Bug 1400459 (part 2) - Devirtualize nsIAtom. r=heycam. This patch merges nsAtom into nsIAtom. For the moment, both names can be used interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping the use of NS_IMETHOD_. It also removes nsIAtom's IIDs. These changes trigger knock-on changes throughout the codebase, changing the types of lots of things as follows. - nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom> - nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>> - Count() --> Length() - ObjectAt() --> ElementAt() - AppendObject() --> AppendElement() - RemoveObjectAt() --> RemoveElementAt() - ns*Hashtable<nsISupportsHashKey, ...> --> ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...> - nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom> - This requires adding a Get() method to nsRefPtrHashtable that it lacks but nsInterfaceHashtable has. - nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>> - nsArrayBase::Create() --> nsTArray() - GetLength() --> Length() - do_QueryElementAt() --> operator[] The patch also has some changes to Rust code that manipulates nsIAtom.

# Read the user's .mozconfig script.  We can't do this in
# autoconf puts the argument parsing code above anything
# expanded from, and we need to get the configure options
# from .mozconfig in place before that argument parsing code.
