This is just a mechanical removal. No logic changes
beyond removing the PaintPhaseSelection checks.
Most of these are just early returns to avoid doing
unnecessary work if we're only painting selections.
But now that we paint selections during the foreground
paint phase, we no longer need the early returns since
we're going to paint everything anyways.

After this CL, we first convert from mojo::Event to blink::WebInputEvent before
feeding the event to the gesture recognizer. That means we process touch and
mouse events in the same way (because they are both represented as pointer
events). As a result, we now recognize scroll and fling gestures from mice.

In order to have a high-quality gesture system, we need to know many details
about the fine-grained structure of applications. For example, different parts
of the view might be interested in recognizing different gestures and when you
recognize a certain gesture depends on the set of possible gestures.

This CL is a first step towards implementing
https://github.com/domokit/mojo/blob/master/sky/specs/gestures.md by moving the
gesture recognition into Sky where finer-grained information will be available.

In this CL, the event handler keeps track of the delta from the previous
pointer position so authors don't have to.

Before we start adding more uses of mojo app ids we should use
to a non-broken hash function. :)

What was holding me back before was I wasn't aware of us having an
incremental hash api other than base/md5.h (others in base only operate
on the full input data), however it turns out that the crypto/ library
has one in crypto/secure_hash.h.

Already other applications use sky's simple window
manager (mojo:sky_debugger) as a full-screen window
manager.  This moves this to /services and removes
all sky references from it.

As a part of this I've removed inspector support
from skydb.  It was already broken and will need
to be re-thought to not involve calls into
this new window manager.

I'm also flipping the relationship between prompt.cc
and debugger.cc for skydb.  Skydb will tell mojo_shell
to start sky_debugger_prompt instead of sky_debugger.

I'm also renaming sky_debugger_prompt to be
sky_debugger.

In Sky we only need the localName of an element to describe
what it is. Remove this abstraction which is just a thin wrapper
around AtomicString.

These appear to have been for ensuring that you
only paint elements in a given subtree. It's not clear
to me exactly how you get to painting an element that
is not rooted at the RenderLayer you started with.
I think it's just not possible in Sky anymore.
This code was added in 2004 for drag images, which
we no longer support.

HTMLIFrameElement was adding the observer in navigateView. If the same
HTMLIFrameElement navigated multiple times HTMLIFrameElement would
attach itself as an observer more than once. ObserverList doesn't like
this.

Also adds src as an attribute of HTMLIFrameElement so that I can do:
iframe.src = xxx
in script

This fixes the race which is seen where mojo_shell will sometimes
launch with the wrong viewport metrics since the DisplayManager
will happily respond to GetViewportMetrics with default values
before the NativeViewport has fully booted and told it what the
actual values are.

I considered making DisplayManager hang until the NativeViewport
was ready, but I decided that it does make sense for the
ViewportMetrics (device pixel ratio, mostly) to change for a
view if it were to move between displays (as exists on desktop
OSes today).

Mostly just mechanical changes. The one surprising bit
is that RenderLayer no longer needs to explictly paint
outlines. I tested manually that before this patch,
the paintOutline call in RenderLayer was needed for
outlines on positioned elements and that after this
patch it's not.

This CL simplifies the sky_server to only map the build directory into /gen,
which will make the deploy script simpler. This CL updates all the imports to
use the /gen prefix when referring to generated files.

I also fixed skydb to use --args-for sky_debugger to
automatically issue the load from 'start' even when
the --gdb option is present.

I tried to invoke gdb_attach directly from within start_command
but that seemed to cause some strangeness with my zsh shell
where it would automatically suspend gdb.  So I'll revisit
that change in the next patch.

The semantics of requestAnimationFrame and scheduleVisualUpdate are slightly
different. If you're inside a requestAnimationFrame, then calling
requestAnimationFrame should schedule you for next frame. However, if you're
inside a requestAnimationFrame and you scheduleVisualUpdate, that's a noop
because we've already got a visual update pending. When we merge the codepaths,
we broke requestAnimationFrame because it became a noop when called inside a
request animation frame.

We really ought to split up the two roles of requestAnimationFrame (run before
the frame boundary and run once per frame).
