Summary:
Ref T13546. See PHI1805. Currently, the "arc-ls-markers" extension doesn't run under Python 3:
- some stuff needs "b'...'" to mark it as a byte string;
- "dict.iteritems()" is gone in Python 3, and "mercurial.pycompat" isn't always available;
- in Python 3, "json" refuses to print byte strings; and
- the compiler caching behavior in Python 3 has changed.
Try to get these things working in the same way under Python 2 and Python 3.
Test Plan:
Ran this command (with `python` as Python 2, locally):
```
$ python /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers --
```
...and this command:
```
$ python3 /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers --
```
..and saw the same output in both cases (previously, `python3 ...` fataled in various ways).

Summary:
Ref T9948. Ref T13546. To identify remote branch heads -- not just modified heads -- use "branchmap" like "hg outgoing" does.
I wasn't able to find any other way to get what we want: for example, with a bundlerepo, "peer.heads()" and "peer.changelog.heads()" include local branches which are not present in the remote.
It generally seems difficult (perhaps impossible?) to distinguish between these cases by using "getremotechanges()":
- branch X exists at position Y in both the local and remote;
- branch X exists at positino Y in the local, but not the remote.
In any case, this seems to work properly and //should// do less work than "getremotechanges()" since we don't need to pull as much data over the wire.
Test Plan: Ran "hg arc-ls-markers" in various repositories, got what appeared to be a faithful representation of the remote branch and bookmark state.

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. 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:
Depends on D21067. Ref T13492. Converting unit tests to be readable exposed this error in the grammar.
Normally, "grammar_rule" rules emit a standalone Node. In this case, the bottom-level grammar rule is a collection of trivial rules and the callers configure the Node. Wrap the bottom-level rule in a configuration rule so the node is configured correctly and consistently, in exactly one place.
Test Plan: Ran unit tests.

Depends on D21066. Ref T13492. The switch of unit test data to stable/readable output exposed this bug in parsing of variadic calls: some nodes are not given types properly.
Fix the parser and update the test.

Summary:
Depends on D21063. Ref T13492. Currently, XHPAST defines a version in both PHP code and C code, and they must be kept in sync.
Switch to a single definition in PHP, then carry it through the build pipeline into C.
Test Plan: Did a clean rebuild of XHPAST, saw a version number carried in from PHP. Ran "xhpast --version".

Summary:
Fixes T9753. Changes some time ago (in D13970 + D13974) improved XHPAST build compile-time warning behavior under Bison 3.
However, macOS still ships with Bison 2.3 and these changes prevent XHPAST from building with Bison 2.3. The changes didn't introduce version detection, so Bison 2.3 builds fail somewhat mysteriously without obvious next steps.
It's relatively easy to install Bison 3 on macOS via Homebrew, but the Bison 3 changes aren't terribly substantive and XHPAST doesn't actually depend on any Bison 3 features, so just return to Bison 2.3 for now.
It would be reasonable to undo this again and retarget Bison 3 in the future, but ideally we should wait until macOS ships with Bison 3 or we have a specific reason to bump the minimum required version to 3. If/when we do, we should version-detect Bison and raise a clear error message.
Test Plan: Built xhpast under Bison 2.3 on a default macOS install using "make cleanall && make install".

This brings all the "toolsets" code into "master". We try to run commands as toolsets commands first, then fall back to older code.
Since the "toolsets" class tree is mostly parallel to the older class tree, this isn't completely broken. Currently, all commands fall back.
Test Plan: Created this diff, ran various other commands. But this is probably a long shot from finished.
