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).

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).

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.

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.

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.

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.

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.
