MOZ_CRASH_UNSAFE_PRINTF causes data collection because crash strings are annotated to crash-stats and are publicly visible. Firefox data stewards must do data review on usages of this macro. However, all the crash strings this patch collects with MOZ_CRASH_UNSAFE_PRINTF are already collected with NS_RUNTIMEABORT.

It's a sub-class of nsAtom, useful for cases where you know you are dealing
exclusively with static atoms. The nice thing about it is that you can use
raw nsStaticAtom pointers instead of RefPtr<>. (In fact, the AddRef/Release
implementations ensure that we'll crash if we use RefPtr<nsStaticAtom>.)

We can save the entry in the hashtable, and then re-use that entry as a
starting point for removing from the hashtable, should that become
necessary. This saves us having to rehash things, at a minimum.
Right now, NS_GENERIC_FACTORY_SINGLETON_CONSTRUCTOR expects singleton
constructors to return already-addrefed raw pointers, and while it accepts
constructors that return already_AddRefed, most existing don't do so.
Meanwhile, the convention elsewhere is that a raw pointer return value is
owned by the callee, and that the caller needs to addref it if it wants to
keep its own reference to it.
The difference in convention makes it easy to leak (I've definitely caused
more than one shutdown leak this way), so it would be better if we required
the singleton getters to return an explicit already_AddRefed, which would
behave the same for all callers.
This also cleans up several singleton constructors that left a dangling
pointer to their singletons when their initialization methods failed, when
they released their references without clearing their global raw pointers.

Defining Get() in the declaration of InputEventStatistics implicitly
sticks an "inline" on the function, which is not what we want: inlining
it spreads around a lot of static initialization code. Providing an
out-of-line definition is much better in terms of code size.
It's easy to mess up the scoping so that (a) the label is pushed and then
immediately popped, and/or (b) the string doesn't live long enough. It's also
easy to do a utf16-to-utf8 conversion unnecessarily when the profiler is
inactive. This patch splits that macro into three new ones that are harder to
mess up.
- AUTO_PROFILER_LABEL_DYNAMIC_CSTR: same as current.
- AUTO_PROFILER_LABEL_DYNAMIC_NSCSTRING: for nsCStrings.
- AUTO_PROFILER_LABEL_DYNAMIC_LOSSY_NSSTRING: for nsStrings.

There are four things that must be provided for every static atom, two of which
have a macro:
- the atom pointer declaration (no macro);
- the atom pointer definition (no macro);
- the atom char buffer (NS_STATIC_ATOM_BUFFER);
- the StaticAtomSetup struct (NS_STATIC_ATOM_SETUP).
This patch introduces new macros for the first two things: NS_STATIC_ATOM_DECL
and NS_STATIC_ATOM_DEFN, and changes the arguments of the existing two macros
to make them easier to use (e.g. all the '##' concatenation now happens within
the macros).
One consequence of the change is that all static atoms must be within a class,
so the patch adds a couple of classes where necessary (DefaultAtoms, TSAtoms).
The patch also adds a big comment explaining how the macros are used, and what
their expansion looks like. This makes it a lot easier to understand how static
atoms work. Correspondingly, the patch removes some small comments scattered
around the macro use points.

In order to properly disable template functions with `std::enable_if` we need
to use the resulting type. This only works if we use a dependent type in the
template params, hence the need to shadow the `T` param.
Proper usage is now of the form:
template<typename Q = T, typename EnableIfChar = CharOnlyT<Q>>
Foo();

This change requires introducing nsID::Clone(). Because it's infallible, the
patch also removes some redundant failure-handling code. (nsMemory::Clone() is
also infallible, so this code was redundant even before this change.)

The new code is slightly less efficient because it requires measuring the
string length, but these strings are all short so it shouldn't matter.
Note that the case in DataToString() is a little different. The std::min() that
was there appears to be excessive caution -- this code is always printf'ing
some kind of number, so 32 chars should never be reached -- but it was bogus
anyway, because if 32 was exceeded then (a) we would have overflowed `buf`, and
(b) we'd be returning a non-null-terminated string.

They are equivalent -- both infallible, both requiring measuring the length of
the string -- but moz_xstrdup is much more readable. (One place deals with
16-bit strings and so uses NS_strdup instead, which is also infallible.)
The patch also removes some failure-path code that will never execute due to
the infallibility.

There should be no functional change here, but we rely upon the new
structure in the next patch in the series. This separates out the
notions of removing a request from the load group (which is always
final, and must be executed outside of synchronous calls from the owner
of the imgRequestProxy) and wanting to readd a request to the load group
as a background request (for multipart images).
The most important addition is mForceDispatchLoadGroup which if true
when imgRequestProxy::RemoveFromLoadGroup is called, will dispatch the
removal from the load group instead of executing it inline. This ensures
safety for any callers (e.g. to CancelAndForgetObserver) as above.
Currently nsAtom::mString points to the interior of an nsStringBuffer. For
static atoms this requires the use of nsFakeStringBuffer, which is pretty
gross.
This patch changes things so that nsAtom::mString points to a static char
buffer for static atoms. This simplifies a number of things:
- nsFakeStringBuffer and CheckStaticAtomSizes are no longer needed.
- FakeBufferRefCountHelper is no longer needed.
- nsAtom's constructor for static atoms is simpler.
- RegisterStaticAtoms() is simpler.
On the flip-side, a couple of things get more complicated.
- nsAtom::ToString() treats static and dynamic atoms differently.
- nsAtom::GetStringBuffer() is now only valid for dynamic atoms. This
function is only used in two places, both involving DOMString, so those
locations are updated appropriately. This also requires updating some other
code assigning nsStrings to DOMStrings, because we can't assume that
nsStrings are shared.
On Linux64 this change reduces the size of the binary by 8752 B, and moves
81968 B from the .data to the .rodata section, where it can be shared between
processes.
