David Anderson 0aaa659e29 Fix how the mark-serial is used.
The mark-serial is a generation number to optimize dependency tracking. It did not actually get
applied correctly, meaning that in rare cases we could miss dependencies. This patch removes the
incorrect serial propagation and ensures that we don't double-count a dependent plugin.

Additionally, this patch ensures that all callers of BindNativeToPlugin() will update the mark
serial, as is required to correctly track dependencies.
