Fixes T9807. We currently run commands like this in some cases:
hg push -r master ''
From T9807, it seems that older Mercurial treated `''` in the same way it would treat no argument, while newer Mercurial does not.
Passing `''` is unusual and not intended.
Test Plan:
From T9807, @cspeckmim confirmed that running this command without the `''` works, and @jgelgens tested the patch itself.
I didn't actually run this code myself, since I don't have Mercurial 3.6.1 installed and the fix seems straightfoward.

Summary:
Fixes T9543. Fixes T9658. Ref T3855.
Major functional change is that you can have a sequence of branches like:
origin/master -> notmaster -> feature1
...where they track each other, but you named your local master something else. Currently, we resolve only one level of upstreams, so we try to land onto "notmaster" in this case, which is wrong.
Instead, keep resolving upstreams until we either hit a cycle, don't have another upstream to look at, or find someting in a remote. In this case we'll eventually find "origin/master" and select "origin" as the remote and "master" as the target.
Other minor changes:
- Make this selection process explicit.
- Make the help 3000x longer.
Also fix a bug where we could incorrectly try to tell Differential to update awith `--preview`.
Test Plan:
- Landed from a tag.
- Landed from a tracking branch.
- Landed from an nth-degree tracking branch.
- Tried to land from a local branch with a cycle in upstreams.
- Landed with --remote and --onto.
- Read `arc help land`.

Summary:
Ref T3855. Fixes T9537. Fixes T8620. Fixes T4333.
This declares bankruptcy and replaces the entire `arc land` workflow under Git. These are the notable changes:
- (T3855) You can now land from a branch to itself.
- (T3855) We now try to restore the original state very aggressively after any failure, instead of dumping you into the middle of a mess.
- (T9537) You can now land without a local branch.
- ([not actually] T9543) We'll now ignore the local branch if it just happens to be named the same thing as the remote branch but doesn't actually track it.
- (T8620) You can now land from a detached HEAD.
- (T4333) We now preserve the author and author date of whatever you land.
This may need some followup work. In particular:
- The signal handler (that tries to put you in a better place if you ^C in the middle of things) causes ^C to work awkwardly in prompts. This might not be worth it.
- Errors/instructions on push/merge issues might need work.
- I dropped support for `--delete-remote` and `--update-with-blah-blah` because I think these flags aren't worth their complexity.
- I've simplified the update/merge algorithm a bit. It may need some complexity added back in.
- I probably missed a few things because this covers like 200 unique, creative workflows.
- Users might need more guidance on the workflows that drop them in the middle of nowhere if they manage to reach them more often than I think.
Test Plan:
- Used `arc land` to land like at least 15,000 different kinds of changes.
- Landed normally.
- Landed from a branch onto itself.
- Landed from a detached head.
- Landed nothing.
- Landed with no local branch.
- Landed onto made-up branches.
- Landed with bad targets.
- ^C'd things in the middle.

-arc land now respects tracked branch when choosing 'onto'; '--onto' option remains as an override.
-arc land now respects tracked branch when choosing a remote; the remote is taken from 'onto's upstream unless the '--remote' option is present; when 'onto' branch has no upstream the '--remote' option must be provided as before.
Since 'arc feature' branches are (already) created as tracking branches, 'arc.land.onto.default' if present, is only used as the default when a non-tracking branch created by some other means is landed with out explicit '--onto'. This may be surprising but is probably the correct go-forward behavior and is inline with the description in T5690.
Test Plan:
-checked having no arc.land.onto.default still assumes 'master'
-checked 'arc.land.onto.default' still overrides 'master'
-checked upstream branch (of feature branch) overrides 'master' and 'arc.land.onto.default'
-checked '--onto' overrides all
-checked origin is default for non-tracking branches
-checked the land onto branch's upstream remote is used instead of 'origin'
-checked '--remote' overrides 'origin' and the tracked upstream

We have had trouble with arc land producing merge commits (introduced

are confused by the presence of a merge commit afterwards. Today it got even
worse since a user managed to get arc land to push the merge commit to the
server. This setting will allow us to turn it off for our uses.

Summary:
Adds error handling for several kinds of failure in arc land for
mercurial. Previously it would often leave the repo in a confusing state
if something failed.
- Aborts the land if pull brings in a diverged 'onto' branch.
- Aborts the rebase if there is a conflict. This leaves the repo exactly as
it was before, so the user is not left with a half finished rebase.
- Don't delete the original non-squashed branch until the push succeeds.
- If the push fails, strip the temporary squashed commit. This leaves the
'onto' branch back on the latest commit from the server, and leaves the users
original nonsquashed branch around.
- Always leave the user back on their original branch after an error.
Test Plan:
Ran arc land:
- with pull causing a diverged 'onto' bookmark
- with the 'onto' bookmark already diverged
- with the rebase causing conflicts
- with a push that failed due to a commit hook
- with a successful land
- with a successful collapse and land
In all failure cases the repo was left exactly as it was before arc land,
except for the push-failed case, where the only change was that the branch
was correctly on top of the destination branch due to a successful rebase.

Summary:
Mercurial 'arc land --hold' was taking 90+ seconds on our large
repository. Since most of arc land doesn't require any particular working
directory, I've changed the mercurial logic to avoid all updates except for
two: the one prior to finding the revision (only applies if the user specified
--branch), and the one at the end to leave the user in a good state.
Also got rid of a 'hg outgoing' call when phases are supported. Also changed
the hg-subversion detection to just look for .hg/svn instead of running 'hg
svn info', which was taking 4 seconds.
Now arc land takes about 50 seconds. Still much worse than git's 25 seconds.
One big hot spot is in the two 'hg rebase' calls, which account for 25 seconds
(versus 11 seconds of git).
