Implement writes over HTTP for Git.

Summary: Depends on D7642.  This updates the authentication logic so that HTTP writes can be made to Git repositories hosted by Phabricator.

Test Plan: Set the policy to allow me to push and I was able to.  Changed the policy to disallow push and I was no longer able to push.

Mark IMPORTED_CHANGE more consistently

Summary:
See <https://github.com/facebook/phabricator/issues/425>. There are some ways that the change parsers may not reach `finishParse()`, but we now need them to in order to mark the commit imported, advance the progress bar, and eventually kick the repository out of IMPORTING status.

Take all the copy/pasted code in the parsers and move it into the parent. Specifically, this is:

  - Printing a status message about starting a parse;
  - checking for bad commits;
  - queueing the next parse stage; and
  - marking the import step complete.

Test Plan: Used `reparse.php --change` to reparse Git, SVN and Mercurial repos.

Improve repository hinting and feedback

Summary:
  - Warn about "Read/Write" instead of disabling it, to prevent edits which mutate it after changing a hosted repository to an unhosted one.
  - Warn about authenticated connections with HTTPS auth disabled, and link to the relevant setting.
  - When "Autoclose" is disabled, show that "Autoclose Branches" won't have an effect.
  - For hosted repositories, show the HTTP and SSH clone URIs.
    - Make them easy to copy/paste.
    - Link to credential management.
    - Show if they're read-only.
    - This could be a bit nicer-looking than it is.

Test Plan: Looked at repositories in a bunch of states and made various edits to them.

Survive pull/discover for hosted repositories in all VCSes

Summary:
Hosted repositories only sometimes survive the pull/discover phases right now, due to issues like:

  - Pull tries to `git clone`, but should `git init`.
  - Mercurial doesn't handle empty repositories with on branches.
  - SVN tries to connect to an invalid remote.
  - None of them set the INIT repo flag correctly, so status doesn't get updated properly in the UI.

Fix all this stuff.

Test Plan:
  - For each of Git, SVN and Mercurial:
    - Created a new repository from the web UI in a deactivated state.
    - Made it hosted.
    - Manually ran pull/discover.
    - Verified we end up with initialized, empty repositories in consistent states.

When creating a repository in Diffusion, prompt for "Create" or "Import" first

Summary:
Ref T2230. This will need some more refinement, but basically it adds a "Create" vs "Import" step before we go through the paged workflow.

  - If you choose "Create", we skip the remote URI / auth stuff, and then set the "hosted" flag.
  - If you choose "Import", we do what we do now.

Test Plan: Created and imported repos.

Minor, restore a missing "break;" that I derped somehow.
Fix issue where Git authentication would always 403 on non-public install.

Summary: This fixes an issue where Git authentication would always fail on an install with `policy.allow-public` set to false.  This is because when public access is allowed, anonymous users can query the user list.  However, when public access is not allowed, you have to be authenticated before you can read any of the user objects.

Test Plan:
Prior to this fix, I get:

```
james@james-laptop:~/git/8> git clone http://phabricator.local/diffusion/TEST/
Cloning into 'TEST'...
fatal: unable to access 'http://phabricator.local/diffusion/TEST/': The requested URL returned error: 403
```

when `policy.allow-public` is false.  After this fix I get:

```
james@james-laptop:~/git/8> git clone http://phabricator.local/diffusion/TEST/
Cloning into 'TEST'...
