Revise the SystemState hierarchy.
* Removed all #includes from SystemState; added includes in .cc files
that use the various objects (MetricsLibrary, DevicePolicy, etc).
* MockSystemState:
- Regulated the set of getters/setters: foo() returns the current Foo
object interface; this object can be overridden by set_foo();
mock_foo() or fake_foo() returns the default (internal) mock/fake
equivalent, and fails if it is different from foo() (safety).
- Make member declaration order consistent with that of API.
- Removed MOCK_METHOD declarations for two methods and replaced them
with fake getter/setter. This means that MockSystemState is now
reduced to a fake, and can be renamed (separate CL). This also means
that a few tests have a slightly different semantics now.
* All virtual overrides are qualified as such. However, removed the
'const' method qualified from all getters: it made little sense,
especially when considering that getters are handing addresses of
internal mock members.
* Made the UpdateAttempter a contained member of both
{Real,Mock}SystemState, resolving initialization dependencies. In
general, the invariant is that all members of the SystemState that
rely on it being fully populated by the time of their initialization,
need to export a separate Init() method, that will be called (by the
SystemState implementation constructor or Init() method) only after
all members are set.
* Made the mock GPIO handler and connection manager contained members of
MockSystemState; the destructor could safely be moved.
* Cleanup in UpdateAttempter (part of resolving dependencies):
- Ordinary member initialization done via default initializers
(constants) or initializer list in the constructor (parameters).
- Init() method only does work that cannot be done during
construction, with appropriate comment documenting the need for it.
- Better reuse via constructor delegation.
