Extracts out the creation of an NSEvent from a WidgetKeyEvent in
TextInputHandler.mm into generic helper method. The helper is used by headless
to create a fake NSEvent to then build edit commands from key events.

Many tests rely on the minimum size of widgets to
be set. Also, the precise size seems to matter for some
tests that have hard coded offsets.

This fixes a series of issues uncovered by the Web Platform Tests.
The most immediately noticeable symptom was that, during shutdown, PuppetWidgets
on the client side attempted to delete shadow layers that were never created on
the compositor side. The usage of BasicLayerManager in all other widgets due to
headless mode meant that the PLayerTransactionParent was never initialized with
a layer manager, and thus discarded all transaction messages it received but not
delete layer messages.
The effects of only using BasicLayerManager in headless mode also showed up in
the web platform reftests, which ended up as blank white boxes in e10s mode as
the compositor thread never received paint instructions. Switching over to
using ClientLayerManager in headless mode causes these paint instructions to be
relayed.
In order to make ClientLayerManager work under headless mode, it was necessary
to implement a HeadlessCompositorWidget and hook that up to the CompositorWidget
creation function in widget/gtk. A follow-up patch will be necessary to hook up
the same for the other supported widget platforms.

Full Firefox on Linux can now be run with a --headless flag.
This includes seven parts:
1) Running all marionette tests in headless mode.
2) Prevents crashes where Firefox calls into GTK.
3) Adds a headless screen helper which supports changing the headless
screen size with the environment variables MOZ_HEADLESS_WIDTH and
MOZ_HEADLESS_HEIGHT.
4) Supports simulating moving a headless window.
5) Adds a stubbed out nsSound implementation.
6) Supports simulating size mode changes of headless windows.
7) Adds the --headless flag for Firefox.
Supports creating a windowless browser on Linux without an X server. Most of the
changes are just adding branches to avoid calls in to GTK which calls
into X. Some of the bigger additions were adding a separate headless widget
which implements just enough to render a page. A headless look and
feel were also added since there are many calls into GTK in the platform
specific one.
