This version of the patch hopefully causes fewer performance regressions.
It might be good to apply this and catch some more assertions.

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.

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();

(patch is actually r=erahm,mystor)
nsTFixedString<T> is only used as a base class for nsTAutoStringN<T, N>, so
this patch merges the former into the latter, cutting some code and simplifying
the string class hierarchy.
Because the "Fixed" name is now gone, the patch also renames
StringDataFlags::FIXED as INLINE and ClassDataFlags::FIXED as INLINE.
The patch also removes nsFixed[C]String and ns_auto_[c]string! from Rust code
because nsAutoString can't be implemented directly in Rust due to its move
semantics. There were only two uses of ns_auto_string! outside of tests so this
seems like a minor loss.

XPCOM's string API doesn't have the notion of a "null string". But it does have
the notion of a "void string" (or "voided string"), and that's what these
functions are returning. So the names should reflect that.

Bug 1388789 introduced a bug breaking formats like "%*.f". The problem
was that the next "natural" argument was taken before the "*" width
argument.

nsTextFormatter unconditionally emitted a trailing \0, leading some code
elsewhere to have to work around this. This changes the code to only
emit it in snprintf.

Change nsTextFormatter functions to template functions, box their
arguments, and then make the formatter mostly impervious to type
mismatches. Most formatting is done according to the type of the actual
argument.

nsTextFormatter::vsnprintf is defined to return uint32_t(-1) on error.
However, it was not doing this.
nsTextFormatter::vssprintf is defined as infallible; enforce this by
having it return void.

nsTextFormatter tried to pass unrecognized escapes in the format string
through to the output. However, if the format held a width or
precision, that text was not output. It seems better to me to try to
preserve the format text as-is.

The template declaration and definition of Compare use NS_FASTCALL,
while the explicit instantiation of Compare does not, which produces
complaints from newer compilers. Add NS_FASTCALL to the explicit
instantiation so that things match up.
nsTSubstring.cpp is calling RoundUpPow2 which is defined in MathAlgorithms.h.

solution.

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

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.
This patch parameterizes nsAuto[C]String, renames them as nsAuto[C]StringN, and
redefines nsAuto[C]String as typedefs for nsAuto[C]StringN<64>.
(The alternative would be to templatize nsAuto[C]String and use a default
parameter, but that would require writing "nsAuto[C]String<>" everywhere.)
This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.
The patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.
