- Consolidate init-related headers (just init.h and initializer.h)
- Factor out a separate DependencyGraph component
- Remove MONGO_DEFAULT_PREREQUISITES, MONGO_NO_PREREQUISITES, MONGO_NO_DEPENDENTS.
- Document the role of the "default" initializer.

every unit test.
This patch does several loosely related and surprisingly hard to separate things.
1.) Make the ServiceContext class final
2.) Create a mechanism, called ConstructorActions, for running methods on
ServiceContexts immediately after they're built and immediately before they're
destroyed.
3.) Introduce / improve test fixture base classes for tests, giving them fresh
ServiceContext instances for each test case. There is one fixture for tests that
need a storage engine and another for those that do not.
4.) Make several remaining global variables SC decorations in support of (3)
5.) Replace many MONGO_INITIALIZERS that access getGlobalServiceContext with the
new constructor-actions system, which is needed for (3.)
6.) Fix up tests to use the fixtures from (3) and fix tests that silently used
different service contexts in together in a technically illegal fashion that now
breaks.
7.) Utilize (2) as necessary to simplify initialization of new ServiceContexts,
simplifying the fixtures in (3).

- ServiceContext* is now closer to be an instance context for the database. We still don't support multiple instances but I wrote the new code with this in mind. Teardown and reinitialize then becomes a matter of being able to delete and re-create the ServiceContext*.
- Use the new MONGO_INITIALIZER that supports deinit/reinit to be able to re-initialize global systems that are decorations on ServiceContext.
- Move creation/destruction of ServiceContext* out of MONGO_INITIALIZER. This so we can hold an exclusive lock during as much as possible of the shutdown (like how mongod does)
- New ServiceContext registrer where we can link in different implementations of ServiceContext (replaces the SetGlobalEnvironment MONGO_INITIALIZER)
- As a result the SetGlobalEnvironment prerequisite for MONGO_INITIALIZERs is gone.
- The ServiceContext is passed to runGlobalInitializers, put in InitializationContext/DeinitializationContext so the initializers know which context they operate on.
