Log:
- Create \dev\physmem section during section initialization, not later.
- Setup SharedUserData settings during Phase 0, not Phase 1. Fixes an old bug where the
Inbv driver assumed ReactOS was in "server mode" simply because the default
SharedUserData->NtProductType was "0" (which is an invalid product type, but
it's != NtProductTypeNt).
  - Also fixed it such that this reports NtProductServer, which is what ReactOS reports to
be (Windows 2003 Server SP 1).
- Initialize the modified page writer and balancer thread in phase 1, not phase 2.
  - Phase 2 should make the executive pageable, but I don't think this is supported
yet...
