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historical references so it makes sense to keep them.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.

* Avoid writing past an XPCOM string's length using BeginWriting().
* Instead of having a constant for max path length, query the
Windows API for the length it wants.
* Avoid using AppendPrintf for mere concatenation using arguments
that might contain non-ASCII.

We will generate a FontVariation type from the the bindings. This has the same name
as the type from 'gfx'. They're structurally the same but having them both around
confuses the compiler.
Doing std::move when returning/assigning a local or temporary object is
preventing the compiler from performing copy elision.
