Make the pepper 2D flush callback actually function as advertised. It will now

get called asynchronously when the bits are actually copied to the screen,
rather than synchronously from inside the paint function. This makes it useful
for plugins to use the callback for rate limiting. This also adds a lot of
infrastructure for running tests on pepper devices, and includes a unit test
for the new flush behavior. I made the existing RenderProcess object an
abstract interface and made the existing MockProcess (renamed to be more clear)
implement that. This avoids a static cast that would actually crash during a
unit test because some code was hardcoded to expect a RenderProcess object.
This fixes base's IDMap iterator which has apparently never been used for an
IDMap with ownership semantics.
