The seccomp-bpf policy is currently just the "common" policy with no
additions (but with the fixes in bug 1511560 to enable shared memory
creation). The file broker policy allows shared memory creation and
nothing else. The namespace setup is the same as for GMP (i.e., as
restrictive as we currently can be).
The sandbox can be turned off for troubleshooting by setting the
environment variable MOZ_DISABLE_RDD_SANDBOX, similarly to the other
process types.
Tested against https://demo.bitmovin.com/public/firefox/av1/ with the
necessary prefs set.

File descriptors are sometimes dup()ed in the process of communicating
them over IPC; some of this may be unnecessary (due to insufficient
use of move-only types), but dup() is relatively harmless. It was
previously allowed for both content and GMP, so this doesn't change
anything.
The handling of ftruncate is a little complicated -- it's used for IPC
shared memory, but only when creating segments; so GMP doesn't allow
it and should continue not allowing it, but content needs it and RDD
will as well. As a result, the subclass indicates if it will be needed.
Note that even when we have memfd_create support (bug 1440203),
ftruncate is still necessary even though brokering may not.

This will allow other policies to use brokering if needed (e.g., RDD and

ContentSandboxPolicy currently allows direct filesystem access if it
isn't given a broker client; this is a legacy design from the B2G era,
before the current idea of "sandbox level". With this patch, it allows
filesystem access at level 1, and above that it requires brokering.
This is both to reduce the opportunities for accidentally having a
too-permissive sandbox and to prepare for refactoring the broker glue in
bug 1511560.

Level 1 is meant to enable some seccomp-bpf filtering, but still allow
direct access to the filesystem, and level 2 is where brokering starts.
This was accidentally broken in 1365257 (making "level 1" act like level
2); this patch fixes that.
This feature obviously isn't used much given how long nobody noticed it was
broken, but it's useful to have around for troubleshooting, and it's
actually easier to fix it than edit it out of the documentation.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.
