Finish my Interruption revamp. - Move interrupt-related code from bop.c to int32.c - Introduce InitializeInt32 helper so that one can initialize all the needed 16-bit stubs for the 32-bit interrupts. - Remove unneeded defines in emulator.h and an exported variable in ntvdm.h. svn path=/branches/ntvdm/; revision=60908
