There are a few mentions of nsRuleNode left but they are mostly
historical references so it makes sense to keep them.

GetPathFromURI() result is stored in an nsAutoCString, so it might as well return that type.

`result` may be empty or may be arbitrarily long, so I'll use nsCString inside the function.

Returning an UniquePtr, will remove std::move().
Also will `return s` instead of `return nullptr` when `(!s)`, to avoid extra construction which could also prevent elision (not entirely sure, but it's at least not worse!); and it's clearer that the two `return`s return the same already-constructed on-stack object.

nsAuto{,C}String -> ns{,C}String, will add std::move().
This allowed removals of 'AllowCompilerWarnings' from layout/painting,
netwerk/cookie, and toolkit/components/extensions.

This function uses a nsAutoString internally, and its caller stores its
returned value in a nsAutoString. So it's silly for us to have it return a
different type (nsString). With this change, the compiler should be able to
perform return value optimization and avoid the need for any
copying/reallocation of this function's return value.

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.

This commit adds the ability to create a different kind of DrawTargetCapture which
has a limit on the size of which its CaptureCommandList can grow before it is
synchronously flushed to its destination DrawTarget.
Special care is taken to not do a sync flush until we would need to resize
the backing store of the CaptureCommandList. This allows us to not waste
memory we've already allocated.
The async painting content clients are updated to use it, and get a default
value from a new preference.

This introduces the machinery needed to generate crash annotations from a YAML
file. The relevant C++ functions are updated to take a typed enum. JavaScript
calls are unaffected but they will throw if the string argument does not
correspond to one of the known entries in the C++ enum. The existing whitelists
and blacklists of annotations are also generated from the YAML file and all
duplicate code related to them has been consolidated. Once written out to the
.extra file the annotations are converted in string form and are no different
than the existing ones.
All existing annotations have been included in the list (and some obsolete ones
have been removed) and all call sites have been updated including tests where
appropriate.
