The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

By using nsCOMArray::Forget, we can pass the references we hold in an
nsCOMArray directly to the XPCOM caller, without having to go through an
extra cycle of AddRef/Release calls. This way should be slightly faster
and it also results in smaller code. Notice that we don't have to worry
about removing the OOM check in the places that use Forget(), because we
were already using moz_xmalloc to allocate the outparam array, and
moz_xmalloc aborts the process on OOM, just as Forget() does.
The nsNavHistoryFolderResultNode::GetQueries change is thrown in for fun.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

rename : mfbt/nsRefPtr.h => mfbt/RefPtr.h
Doing an AddRef or Release of a cycle collected object during CC
traversal can cause leaks. traverseResultObservers does this in two
places. First, it accidentally copies the array that is passed
in. Second, the GetValue() method that is being implicitly called in
the line with |aObservers.ElementAt(i);| does a QI.
This patch fixes the former problem by passing a reference. It fixes
the latter problem by returning the raw underlying pointer held by the
nsMaybeWeakPtrArray, which is what the CC wants anyways, because it
does not care about weak referents.
Calling QueryInterface with a statically known IID should typically not
be necessary. In those cases where it's not, the compiler can do the
cast for us, though we have to supply the reference-counting that
QueryInterface would do.
In passing, several redundant null-checks for the result of |new T| have
been deleted.
