Replace the boolean pref "security.sandbox.mac.flash.enabled"
with "dom.ipc.plugins.sandbox-level.flash" to support sandbox
levels and be consistent with the Windows pref name.
Adds filesystem read access to the sandbox using sandbox extensions
granted by the file dialog machinery (level 1).
Add support for level 2 which blocks read access.
Allow the sandbox to be disabled with MOZ_DISABLE_NPAPI_SANDBOX.

Remove access to DARWIN_USER_CACHE_DIR. Limit DARWIN_USER_TEMP_DIR
access to the FlashTmp subdirectory. Remove xattr read access to
~/Library/Caches/ and ~/Library/Preferences.

RenderDoc, a graphics debugging tool, uses a preload library that
creates a listening socket (Internet-domain) early in startup and
accepts connections from the frontend. If it's detected (via env vars),
we allow accept/accept4 (but not socket/bind/listen), and remain in
the parent process's network namespace so that other processes can
connect to the socket.
This doesn't change the sandbox policy if not running under RenderDoc.

This is to support WebGL with hybrid graphics drivers that connect to
a secondary X server for GL (Primus and VirtualGL), without allowing
access to arbitrary sockets. In addition to local X11 connections,
Primus needs to connect to the Bumblebee daemon (otherwise it will exit
the calling process).
The broker support is limited to AF_UNIX, to non-datagram sockets (see
bug 1066750), and to pathname addresses. Abstract addresses could
theoretically be handled but there isn't currently a compelling reason
to, and the broker very much assumes it's dealing with a C-style string
referring to a filesystem path and not an arbitrary byte sequence
(including NULs).
At a higher level: If the GPU X server is remote then it won't work,
but it won't work anyway because WebGL requires features that aren't
supported by indirect GLX. If the GPU X server is local but the browser
is inside a chroot, it will fail to connect unless /tmp/.X11-unix is
bind-mounted into the chroot; hopefully this use case is not common.

The SandboxLaunchPrepare currently bails out early if it detects a
lack of user namespaces. Hoist the check for drivers needing SysV
IPC up so it's done before that early exit, and the required env
variables get correctly set.
With this we no longer fail with a SIGSYS sandbox error, though
in a debug build we still crash because many assumptions in the
graphics stack get broken when that fails to initialize the driver
for WebGL.
