Summary:
Fixes T2266. Motivation:
- The lint cache does not always invalidate correctly. Because of the nature of the cache, this is a hard problem (right after "naming things").
- We already have a fair amount of complexity in trying to invalidate it, and are still discovering new places where it doesn't work (e.g., Windows with "/" vs "\" paths).
- One invalidation failure is when linter code changes, which seems unresolvable in the general case (e.g., changes to external linters).
- It's not obvious what's happening when the lint cache causes some kind of issue.
- Particularly while developing or debugging linters, your changes often won't be reflected in the lint output. Some of this is theoretically tractable but the external linter case probably isn't.
- When someone reports a problem with the lint cache in IRC or elsewhere, there is essentially never a way for me to fix it. The lint cache can't be debugged effectively without access to a working copy where the problem reproduces.
- The cache provides limited benefit outside of Facebook's install.
To remedy these issues:
- Introduce configuration which controls cache usage.
- Default it off.
- Print a message when the cache is in use.
(I'd tentatively support removing the cache entirely, but I don't know how @vrana and Facebook feel about that.)
Test Plan: Ran `arc set-config --show`, `arc lint --cache 0`, `arc lint --cache 1`.

Summary: (In fbcode and www at least, the only places I tried) if a
branch happens to be named the same as a file path (from root) (like if
a branch is called `spec` and there is a directory in `www` called
`spec`) then `arc land` will fail with git complaining that the argument
(to `git log ...`) is ambiguous as it could refer to both a path and a
revision; so this diff adds a `--` to the end so that git knows that
both are revisions and not paths.
Test Plan: Try and land something from www (I did, see D752219) where
the branch is named `spec`.

Summary:
This adds a arcconfig setting to allow specifying whether to use the merge
or rebase strategy when doing the feature branch update.
arc.land.update.default can be set to either 'rebase' or 'merge'. The command
line flags will override this setting.
We have had trouble with arc land producing merge commits (introduced
with D4080) in git. They usually appear when arc land fails, and our users
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.
Test Plan:
Verified the following combinations:
update.default not set + arc land (saw git merge in the trace)
update.default = 'rebase' + arc land (saw git rebase)
update.default = 'merge' + arc land (saw git merge)
update.default = 'rebase' + arc land --update-with-merge (saw git merge)
update.default = 'merge' + arc land --update-with-rebase (saw git rebase)

Summary:
Changes arc diff to choose the base commit as the first ancestor
that has a diff. So if your tree looks like master->A->B->C->D, if you
have a diff on B (which will include A), when you run arc diff on D it will
only include C and D.
This makes the scenario for stacked diffs nicer. A user can commit A, commit B,
arc diff, commit C, commit D, arc diff, arc land B, arc land D.
Test Plan:
Commit A on top of master
Commit B on top of A
arc diff
Commit C on top of B
Commit D on top of C
arc diff
Verify the second diff contains the changes in C and D, but not A and B.
hg up B
arc land --preview
Verify that arc land shows A and B
hg up D
arc land --preview
Verify that arc land shows A, B, C, and D
(arc land should be unaffected by this change.

Previously arc diff for hg only allowed bookmark names, rev numbers,
and commit hashes as the input base commit. This was because it escaped all
inputs and treated them as raw identifiers.
This change makes it treat the input as a revset if the escaped version fails.
This allows users to do things like "arc diff .^" when they only want to diff
the top commit.

Created a stack of commits, master->A->B.

Summary:
The `emailuser` template is a relatively recent addition to Mercurial, and a few users have complained about it. It also doesn't actually do what I thought it did, e.g. in an address like this:
"Abraham Lincoln" <alincoln@whitehouse.gov>
^^^^^^^^^^^^^^^ ^^^^^^^^
(1) (2)
^^^^^^^^^^^^^^^^^^^^^^^
(3)
...I want (1), but `emailuser` means (2). Instead, extract (1) with `getDisplayName()` and (3) with `getAddress()` using PhutilEmailAddress.
The implementation in Mercurial is not particularly sophisticated or magical (it just looks for "@" and "<") so we aren't really missing anything by doing this ourselves, at least today.
Also fix some issues in `arc export`, which literally no one uses, but which is occasionally useful for testing (as here).
Test Plan:
- Ran `arc diff --only` in an `hg` repo, checked DB to see that name/email were correctly extracted.
- Ran `arc export --git` in an `hg` repo, didn't get a long series of fatals.

Summary:
This adds a hook to allow external parties to provide config settings at runtime.
The hook is technically for when a RepositoryAPI is created, but that moment can
be used to set new config settings using the new setRuntimeConfig() api.
For example you could have a external hook that looks for keys like 'git:foo.bar'
or 'hg:foo.bar' and writes the value of 'foo.bar' based on whether the repo is a
git or a hg repo.
Test Plan:
Created a hook that looks for hg/git prefix versions of config keys.
Set hg:arc.feature.start.default to be "master" and set arc.feature.start.default

Summary:
Previously, arc patch would create a new commit under the existing
current bookmark in mercurial. There have been two discussions about what the
right behavior should be (D3334 and D3658). One side wants no commit at all,
and one side wants a commit under a new bookmark. The current implementation is
the worst of both worlds :(
This change makes it create a new bookmark at the revision's base before commiting,
same as the --bookmark flag used to do (which is now obsolete). That way the
existing bookmark doesn't move (in mercurial >=1.8). This is the same behavior
git has, which is convienent for groups migrating between the two.
Also makes hg's getCanonicalRevision handle svn revisions just like git. This way
arc patch will try to apply the patch to the appropriate revision in the history.
Test Plan:
Ran:
arc patch - Verified it created a new bookmark and commited on top of the
revision's base commit.
arc patch --nobranch - Verified it put the new commit on top of the current
bookmark without a new bookmark.
arc patch --nocommit - Verified it left all the changes in the working copy.
Also verified arc patch still works with git.

Summary:
- Added arc.autostash option to have this behaviour off by
default (but configurable on a per-project basis).
- Automatic stashing of changes now informs the user of how

- Fixed an issue with finalizeWorkingCopy when the workflow
didn't require a clean working copy.
Test Plan:
Test `arc diff` when there are changes in the working
directory; by default it should tell you to stash or commit.
Turn on the arc.autostash option and try again; it should
automatically stash with a message on how to recover, and
it should restore the working directory automatically under
almost any circumstances (other than an unrecoverable error).

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.
Used bookmark name "foo bar-gah" to test that crazy bookmark names still work.
