nsRange::DoSetRange() adds/remove its root to/from mutation observer, initializes common ancestor, registers itself to the common ancestor, unregisters itself from old common ancestor, and notifies selection listeners of selection change.
However, those runtime cost is expensive but on the other hand, a lot of callers set both start and end of the range and that causes calling DoSetRange() twice.
This patch renames Set() to SetStartAndEnd() for easier to understand the meaning and make it call DoSetRange() only once.

In the next patch we want to add a method called
GetUnanimatedStyleContextForElementNoFlush but that's much too long. Instead it
seems better to just drop 'ForElement' from all these methods since it should be
fairly obvious we are getting the style context for an element given that the
first argument is an element.

When nsRange::*JS() is called, mCalledByJS is set to true. In such case, Selection::NotifySelectionListeners() may move focus or anyway, it calls selection listeners. Then, they may cause calling non-*JS() methods of the nsRange instance. In this case, nsRange treats the call as called by JS since mCalledByJS is still true.
For preventing this issue, before calling Selection::NotifySelectionListeners(), nsRange should set mCalledByJS to false.
This patch renames AutoCalledByJSSetter to AutoCalledByJSRestore and make it stop setting mCalledByJS automatically. So, AutoCalledByJSRestore works same as AutoRestore now.

Selection may be changed by methods of Selection or methods of Range retrieved by Selection.getRangeAt(). Selection::NotifySelectionListeners() is called after every selection change of each of them, so, this method must be a good point to move focus.
If new common ancestor of all ranges is editable and in an editing host, we should move focus to it. Otherwise, if an editing host has focus but new common ancestor is not editable, we should move focus from the editing host.
For consistency with the other browsers, this patch doesn't move focus to other focusable element.

Selection needs to be able to distinguish if every selection change is caused by JS (i.e., via Selection API) or the others.
This patch maps some methods of Range and Selection to *JS(). Each of them marks its instance as "used by JS" and calls corresponding method.
With this change, Selection::NotifySelectionListeners() can move focus only when it's caused by Selection API.

The main renaming was generated with the following python script:
```

CAMEL_CASE_REGEX = re.compile(r"(^|_|-)([A-Z])([A-Z]+)")
DISPLAY_REGEX = re.compile(r"\bNS_STYLE_DISPLAY_([^M][A-Z_]+)\b")

for line in f:
lines.append(process_line(line))

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
