f9d909f985 screenshot: Respect lockdown settings 
We allow users/admins to lock down disk writes, respect that when
taking screenshots.

f02b007337 shell-screenshot: Only allow one screenshot request at a time per sender 
We currently allow infinite number of screenshot requests to be active at
the same time, which can "dos" the system and cause OOM.

So fail subsequent requests for the same sender when a screenshot operation
is already running.

df08ae7996 screenshot: Port to GrabHelper 
Taking an area screenshot doesn't work currently when in "grab mode",
for instance when the message tray or top bar menus are open. Fix
this by using GrabHelper for selecting the area, so grabs are properly
stacked for us.

deb2f30b37 js: Use EVENT_PROPAGATE/EVENT_STOP constants in event handlers 
Just as SOURCE_CONTINUE/SOURCE_REMOVE in source functions, these
constants increase code clarity over plain true/false.

f9f5004909 screenshot: Extend ScreenshotArea parameter validation 
We currently only ensure that width and height are positive, so it
is still possible to pass in values that don't make any sense at all
(which may even result in a crash when exceeding limits imposed by
X11).
There is nothing to screenshot outside the actual screen area, so
restrict the parameters to that.

11c2933e23 ShellGlobal: remove cursor manipulation functions 
Use the new API in MetaScreen instead, which is automatically
routed to MetaCursorTracker as appropriate.

90fae00aa6 screenshot: Immediately show the flash spot 
The "flash" effect looks awkward when it fades in and out. Real
camera have an immediate flash of light, which then seems to fade
out as our eyes readjust the rapid change in lighting.

57bd43baf3 screenshot: move to a separate interface 
Since we're breaking API already, take this as an occasion to use a
separate interface for all the screenshot-related methods. The interface
name is org.gnome.Shell.Screenshot.
Internally, move all the related code to screenshot.js.
