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.

Because it's the type we use to set up static atoms at startup, not the static
atom itself.
The patch accordingly renames some parameters, variables, and NS_STATIC_ATOM,
for consistency.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This is straightforward, with only two notable things.
- `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"`
throughout, because all nsXPIDLString.h did was include nsString.h. The
exception is for files which already include nsString.h, in which case the
patch just removes the nsXPIDLString.h inclusion.
- The patch removes the |xpidl_string| gtest, but improves the |voided| test to
cover some of its ground, e.g. testing Adopt(nullptr).

These are all straightforward except for InternalLoadEvent::mTypeHint, which
requires a bit of care to preserve existing behaviour.

We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is null checked. The patch uses IsVoid() to replace
the null checks (and get() and EqualsLiteral() calls to replace any implicit
conversions).

nsXPIDLStrings are marked as VOIDED upon initialization. Most of these local
nsXPIDLString variables are immediately set via getter_Copies(), which will
either assign a string value (using Adopt()) or do SetIsVoid(). These can be
trivially converted to nsString, which will get the same treatment.
The patch suitably converts the remaining nsXPIDLString local variable as well.

These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is used in ways that rely on the implicit conversion
to |char*|. The patch uses get() and EqualsLiteral() calls to replace the
implicit conversions.
In all of these cases the fixed buffer has the same lifetime as the string
object, so we can use nsAuto[C]String for simplicity.
For the 128-length ones in dom/xul/ I just switched to the default of 64 for
simplicity, because the choice of 128 didn't seem that important. (These code
paths weren't hit when I started the browser and opened a few sites.)
Finally, the patch also changes LoggingIdString to use
nsAutoCStringN<NSID_LENGTH>, similar to NullPrincipalURI.
It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.

This replaces the usage of |PR_LogPrint| with either |printf_stderr| or
|MOZ_LOG| where appropriate. |printf_stderr| is used where a logger is not
actually available or if log levels are not being used as expected.
This is not the cleanest code ever, but we need to move all static atom
initialization prior to NS_SealStaticAtomTable to avoid the possibility
of dynamic atoms being transmuted into static atoms. We therefore need
to open up an avenue for somebody else to initialize the atoms that RDF needs.
Neither Firefox nor Thunderbird use any of rdfISerializer,
NS_RDFNTRIPLES_SERIALIZER_CID, and
"@mozilla.org/rdf/serializer;1?format=ntriples".
https://dxr.mozilla.org/addons/source/ shows three addons that use them, but
only one does so meaningfully: ArchView. (The others mention them as part of
long lists of XPCOM interfaces.) According to AMO, ArchView hasn't been updated
since August 2008, it has only 153 users, it doesn't work in Firefox 53. Also,
judging from the code, rdfISerializer is only be used as part of debugging the
addon itself. So I think that use can be ignored.
This patch removes them. It also removes rdfTriplesSerializer.cpp.
