Summary:
When importing or aliases a symbol with a `use` statement, the leading namespace separator is optional and does not modify the behavior. That is, `use \X` is equivalent to `use X`. As such, the latter syntax should be preferred because it is more concise.
According to the [[http://php.net/manual/en/language.namespaces.importing.php | PHP documentation]]:
> Note that for namespaced names (fully qualified namespace names containing namespace separator, such as `Foo\Bar` as opposed to global names that do not, such as `FooBar`), the leading backslash is unnecessary and not recommended, as import names must be fully qualified, and are not processed relative to the current namespace.

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:
Separate XHPAST linter rules in isolation from other rules and formalize the concept of a "linter rule". As the number of XHPAST linter rules grows (we currently have around 80), it becomes increasingly difficult to manage all of the test cases because `ArcanistXHPASTLinterTestCase` currently tests the entire linter (i.e. //all// linter rules) rather than testing individual rules in isolation. See D13534 for a situation in which this is painful. This is particularly bad for third party development because unit tests could break at any time depending on upstream changes.
Basically, in order to facilitate the unit testing of XHPAST linter rules in isolation, I have made the following changes:
# Added a `setRules()` method to `ArcanistXHPASTLinter`. Currently, `ArcanistXHPASTLinter` loads all `ArcanistXHPASTLinterRule` subclasses unconditionally. The `setRules()` method provides a way to override the configured linter rules.
# Formalize the concept of a "linter rule". The `ArcanistXHPASTLinterRule` class was introduced in D10541. I feel that the modularization of `ArcanistXHPASTLinter` has made the linter much more maintainable and easily testable and I intend to extend this concept to other linters, such as `ArcanistTextLinter`.
Test Plan: Ran unit tests.

(remote) origin/master -> (local) cascade-a -> (local) cascade-b -> (local) cascade-c -> (local) cascade-d
When a user lands "cascade-d" onto "origin/master", we should pull A, B and C if they aren't ahead of the remote.
If a user lands "cascade-d" onto itself, we should pull A, B, and C if they aren't ahead of the remote, then reset D to the remote.
We also find this chain if the last component of it is connected by the local branch having the same name as the remote branch (typical for "master") instead of an actual connection through tracking brnaches.

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.

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.

However, this is a bit inconsistent (other rules that fail to resolve are skipped) it is reasonable to put some default rule behind "arc:prompt" so that you can just mash enter to select it. This construction is unusual, but seems fine and sensible to me.
If you're using "arc:prompt" as the last rule, the behavior is the same as before, so this should only make the rule more useful.
