Patches applied:
- applied disassembler fixes for by Dirk Thierbach
- applied FPU 64-bit addressing patch
- applied CPU fixes patch by Vitaly Vorobyov
[x] fixed bug in int01 (opcode 0xF1) emulation
[x] fixed bug in x86 debugger with dr0-dr3 registers
[x] fixed bug with mov to/from dr register in v86mode
(now exception is generated (according to Intel documentation)
instead of panic)
[x] fixed stack limit checking, now message is generated as BX_DEBUG,
rather then BX_PANIC, and exception code is executed
