Bug 829557 - Part 1: When calling into plugin code, identify situations where it is safe (or unsafe) to reenter Gecko from plugin code. r=bsmedberg, a=akeybl

When Gecko is reentered from unsafe call sites, we allow the reentry, but we
suppress execution of the refresh driver to minimize the danger.
In this patch, we treat all sites as unsafe.
Bug 829557. Part 2: Allow plugin code to reenter Gecko safely while while the plugin is processing an input event. r=bsmedberg, a=akeybl

When nsPluginInstanceOwner passes input events to the plugin instance,
it's safe to reenter Gecko from plugin code and do anything, even
arbitrary script execution.
