Summary:
Currently, this spawns 125 concurrent processes on my machine, which overflows some limit and gives me an error:
PHP Warning: proc_open(): unable to create pipe Too many open files in /INSECURE/devtools/libphutil/src/future/exec/ExecFuture.php on line 491
Instead, limit parallelism to 16. The runtime is approximately the same for me, and dominated by other concerns (conduit calls).
Test Plan: Ran `arc branch` successfully. Ran `arc branch --trace`, observed behavior.

Summary:
The main added value is loading the branch name from revision.
Sometimes I know the revision ID but I don't know the branch name.
The missing piece is the starting point of the branch.
I was thinking about using `arc.land.onto.default` but we also need to get 'origin'.
This is also the last step of a simple workflow where underlying VCS is not abstracted away.
In future, we can implement this for other APIs.
Test Plan:
$ arc branch new_branch
$ arc branch new_branch
$ arc branch D4168

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in unit tests and LICENSE file.

Summary:
Currently, adding a new workflow requires you to override ArcanistConfiguration, which is messy. Instead, just load everything that extends ArcanistBaseWorkflow.
Remove all the rules tying workflow names to class names through arcane incantations.
This has a very small performance cost in that we need to load every Workflow class every time now, but we don't hit __init__ and such anymore and it was pretty negligible on my machine (98ms vs 104ms or something).
Test Plan: Ran "arc help", "arc which", "arc diff", etc.

Summary:
If two branches have the same HEAD, they currently race to overwrite each other in $commit_map.
We don't need to return a map indexed by commit since nothing ever reads the keys out of it. Just update $branches in place.
Test Plan: With two branches at the same HEAD, ran "arc branch". Saw both branches in output.

Summary: Currently, if you have a branch named "docs" and a local file named "docs", `git show -s docs` complains because it's ambiguous. Use `--` to unambiguously mark branches as revisions, not files.
Test Plan: Ran `arc branch` in a working copy with a "docs" branch and a "docs" file, got expected results.

Summary:
This reduces time of `arc branch` from 13s to 7s in my repo which is faster than `git branch --verbose` (10s).
The price for this speedup is that we loose the information [ahead 1, behind 21242] but we showed it only in branches with no revision so it's not a big deal.
Test Plan:
$ arc branch

Summary: See discussion in T1467. This `log` logs everything in the repo. The old command was `show -s`, I just unthinkingly converted it and it doesn't matter for non-Facebook-sized repositories.
Test Plan: Ran "arc branch".

Summary:
when a commit message contains error which fails the parsing, we 'arc branch' fails. One sample commit message we saw contains
Differential Revision: 363812, 367983, 370452
The author manually committed the code without a real revision.
Test Plan: ran on the repo with problem commit and it succeeded.

Summary:
- Move "arc branch"-specific code to the branch workflow.
- Instead of doing "git rev-parse", just do "git branch --verbose --abbrev=40".
- Use revision owners to identify ownership, not working copy identity. Particularly with the advent of "Commandeer", you might not own commits you made.
- Do a batch lookup for commits by hash (depends on D2859, but doesn't break without it).
- Use PhutilConsole for console stuff.
- Removed color from "arc list" for the moment.
- The "--by-status" flag has a slightly different output format now.
Test Plan: Ran "arc branch" in various circumstances, verified it identifies branches in immutable history repositories.
