Summary:
Ref T13546. Show ongoing and failed builds more clearly in "arc land" output.
Also rename "DisplayRef" (which is not a "Ref") to "RefView" with the goal of improving clarity, and let callers "build...()" it so they can add more status, etc., information.
Get rid of "[DisplayRef|RefView]Interface". In theory, future refs (say, in Phabricator) might not do anything here, but every Ref just ends up implementing it. This could perhaps be subclassed more narrowly in the future if necessary.
Test Plan: Ran "arc land", grepped for various symbols.

Summary:
Ref T13546. Ref T9948.
- Make "--hold" show the same set of commands to manually push that the normal workflow would use.
- Make save/restore state work.
- Make bookmark creation prompt for confirmation.
- Improve / provide some additional warnings and help text.
Test Plan: Ran various increasingly complex "arc land" workflows, e.g. "arc land --hold --onto fauxmark1 --onto fauxmark2 --into default . --revision 118 --trace"

Summary: Ref T9948. Ref T13546. Clean up some minor behaviors to allow "arc land" to function in the simplest cases again. Also, do a capability test for "prune" rather than just falling back.
Test Plan: Ran "arc land <mark>" in Mercurial, got changes pushed.

Summary:
Ref T9948. Ref T13546. This change moves toward a functional "arc land" in Mercurial.
Because of how "bundlerepo.getremotechanges()" works, "hg arc-ls-markers" does not actually list markers in the remote that aren't different from local markers so it's hard to get anywhere with this.
Test Plan: Got somewhat-encouraging output from "arc land" and "hg arc-ls-markers", but too many things are still broken for this to really work yet.

Summary: Ref T13546. In the new "arc land": actually reach build warnings; and show buildable URIs.
Test Plan: Ran "arc land ..." with intentionally broken builds, got more useful build warnings.

Summary: Ref T13546. The modern constant from the modern API method for this state is "published", and this more narrowly covers the desired behavior (notably, excluding "Abandoned" revisions).
Test Plan: Ran "arc land ... --revision X" where "X" is a published revision, got an appropriate prompt.

Summary:
Ref T9948. Ref T13546. We must passthru "hg ls-remote" because it might prompt the user for credentials.
Since "ls-remote" is implemented as an exension and we can't rely on using stdout beacuse of passthru, the actual command we execute is:
```
$ hg --config extensions.arc-hg=<huge long path to extension> arc-ls-remote --output <huge long path to temporary file> -- remote
```
This is meaningless and distracting; show the intent of the command we're executing instead. Users can see the raw command in "--trace" if they're actually debugging behavior.
Test Plan: Ran "arc land" in a Mercurial repository, got a tidier command output.

Summary: Ref T13546. Ref T9948. It seems challenging to examine a remote in vanilla Mercurial. Provide an "hg arc-ls-remote" command which functions like "git ls-remote" so we can figure out if "--into X" is a bookmark, branch, both, neither, or a branch with multiple heads without mutating the working copy as a side effect.
Test Plan: Ran various "arc land --into ..." commands in a Mercurial working copy, saw apparently-sensible resolution of remote marker names.

Summary: Ref T13546. Parse "hg paths" and validate that the remotes "arc land" plans to interact with actually exist.
Test Plan: Ran "arc land" with good and bad "--into-remote" and "--onto-remote" arguments, got sensible validation behavior.

Summary:
Ref T13546. If the "onto" branch doesn't exist yet and has a "/" in it, we need to preface it with "refs/heads" explicitly.
Fix a "false/null" issue with argument validation.
Possibly, "arc land" should prompt you before creating branches in the remote.
Test Plan: Ran "arc land --onto does-not-exist/1.1" and created a branch.

Summary:
Ref T13546. If you have "feature1", "feature2", etc., "arc land feature4" will now land the entire sequence.
Provide "arc land --pick feature4" to work more like the old "arc land" did. This cherry-picks the commits associated with "feature4", then cascades onto the ancestor of the range.
Test Plan: Ran "arc land --pick land14" to pick a change out of a stack.

Summary:
Ref T13546. When we encounter a merge conflict, suggest "--incremental" if it's likely to help.
When merging multiple changes, rebase ranges before merging them. This reduces conflicts when landing sequences of changes.
Test Plan: Ran "arc land" to land multiple changes. Hit better merge conflict messaging, then survived merge conflicts entirely.

Summary: Ref T13546. Fixes T2928. Adds a new "arc work" workflow which functions like the older "arc feature" workflow, but with modern infrastructure.

Summary: Ref T13546. When users hit a situation where we would select "squash" but would previously select "merge", prevent them from continuing under ambiguous conditions.

Summary:
Fixes T13380. Ref T13546. Use slightly nicer command formatting for passthru commands, to make it more obvious what's going on and which pieces of output are from "arc" vs various subcommands.
Also, execute repository API passthru commands from the working copy root. All other commands already did this, the older API just didn't support it.
Test Plan: Ran "arc land" in Git and Mercurial repositories, saw nicer output formatting.

Summary: Ref T13546. This is mostly minor cleanup that improves behavior under "--revision".

Summary:
Fixes T12876. Ref T13546. When you make the first change in a new Git repository, "arc land" currently can not merge it because there's nothing to merge into.
Support merging into the empty state formally, reachable by using "--into-empty" (which should be uncommon) or "arc land" in an empty repository.
Test Plan:
- Used "arc land --into-empty --hold ..." to generate merges against the empty state under "squash" and "merge" strategies in Git.
- Got sensible result commits with appropriate parents and content.

Summary:
Ref T13546. When we find commits in history which are associated with already-closed revisions, and they weren't named explicitly on the command line, and we're using a squash strategy, discard them.
This generally happens when "feature2" is on top of "feature1", but "feature1" gets amended or branched elsewhere and lands independently.
Test Plan: Ran "arc land feature3" where prior revisions had already landed, got discards on the duplicated changes.

Summary: Ref T13546. When "arc land" performs cascading rebases, do them in "feature1", "feature2", etc., order so they're easier to follow. The outcome is not dependent on execution order.
Test Plan: Landed a change which cascaded many other branches, saw more comprehensible update order.
