This is necessary because HtmlElement.children= requires its parameter
type to be a List<Element>, and text nodes are not elements.

The method ObservatoryApplication._switchVM calls newVM.onDisconnect
and requires the resulting future to be completed with a String. In
normal operation, this is satisfied and we just need to change a few
static types to enforce it. But when FakeVM was in use, the future
was completed with `this`. Since ObservatoryApplication._switchVM is
the only call site that cares what the future is completed with, it
makes sense to just change all the types to Future<String> and modify
FakeVM accordingly.

Add a clause indicating that FunctionCallTreeNode (in
lib/src/sample_profile/sample_profile.dart) implements
M.FunctionCallTreeNode. This allows the two types for `root`
inherited by FunctionCallTree to be consistent with each other: the
type inherited from CallTree<FunctionCallTreeNode> is
FunctionCallTreeNode whereas the type inherited from
M.FunctionCallTree is M.FunctionCallTreeNode.

Since the downcast is explicit (using "as") the type will be checked
even in unchecked mode, so technically there is a slight risk of
breakage. But since the callback is so near the creation of the
ButtonElement, I'm not concerned. Also, I'm not concerned about the
performance penalty of the explicit downcast because the cost is only
paid once per user click.

In some cases we need to specify a type because the inferred type
would be too specific. For example, in the code:
final content = [new SampleBufferControlElement(...)];
...
content.addAll([new BRElement(), ...]);
Strong mode would infer a type of `List<SampleBufferControlElement>`
for `content`, making it impossible to add other kinds of HTML
elements to the list later. So we have to specify explicitly that the
list element type is meant to be `HTMLElement`.
In other cases we need to specify a type because the inferred type is
too general. For example, in the code:
Future<List<String>> complete(...) {
var result = [];
...add values of type String to `result`...
return new Future.value(result);
}
Strong mode would infer a type of `List<dynamic>` for `result`, making
it impossible to enclose in a `Future<List<String>>`. So we have to
specify explicitly that the list element type is meant to be `String`.

This CL makes the following changes, which should be safe since they
don't affect Dart 1.0 semantics:
- Explicitly declare the types of certain variables as `dynamic` to
avoid strong mode inferring a type that leads to errors.
- Explicitly cast certain expressions to `dynamic` to allow access to
members that are dynamically known to be present.
- Add `covariant` annotation to method parameters that are a subtype
of the corresponding parameter in the base class.

This CL addresses a code pattern where a method expects its parameter
to have a certain type, but that method is torn off and passed as a
callback to another method expecting its parameter type to be more
general. For example:
void f(int i) { ... }
void g(void callback(Object o)) { ... }
void h() {
g(f); // Error: () -> int is not a subtype of () -> Object
}
This is a strong mode error because the type system cannot guarantee
that the value pased to f will be an int. The solution is to broaden
the type of the callback parameter so that it matches the type
expected for the callback. In most cases, we insert an implicit
downcast (by reassigning the parameter to a local variable with the
expected type), which in Dart 2.0 semantics will result in a runtime
check (similar to what happens in Dart 1.0 checked mode).
Since the downcasts are implicit, the Dart 1.0 semantics are
unchanged, so this should be a safe change.

This ensures that the resulting Iterable will have the proper type
when run with strong mode semantics.
In Dart 1.0 semantics, the type argument to .map is ignored, so this
change should be safe.

This is necessary because many call sites invoke toUserString without
first casting to one of the derived classes.
This should be safe since both derived classes (SourceLocation and
UnresolvedSourceLocation) contain a definition of toUserString.

This CL fixes some cases where Observatory mistakenly tried to use a
C-style parameter declaration, e.g.
void foo(String);
The intent is to declare the parameter to have type `String`, but Dart
interprets the parameter as having *name* `String` and type `dynamic`.
In most cases the fix applies to abstract method declarations, whose
types aren't semantically relevant in Dart 1.0, so these parts of the
CL should be safe.
In one case it applies to a typedef, IsConnectedVMTargetDelegate. The
only use of this typedef is as the type of
TargetRepository._isConnectedVMTarget, whose value is always the
static function ObservatoryApplication.isConnectedVMTarget. The type
of ObservatoryApplication.isConnectedVMTarget matches the typedef
(according to Dart 1.0 rules) both before and after the change, so
this should be safe as well.

This CL addresses a code pattern where a method has a more general
return type than it needs, causing a strong mode error at the site
where the method is called or torn off. For example:
Object f() => 'x';
void g(String callback()) { ... }
void h() {
g(f); // Error: () -> Object is not a subtype of () -> String
}
The solution is to tighen up the return type. In all cases in this
CL, it is obvious from the method definition that the value returned
at runtime will satisfy the tighter return type, so this should be a
safe change.
