, `M`, and `D` status flags from
`git diff --raw`, for file additions, modifications, and deletions
respectively. However, it failed to cope with `C` and `R` flags, for
copies and renames. Git version 2.9 and above default to resolving
renames, even in `git diff --raw` output, making this lack of support
only salient now (though users with Git's `diff.rename` set
encountered it previously).
Those two flags differ from the other three in that they offer both the
source and destination filename, separated by a tab. As
`parseGitRawDiff` was not aware of this property, it returned a
"filename" of `"oldfile\tnewfile"`. This is surfaced in several
places, including as passed to linters as a filename to check.
Needless to say, this file is nearly guaranteed to never exist on
disk.
Detect both the `C` and `R` flag types, and generate either a file
addition, or a pair of addition/deletion entries.
Test Plan:
Renamed a file, with a linter that printed each file it was
called with.

Summary:
See rARC3ffed59bd7. Currently, when a unit test includes a syntax error, it is raised in an unclear way ("error at line 10, char 1: XHP1 Unknown lint message!").
This is because each test case only activates rules it wants to test, so we lose the ID/name for the syntax message. However, we always want to test this and the lint engine can always raise it.
To get a better error message, include it unconditionally. So a test for rule `X` really tests two rules: syntax, and `X`.
Test Plan:
Ran `arc unit` at HEAD, got a better test failure:
```
FAIL ArcanistCallTimePassByReferenceXHPASTLinterRuleTestCase::testLinter

With this change, amending without commandeering is enabled by a flag in

Summary:
Fixes T10509. Pushing changes to staging can be inefficient. What happens, roughly, is:
- Master is at commit "W" -- "W" is the most recent published commit in the main repository.
- The local working copy has one change on top of that, "X", so its history is commits "A, B, C, D, E, F, ..., U, V, W, X".
- The remote has some other previous changes that I or other users have made, maybe like "A, B, C, ..., S, T, U, Y" and "A, B, C, ..., T, U, V, Z", from previous pushes to staging areas.
- "X", "Y" and "Z" will never actually make it to master, because they'll be squash-merged/amended by `arc land`.
So the local says "I want to push 'X'", and the remote says "I know about 'Y' and 'Z', are those in the history of 'W'? You only need to send me new stuff if they are".
But they aren't, so the local says "nope, so here's the whole history for you". This is slow and sends a ton of data that the remote already has over the network.
In theory, Git could use a slightly different algorithm to tell the local about more commits, but this is hard, rarely useful, and not the kind of thing I'd be excited about changing if I was the Git upstream.
Instead, when pushing "X", also push "W", to trick Git into telling future clients about it.
Now, the remote should say "I know about 'W', 'Y' and 'Z'", and the local will say "oh, great, 'W' is in history, here's just the changes since then".
Also, fail `arc diff` if the push to staging fails, and tell users to use `--skip-staging`. This code has been in production for a while and doesn't seem to have any issues, and a failed push to staging prevents builds, lands, etc.
Test Plan:
- Ran `arc diff`, saw two changes push.
- Ran `arc diff --base arc:empty`, saw only one change push.
- Ran `arc diff` with an intentionally broken staging area, saw an error.
