Added the interface implementation structures.
I remembered from an email that even when asked for a
IDirectInputDeviceA what was returned was an IDirectInputDevice2A so I
considered that we would only implement the latter. The
IDirectInputDeviceA_xxx methods have been renamed to
IDirectInputDevice2A_xxx, and we always return our IDirectInputDevice2A
implementation as before.
Renamed the implementation structures to XxxImpl.

Defined the IDirectInputDeviceA interface independently from
IDirectInputDevice2A.
Removed the 32 suffix of the interfaces. Hopefully this will not
cause any problem with the renaming.
Moved the implementation specific stuff to dinput.c (well, the
interfaces at least).

Removed a few unused fields in PDB and THDB.

Changed initial thread creation to avoid memory allocations.
Moved server startup to THREAD_CreateInitialThread.

- Fix header and source files to include missing header files to avoid
  warnings and errors.
