The current code is somewhat non-obvious to a first-time reader, and
OS_TEST is a bizarre thing anyway, since it's actually the name of the
CPU we're running on. We'd do well to minimize the use of OS_TEST.
Note that the complete nuking of the xptcall/md/unix/moz.build lines are
because we don't support OS X/x86 anymore.
In order to avoid the overhead of doing a full pref lookup for every static
var cache at content process startup, we currently assume that the default
value of any static varcache pref will always match the default value of its
database entry (as long as the pref isn't locked). This lets us only perform
lookups for preferences which have a user value, or are locked.
If the default values of those preferences are changed in a bundled preference
file, though, the varcache value will be correct in the parent process, but
not in child processes. Since this is an easy mistake to make, we should
assert that it doesn't happen.
Note: This change only affects applications which use e10s. Applications like
Thunderbird can still override default values of any static pref with
impunity. Repacks and distributors can only do so by changing user values or
locking the preference after the change (which is the standard practice for
enterprise deployments).

Pending figuring out how we want to block autoplay of WebAudio content, we
should just not block it by default for the initial release of block autoplay,
and follow up once we've figured out how to not break the web.

The prefs, when enabled, will dump the gecko DL items followed by the
WR DL items that were generated from that gecko item. This allows us to
easily go from a DOM element with known id/class attributes to e.g. an
ImageKey of an image that was generated for that element.
Also, this logging can be enabled in CI builds just like gecko display-list
dumping, instead of the ifdef that we previously had in WebRenderLayerManager.
