Remove horrible old repository edit controller

Summary:
Ref T2231. I didn't port these options over, so they're still supported but have no edit UI:

  - Pull Frequency (confusing/not useful, I think?)
  - Default Owners Path (probably used only by Facebook and only in the E repository)
  - Show user in public repository URL (probably mostly obsolete with hosting?)

We can add those back if users notice, but they seem like the three least useful options so I'm going to see if we can get away with removing them.

Test Plan: Clicked "Edit" from Repositories, got kicked into the nice new Diffusion edit UI instead of the old one.

Activate the new Repository creation workflow

Summary:
Ref T2231. This:

  - Activates the new multi-step workflow, and exposes it in the UI.
  - Adds "can create", "default view" and "default edit" capabilities.
  - Provides a default value for `repository.default-local-path` and forces repositories into it by default. It's still editable, but Phabricator gets it correct (for some definition of correct) by default now.

Test Plan: Created some new repositories with the new workflow.

Summary:
Basically straight from D7391. The differences are basically:

  - Policy stuff is all application-scope instead of global-scope.
  - Made a few strings a little nicer.
  - Deleted a bit of dead code.
  - Added a big "THIS DOESN'T WORK YET" warning.

Accept and route VCS HTTP requests

Summary:
Mostly ripped from D7391, with some changes:

  - Serve repositories at `/diffusion/X/`, with no special `/git/` or `/serve/` URI component.
    - This requires a little bit of magic, but I got the magic working for Git, Mercurial and SVN, and it seems reasonable.
    - I think having one URI for everything will make it easier for users to understand.
    - One downside is that git will clone into `X` by default, but I think that's not a big deal, and we can work around that in the future easily enough.
  - Accept HTTP requests for Git, SVN and Mercurial repositories.
  - Auth logic is a little different in order to be more consistent with how other things work.
  - Instead of AphrontBasicAuthResponse, added "VCSResponse". Mercurial can print strings we send it on the CLI if we're careful, so support that. I did a fair amount of digging and didn't have any luck with git or svn.
  - Commands we don't know about are assumed to require "Push" capability by default.

No actual VCS data going over the wire yet.

Test Plan:
Ran a bunch of stuff like this:

  $ hg clone http://local.aphront.com:8080/diffusion/P/
  abort: HTTP Error 403: This repository is not available over HTTP.

...and got pretty reasonable-seeming errors in all cases. All this can do is produce errors for now.

Prepare to route VCS connections through SSH

Summary:
Fixes T2229. This sets the stage for a patch similar to D7417, but for SSH. In particular, SSH 6.2 introduced an `AuthorizedKeysCommand` directive, which lets us do this in a mostly-reasonable way without needing users to patch sshd (if they have a recent enough version, at least).

The way the `AuthorizedKeysCommand` works is that it gets run and produces an `authorized_keys`-style file fragment. This isn't ideal, because we have to dump every key into the result, but should be fine for most installs. The earlier patch against `sshd` passes the public key itself, which allows the script to just look up the key. We might use this eventually, since it can scale much better, so I haven't removed it.

Generally, auth is split into two scripts now which mostly do the same thing:

  - `ssh-auth` is the AuthorizedKeysCommand auth, which takes nothing and dumps the whole keyfile.
  - `ssh-auth-key` is the slightly cleaner and more scalable (but patch-dependent) version, which takes the public key and dumps only matching options.

I also reworked the argument parsing to be a bit more sane.

Test Plan:
This is somewhat-intentionally a bit obtuse since I don't really want anyone using it yet, but basically:

  - Copy `phabricator-ssh-hook.sh` to somewhere like `/usr/libexec/openssh/`, chown it `root` and chmod it `500`.
    - This script should probably also do a username check in the future.
  - Create a copy of `sshd_config` and fix the paths/etc. Point the KeyScript at your copy of the hook.
  - Start a copy of sshd (6.2 or newer) with `-f <your config file>` and maybe `-d -d -d` to foreground and debug.
  - Run `ssh -p 2222 localhost` or similar.

Specifically, I did this setup and then ran a bunch of commands like:

  - `ssh host` (denied, no command)
  - `ssh host ls` (denied, not supported)
  - `echo '{}' | ssh host conduit conduit.ping` (works)
