This removes a lot of the plumbing for having the platform embed itself
through IPC which was required for B2G running the browser as both
shell and browser application.
Vim control lines were re-introduced or not entirely cleaned up.
This nukes them again.
Removing from modules, netwerk, security, storage, testing, toolkit, and
a few scattered misc files. More to come.
This creates a number of stubs and leaves some surrounding code that may be irrelevant (eg. recorded time stamps, status variables).
Stub resolution/removal should be a follow-up to this.
