Moved IsRefcountedSmartPointer and StripSmartPointer from ::detail to
::mozilla, to permit their use from other files.
Renamed StripSmartPointer to RemoveSmartPointer, for consistency with the
usual 'Remove...' type traits.

This marks the idl classes as deprecated, removes an unnecessary include that
was triggering deprecation warnings and wraps a necessary include in
XPCOMInit.cpp that is used for registering the component in deprecation
disabling pragmas.

Making this constructor non-explicit will permit automatic conversions from
'nullptr' into RefPtr types, which I think are not dangerous.
The one spot that this affects is in 'UserDataType nsBaseHashtable::Get(KeyType)',
which does a 'return 0;' into the UserDataType, which could be a bool, an int, a
RefPtr or other. I'm changing that into a C++11 "value initialization", which
falls back to "zero initialization" for PODs: 'return UserDataType{};'.
Also fixed the comment to clarify not-found return values, as Get(KeyType) was
not only used for pointers anyway.

The intent of idleDispatch is the possibility to have a runnable
executed when the thread is idle. This is accomplished by adding an
event queue for idle tasks that will only be considered when the main
event queue is empty and the caller of ProcessNextEvent doesn't
require that we wait until there is an event on the main event queue.

We needed this polyfill for <initializer_list> when some of our C++
standard libraries did not support said header. They all do now, so the
polyfill is redundant.
This removes the scriptable method |Compact| which is unused in

This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);

> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");

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.

This is the same basic idea as NS_IMPL_RELEASE_WITH_DESTROY. I need
this because I am making XPCNativeInterface refcounted, and it uses
some weird placement new stuff requiring a special function to
deallocate the object. (It does this to store an array of arbitrary
length inline, presumably for some sort of time or space reason.)

We have a number of nsTHashtable<nsPtrHashKey<T>> instantiations, mostly
from IPDL-generated code. There's no reason in principle that all of
these instantiations couldn't share code, since they're all storing POD
entries of the same size. Let's specialize nsTHashtable for such types,
providing a thin layer over a hashtable that stores void pointers. This
change saves about 90K of space (!) on x86-64 Linux.
The standard placement new function is declared to not throw, which
means that, per spec, a null check on its result is required. There are
a number of places throughout xpcom/ where we know that we are passing
non-null pointers to placement new (and receiving them as a return
value), and we are therefore doing useless work performing these null
checks.
Therefore, we should be using an operator new overload that doesn't
require the null check. MFBT has just such an overload, so use that.

mozilla::function involves an allocation of the FunctionImpl type, that we can
avoid rather easily in this case.
This commit is completely optional, I guess, though the code we're using
RemoveElementsBy with the previous patch is sort of hot.
