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 LICENSE file and that it didn't modify externals.

Summary:
- Add getHelpURI() to PhabricatorApplication for application user guides.
- Add a new "help" icon menu item and skeletal Diviner application.
- Move help tabs to Applications where they exist, document the other ones that don't exist yet.
- Grep for all tab-related stuff and delete it.
Test Plan: Clicked "help" for some apps. Clicked around randomly in a bunch of other apps.

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.
Test Plan: Browsed around various affected tools; any issues here should throw/fail in a loud/obvious way.

- Adds a full synchronous mode for debugging.
- Adds some logging.
- It can now allocate EC2 machines and put webroots on them in a hacky, terrible way.
- Adds a base query class.

Summary:
Rough cut of Drydock. This is very basic and doesn't do much of use yet (it
//does// allocate EC2 machines as host resources and expose interfaces to them),
but I think the overall structure is more or less reasonable.
== Interfaces
Vision: Applications interact with Drydock resources through DrydockInterfaces,
like **command**, **filesystem** and **httpd** interfaces. Each interface allows
applications to perform some kind of operation on the resource, like executing
commands, reading/writing files, or configuring a web server. Interfaces have a
concrete, specific API:
// Filesystem Interface
$fs = $lease->getInterface('filesystem'); // Constants, some day?
$fs->writeFile('index.html', 'hello world!');
// Command Interface
$cmd = $lease->getInterface('command');
echo $cmd->execx('uptime');
// HTTPD Interface
$httpd = $lease->getInterface('httpd');
$httpd->restart();
Interfaces are mostly just stock, although installs might add new interfaces if
they expose different ways to interact with resources (for instance, a resource
might want to expose a new 'MongoDB' interface or whatever).
Currently: We have like part of a command interface.
== Leases
Vision: Leases keep track of which resources are in use, and what they're being
used for. They allow us to know when we need to allocate more resources (too
many sandcastles on the existing hosts, e.g.) and when we can release resources
(because they are no longer being used). They also give applications something
to hold while resources are being allocated.
// EXAMPLE: How this should work some day.
$allocator = new DrydockAllocator();
$allocator->setResourceType('sandcastle');
$allocator->setAttributes(
array(
'diffID' => $diff->getID(),
));
$lease = $allocator->allocate();
$diff->setSandcastleLeaseID($lease->getID());
// ...
if ($lease->getStatus() == DrydockLeaseStatus::STATUS_ACTIVE) {
$sandcastle_link = $lease->getInterface('httpd')->getURI('/');
} else {
$sandcastle_link = 'Still building your sandcastle...';
}
echo "Sandcastle for this diff: ".$sandcastle_link;
// EXAMPLE: How this actually works now.
$allocator = new DrydockAllocator();
$allocator->setResourceType('host');
// NOTE: Allocation is currently synchronous but will be task-driven soon.
$lease = $allocator->allocate();
Leases are completely stock, installs will not define new lease types.
Currently: Leases exist and work but are very very basic.
== Resources
Vision: Resources represent some actual thing we've put somewhere, whether it's
a host, a block of storage, a webroot, or whatever else. Applications interact
through resources by acquiring leases to them, and then getting interfaces
through these leases. The lease acquisition process has a side effect of
allocating new resources if a lease can't be acquired on existing resources
(e.g., the application wants storage but all storage resources are full) and
things are configured to autoscale.
Resources may themselves acquire leases in order to allocate. For instance, a
storage resource might first acquire a lease to a host resource. A 'test
scaffold' resource might lease a storage resource and a mysql resource.
Not all resources are auto-allocate: the entry-level version of Drydock is that
you manually allocate a couple boxes and configure them through the web console.
Then, e.g., 'storage' / 'webroot' resources allocate on top of them, but the
host pool itself does not autoscale.
Resources are completely stock, they are abstract shells representing any
arbitrary thing.
Currently: Resource exist ('host' only) but are very very basic.
== Blueprints
Vision: Blueprints contain instructions for building interfaces to, (possibly)
allocating, updating, managing, and destroying a specific type of resource in a
specific location. One way to think of them is that they are scripts for
creating and deleting resources. For example, the LocalHost, RemoteHost and
EC2Host blueprints can all manage 'host' resources.
Eventually, we will support more types of resources (storage, webroot,
sandcastle, test scaffold, phacility deployment) and more providers for resource
types, some of which will be in the Phabricator mainline and some of which will
be custom.
Blueprints are very custom and specific to application types, so installs will
define new blueprints if they are making significant use of Drydock.
Currently: They exist but have few capabilities. The stock blueprints do nearly
nothing useful. There is a technically functional blueprint for host allocation
in EC2.
== Allocator
This is just the actual code to execute the lease acquisition process.
Test Plan: Ran "drydock_control.php" script, it allocated a machine in EC2,
acquired a lease on it, interfaced with it, and then released the lease. Ran it
again, got a fresh lease on the existing resource.
