C++ makes absolutely no guarantees about the order of initialization of
global variables in different compilation units. The class-scope static
WvCdmTestBase::default_config_ in test_base.cpp invokes the
ConfigTestEnv constructor on creation, which depends on the prior
initialization of several file-scope static variables in
config_test_env.cpp. Since those are different compilation units, there
is no guarantee that they will initialize in the correct order to avoid
referencing uninitialized memory. This is one of the reasons Google
Style really encourages people not to have global-scope variables with
complex types.
As it happens, on all our internal platforms, these files get linked in
such a way that the variables get initialized in the right order and
there is no crash. But that's not guaranteed, and some partners have
reported crashes here. In at least one case, the "right" linker order
was platform-dependent, and the partner ended up having to maintain
separate linker orders for separate platforms.
This patch defers default_config_ initialization until
WvCdmTestBase::Initialize() is called. By that time, all static
variables will be initialized, so it will be safe to reference them.

When we run a test with the fake clock, the clock had been initialized
to the current time, or to 0. This causes a problem for reboot tests
because the clock might go backwards over the reboot. With this
change, we monitor the clock at the end of one reboot pass and
initialize the clock for the next pass based on the previous value.
