Bug 1682030 - Remove some dead NPAPI code from dom/plugins and related spots. r=jmathies,mconley,ipc-reviewers,mccr8 

This is the first of two patches in this series that removes a large amount of now dead code from dom/plugins as part of removing all NPAPI plugin support.  This patch removes re-entrancy guards we have for Windows OnPaint messages, as the guards were only needed for windowed plugins.

This API is used to facilitate binding code written in C to script
objects. The API in this header does not assume the presence of a
user agent. That is, it can be used to bind C code to scripting
environments outside of the context of a user agent.
However, the normal use of the this API is in the context of a
scripting environment running in a browser or other user agent.
In particular it is used to support the extended Netscape
script-ability API for plugins (NP-SAP). NP-SAP is an extension
of the Netscape plugin API. As such we have adopted the use of
the "NP" prefix for this API.
The following NP{N|P}Variables were added to the Netscape plugin
API (in npapi.h):
NPNVWindowNPObject
NPNVPluginElementNPObject
NPPVpluginScriptableNPObject
These variables are exposed through NPN_GetValue() and
NPP_GetValue() (respectively) and are used to establish the
initial binding between the user agent and native code. The DOM
objects in the user agent can be examined and manipulated using
the NPN_ functions that operate on NPObjects described in this
header.
To the extent possible the assumptions about the scripting
language used by the scripting environment have been minimized.

* InitDXGISurface to us, the content process' PluginInstanceParent (PIP).
* - The PIP uses the ImageBridge to tell the compositor to create 2
* surfaces -- one to be written to by the plugin process and another
* to be displayed by the compositor. The PIP returns the plugin
* surface to the PIC.
* - The PIC repeatedly issues ShowDirectDXGISurface calls to tell the
* PIP to blit the plugin surface to the display surface. These
* requests are forwarded to the compositor via the ImageBridge.
* - The PIC sends FinalizeDXGISurface tio the PIP when it no longer needs
* the surface. The PIP then tells the compositor to destroy the
* plugin surface. After this, the PIP will tell the compositor to
* also destroy the display surface as soon as the ImageBridge says it
* no longer needs it.

// If a plugin spins a nested glib event loop in response to a
// synchronous IPC message from the browser, the loop might break
// only after the browser responds to a request sent by the
// plugin. This can happen if a plugin uses gtk's synchronous
// copy/paste, for example. But because the browser is blocked on
// a condvar, it can't respond to the request. This situation
// isn't technically a deadlock, but the symptoms are basically
// the same from the user's perspective.
//
// We take two steps to prevent this
//
// (1) Detect nested event loops spun by the plugin. This is
// done by scheduling a glib timer event in the plugin
// process whenever the browser might block on the plugin.
// If the plugin indeed spins a nested loop, this timer event
// will fire "soon" thereafter.
//
// (2) When a nested loop is detected, deschedule the
// nested-loop-detection timer and in its place, schedule
// another timer that periodically calls back into the
// browser and spins a mini event loop. This mini event loop
// processes a handful of pending native events.
//
// Because only timer (1) or (2) (or neither) may be active at any
// point in time, we use the same member variable
// |mNestedLoopTimerId| to refer to both.
//
// When the browser no longer might be blocked on a plugin's IPC
// response, we deschedule whichever of (1) or (2) is active.
