Fixes the location of the dummy window, cleans up some duplicate window-handling code, and tries to keep the window activation status more in sync with what it would be in a single-process system. The net result is that event handling in plugins works better, although there are still activation issues.
BUG=none
TEST=Clicks on plugins should register in the right place (assuming they register at all; there are still bugs in having them handled).

This listens to tab events and tries to keep thumbnails ready to go. See
thumbnail_generator.cc for a more detailed design.
This adds a painting observer to the RenderWidgetHost to enable this new
behavior, as well as a notification to allow the thumbnail generator to hook
its observer in. There is also a new notification that a backing store has been
disabled, which required making the backing stores know about their owning
widget hosts.
This component is currently disabled. We just need to uncomment the member in
Profile and it will start to work.

This patch reworks bitmap transport on all platforms. Linux and Mac
are switched from serialising bitmaps over the IPC channel to using
shared memory. All platforms gain a shared memory mapping cache on the
host side.
The concept of a TransportDIB (device independent bitmap) is added to
encapsulate most of the platform specifics.
On Linux, we use SysV shared memory. This is because X shared pixmaps,
which predate POSIX SHM, can only use SysV. By using SysV between
renderer and browser, we open up the possibility to map the shared
memory directly from the renderer to the X server.
On Mac, we use POSIX shared memory. However, since this needs
filesystem access and the Mac renderer is sandboxed from the
filesystem, we add two new messages from renderer -> browser:
The first, AllocTransportDIB, synchronously creates a transport DIB in
the browser and passes a handle back to the renderer. The second,
FreeTransportDIB, asynchronously, notifies the browser that it may
close its handle to the shared memory region.
On Mac, the shared memory regions are identified by their inode
numbers on the wire. This means that the browser must keep handles
open to all the allocated shared memory regions (since an inode number
is insufficient to map the region). The alternative design is that the
renderer passes the file descriptor with each paint operation. Since
passing file descriptors is special case in the code, I felt that it
would be best to minimise their use. Creating and freeing transport
DIBs are relatively rare operations relative to paints and scrolls.
On Windows, most of the code remains the same, except that Windows now
uses the mapping cache added in this patch. This allows the browser to
maintain a shared memory mapping for a transport DIB over several
paints. Previously it mapped and unmapped for every operation, causing
lots of TLB and VM churn.
