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.

This removes the final usages of nsISupportsArray from RDF. An unused
nsCOMPtr<nsISupportsArray> is removed and another is converted to an nsCOMArray
instead.

This converts the usage of nsISupportsArray in nsIRDFDataSource to just
nsISupports. Internally none of the params are used, all external usages in
the addons repo appear to just be passthroughs.
Regardless, any external implementors wanting to pass in an nsISupportsArray
can still do so as it is derived from nsISupports.
Additionally the |IsCommandEnabled| and |DoCommand| stubs are updated to just
return NS_ERROR_NOT_IMPLEMENTED as this functionallity is currently not
supported.

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 function is an infallible alternative to nsIURI::GetSpec(). It's useful
when it's appropriate to handle a GetSpec() failure with a failure string, e.g.
for log/warning/error messages. It allows code like this:
nsAutoCString spec;
uri->GetSpec(spec);
printf("uri: %s", spec.get());
to be changed to this:
printf("uri: %s", uri->GetSpecOrDefault().get());
This introduces a slight behavioural change. Previously, if GetSpec() failed,
an empty string would be used here. Now, "[nsIURI::GetSpec failed]" will be
produced instead. In most cases this failure string will make for a clearer
log/warning/error message than the empty string.

Bug 1297961 (part 1b) - More GetSpecOrDefault() additions. r=hurley.
I will fold this into part 1 before landing.
