Jed Davis ba1cc023b7 Bug 1151607 - Step 2: Apply net/ipc namespace separation and chroot to media plugins. r=kang
This needs more unit tests for the various pieces of what's going on
here (LinuxCapabilities, SandboxChroot, UnshareUserNamespace()) but
that's nontrivial due to needing a single-threaded process -- and
currently they can't be run on Mozilla's CI anyway due to needing user
namespaces, and local testing can just try using GMP and manually
inspecting the child process.  So that will be a followup.
