Summary:
Ref T2625. Ref T3794. Ref T418. Ref T1703.
This is a more general version of D5278. It expands CustomField support to include real integration with ApplicationSearch.
Broadly, custom fields may elect to:
- build indicies when objects are updated;
- populate ApplicationSearch forms with new controls;
- read inputs entered into those controls out of the request; and
- apply constraints to search queries.
Some utility/helper stuff is provided to make this easier. This part could be cleaner, but seems reasonable for a first cut. In particular, the Query and SearchEngine must manually call all the hooks right now instead of everything happening magically. I think that's fine for the moment; they're pretty easy to get right.
Test Plan:
I added a new searchable "Company" field to People:
{F58229}
This also cleaned up the disable/reorder view a little bit:
{F58230}
As it did before, this field appears on the edit screen:
{F58231}
However, because it has `search`, it also appears on the search screen:
{F58232}
When queried, it returns the expected results:
{F58233}
And the actually good bit of all this is that the query can take advantage of indexes:
mysql> explain SELECT * FROM `user` user JOIN `user_customfieldstringindex` `appsearch_0` ON `appsearch_0`.objectPHID = user.phid AND `appsearch_0`.indexKey = 'mk3Ndy476ge6' AND `appsearch_0`.indexValue IN ('phacility') ORDER BY user.id DESC LIMIT 101;

Fixes T3810. In PhabricatorPeopleQuery, we issue an unnecessary query like this:
SELECT f.* FROM file f WHERE (f.phid IN ('')) ORDER BY f.id DESC
...if we're loading a user without a profile picture. Filter the file PHIDs before loading them to prevent this.
This doesn't change anything, but saves us a spurious/silly query.
Also makes `PhabricatorPeopleProfileController` use `needProfileImage()`, moving us closer to getting rid of `loadProfileImageURI()` eventually.

Summary:
Ref T1702. Ref T3718. There are a couple of things going on here:
**PhabricatorCustomFieldList**: I added `PhabricatorCustomFieldList`, which is just a convenience class for dealing with lists of fields. Often, current field code does something like this inline in a Controller:
foreach ($fields as $field) {
// do some junk
}
Often, that junk has some slightly subtle implications. Move all of it to `$list->doSomeJunk()` methods (like `appendFieldsToForm()`, `loadFieldsFromStorage()`) to reduce code duplication and prevent errors. This additionally moves an existing list-convenience method there, out of `PhabricatorPropertyListView`.
**PhabricatorUserConfiguredCustomFieldStorage**: Adds `PhabricatorUserConfiguredCustomFieldStorage` for storing custom field data (like "ICQ Handle", "Phone Number", "Desk", "Favorite Flower", etc).
**Configuration-Driven Custom Fields**: Previously, I was thinking about doing these with interfaces, but as I thought about it more I started to dislike that approach. Instead, I built proxies into `PhabricatorCustomField`. Basically, this means that fields (like a custom, configuration-driven "Favorite Flower" field) can just use some other Field to actually provide their implementation (like a "standard" field which knows how to render text areas). The previous approach would have involed subclasssing the "standard" field and implementing an interface, but that would mean that every application would have at least two "base" fields and generally just seemed bleh as I worked through it.
The cost of this approach is that we need a bunch of `proxy` junk in the base class, but that's a one-time cost and I think it simplifies all the implementations and makes them a lot less magical (e.g., all of the custom fields now extend the right base field classes).
**Fixed Some Bugs**: Some of this code hadn't really been run yet and had minor bugs.

If a PhabricatorActionItem is a workflow and there is no user OR the user is logged out, we used this objectURI to construct a log in URI.
Potentially added some undesirable behavior to aggressively setUser (and later setObjectURI) from within the List on Actions... This should be okay-ish unless there was a vision of actions having different user objects associated with them. I think this is a safe assumption.

This adds:
- A provider-driven "start" screen (this has the list of ways you can login/register).
- Registration actually works.
- Facebook OAuth works.
@chad, do you have any design ideas on the start screen? I think we poked at it before, but the big issue was that there were a limitless number of providers. Today, we have:
- Password
- LDAP
- Facebook
- GitHub
- Phabricator
- Disqus
- Google
We plan to add:
- Asana
- An arbitrary number of additional instances of Phabricator
Users want to add:
- OpenID
- Custom providers
And I'd like to have these at some point:
- Stripe
- WePay
- Amazon
- Bitbucket
So basically any UI for this has to accommodate 300 zillion auth options. I don't think we need to solve any UX problems here (realistically, installs enable 1-2 auth options and users don't actually face an overwhelming number of choices) but making the login forms less ugly would be nice. No combination of prebuilt elements seems to look very good for this use case.

Summary:
Currently, registration and authentication are pretty messy. Two concrete problems:
- The `PhabricatorLDAPRegistrationController` and `PhabricatorOAuthDefaultRegistrationController` controllers are giant copy/pastes of one another. This is really bad.
- We can't practically implement OpenID because we can't reissue the authentication request.
Additionally, the OAuth registration controller can be replaced wholesale by config, which is a huge API surface area and a giant mess.
Broadly, the problem right now is that registration does too much: we hand it some set of indirect credentials (like OAuth tokens) and expect it to take those the entire way to a registered user. Instead, break registration into smaller steps:
- User authenticates with remote service.
- Phabricator pulls information (remote account ID, username, email, real name, profile picture, etc) from the remote service and saves it as `PhabricatorUserCredentials`.
- Phabricator hands the `PhabricatorUserCredentials` to the registration form, which is agnostic about where they originate from: it can process LDAP credentials, OAuth credentials, plain old email credentials, HTTP basic auth credentials, etc.
This doesn't do anything yet -- there is no way to create credentials objects (and no storage patch), but I wanted to get any initial feedback, especially about the event call for T2394. In particular, I think the implementation would look something like this:
$profile = $event->getValue('profile')
$username = $profile->getDefaultUsername();
$is_employee = is_this_a_facebook_employee($username);
if (!$is_employee) {
throw new Exception("You are not employed at Facebook.");
}
$fbid = get_fbid_for_facebook_username($username);
$profile->setDefaultEmail($fbid);
$profile->setCanEditUsername(false);
$profile->setCanEditEmail(false);
$profile->setCanEditRealName(false);
$profile->setShouldVerifyEmail(true);
Seem reasonable?
