This allows a bunch of other things to be removed too, including
PluginModuleParent::mSurrogateInstances,
PluginModuleChromeParent::sInstantiated, and NS_PLUGIN_INIT_PENDING.
The patch also removes the AsyncPluginInit crash annotation.
This changes CrashReporterHost::GenerateMinidumpAndPair() and up the caller chain to use callbacks so we
may call it synchronously or asynchronously.

The old code would do the content process portion of the open by
immediately sending a message back to the content process, but this
has some weird issues with nesting and priorities. Instead of doing
that, I return the endpoint for the content process back to the
original sync call. This requires more code changes, to thread the
endpoint along, but it is conceptually simpler.
Once I removed the bridges and got it working, I was just able to
remove the spawns from the IPDL file and it worked.

mContentParent is really just to be used while handling a synchronous
ContentParent::RecvLoadPlugin call when async plugin init turned on.
In any other context, using it will be unsafe.
This patch adds comments and assertions to ensure that this value isn't set
otherwise, and converts the one use of mContentParent outside of async plugin
init to use an alternative mechanism for identifying the content process.

Normally, this could be served by the process ID of a plugin, however, run ID is meant
to be consumed by multi-process browser chrome code for telling different runs of a
plugin apart (for example, for searching the DOM for a crashed instance of a plugin,
while ensuring that we don't accidentally find newly spawned instances that have not
crashed). Exposing something as low-level as the process ID to browser chrome code
seemed like Too Much Information. Also, there is the extremely unlikely chance that
a process ID might be re-used immediately after the original process shuts down. This
run ID avoids that case, regardless of how unlikely.
This patch has a few side effects:
1. Plugins in the chrome process are "mirrored" to all content processes,
although this mirroring is currently imperfect (bug 1090576)
2. Plugins are no longer sorted by modification date in nsPluginHost.
3. Plugin exceptions are no longer propagated to JS code. They are ignored.
