This annotates vsprintf-like functions with MOZ_FORMAT_PRINTF. This may
provide some minimal checking of such calls (the GCC docs say that it
checks for the string for "consistency"); but in any case shouldn't
hurt.

For people working on Rust code, compiling in debug mode (Cargo's "dev"
profile) is convenient: debug assertions are turned on, optimization is
turned off, and parallel compilation inside of rustc itself can be
used. These things make the build faster and the debugging experience
more pleasant.
To obtain that currently, one needs to --enable-debug at the Gecko
toplevel, which turns on debug assertions for the entire browser, which
makes things run unreasonably slowly. So it would be desirable to be
able to turn *off* debug mode for the entirety of the browser, but turn
on debug mode for the Rust code only.
Hence this added switch, --enable-rust-debug, which does what it
suggests and defaults to the value of --enable-debug. For our own
sanity and because we judge it a non-existent use case, we do not
support --enable-debug --disable-rust-debug.
This is the same optimization made for ThreadSafeAutoRefCnt in bug
1277709. However, nsStringBuffer uses a 32-bit reference count all the
time, so it can't easily use ThreadSafeAutoRefCnt.

This patch adds a series of fallible methods for the rust ns[C]String
bindings, as well as the `set_length` method, which is the same as the
`SetLength` method in C++. `set_length` is marked as unsafe.
The decision was made to make the fallible methods seperate from the
infallible methods, and to use seperate Rust->C++ bindings for each of
them, rather than only binding the fallible bindings, and unwrapping
them in rust-land. This is to try to match the C++ API as closely as
possible, and to ensure that the behavior matches.

This is the patch that all the others have been leading up to: by inheriting from nsTStringRepr, nsTLiteralString loses its destructor (previously suppplied by nsTSubstring).
I included an AsString() cast as an escape hatch for a few pieces of code that couldn't easily accommodate the new hierarchy, but I'm pretty pleased with how little it was necessary.

This requires some adjustment to Equals(). Previously, when you wrote:
fooString.Equals(barString + bazString)
you'd get a tuple for the operator+, which implicitly converts to nsTSubstring, which resolves into nsTSubstring::Equals(const nsTSubstring&).
Now that Equals has moved one level up:
nsTStringRepr::Equals(const nsTStringRepr&)
The compiler can't make the double-leap from nsTSubstringTuple -> nsTSubstring -> nsTStringRepr.
So I implemented this manually.

In the next patch, tuples will work on nsTStringRepr rather than nsTSubstring, so the notions of TO_SUBSTRING and substring_type are not quite right.

All nsTStringRepr methods must be const, so the mutators remain on nsTSubstring.
I left a small number of const methods on nsTSubstring, e.g. Capacity(), the rationale being that you would only be interested in this method if you intend to mutate the string.
I considered splitting up the typedefs block and leaving behind the ones related to mutation (e.g. nsWritingIterator) but I think it makes for clearer documentation to have them all in one place.

Cleanup in preparation for upcoming patches:
- By using an accessor method, nsTPromiseFlatString no longer needs to be a friend.
- The explicit uint32_t constructors are unused.
- The abstract_string_type typedef is unused (and will be potentially confusing in the next patch, so removing).
- The three-param ctor for nsTSubstring no longer needs to be public "for convenience".
- friend class nsTObsoleteAStringThunk_CharT no longer exists.

This just-so-happened to work because nobody refers to the splitter directly by name.
The added gtest doesn't actually prove that this patch fixes anything, but I figured we could use a wide string for good measure.
