It is replaced by a standard-conforming cast to (void) which is
understood the same by the compiler.
In some cases this could be replaced by `[[maybe_unused]]` but for
expression whose value is ignored, this requires storing to a temporary
variable first, so not going that way.
One notable change is that marking an object of type already_AddRefed as
unused used to implicitly leak memory. This is now made explicit.
Most of the heavy lifting was done through:
$ git grep -l '\<Unused\> <<' | xargs sed -i -e 's/Unused << /(void)/g'
$ git grep -l mozilla/Unused.h | xargs sed -i -e '/mozilla\/Unused.h/ d'

This matches the behavior of other browsers, and avoids having to keep
alive the link element and thus associated document etc for too long.

`SharedSubResourceCacheLoadingValueBase` define the `mIsCancelled` field which
is overloaded by `SheetLoadData`. This patch moves all fields including
`mIsLoading` to `SheetLoadData` and add accessors to access these fields.

This moves the style-specific bits of the shared style sheet cache into
a super-class, and leaves the generic "sub-resource management" bits
inside a base class. In order to implement it you need to provide some
types, mainly:
* Loader, which implements LoaderPrincipal() and allows you to key per
principal. The idea is that this would be the
{CSS,Script,Image}Loader object.
* Key (self explanatory). We might want to introduce a common key to
share the cache partitioning logic.
* Value, which represents the final cached value. This is expected to
be a StyleSheet / Stencil / imgRequestProxy.
* LoadingValue, which must inherit from
SharedSubResourceCacheLoadingValueBase (which contains the linked
list and the state that the cache manages). It also must provide a
ValueForCache() and ExpirationTime() members. For style, this is the
SheetLoadData. For script this will probably be the
ScriptLoadRequest. For images it might be enough with the
imgRequestProxy, but we might need something else, haven't looked
into it too deeply yet.
We move the use counters into the stylesheet since that's both more
similar to how we treat StyleSheetContents and easier (that way we don't
need to add some sort of "extra data" thing to the cache).

With a very simple tweak to SheetLoadDataHashKey::KeyEquals we should
get the same kind of caching but in a much simpler way.

This fixes a leak that my previous patch uncovers. See comment 9 for the
diagnostic, I had missed mRequestingNode in comment 10.
The observer change is not technically necessary but since observers can
theoretically keep alive random stuff as well, clean them up as well.
In particular, clear mOwningNode after we've fired load / error events
(which is what we need it for), and mRequestingNode once we call
LoadComplete, where it is no longer useful.
