26056d930c The debugger can call activate_timer() on arbitrary timers, including 
timer 0, so it should not be a fatal error.  Attempting to register,
unregister or deactivate timer 0 is still an error.

8db1de7124 - Fixed several issues, each cause to NullTimer function never be called, the method is required for icache correct functionalit 
- Speed-up icache by correct purging of Icache entries
- Several new assertions for timers, to prevent bugs in future

817b85045e - fixed sharing of growing harddisk images between Windows and Linux caused by 
different data alignment. Added a reserved 32-bit field and changed header
  version to 2.0. The hdimage code can still handle version 1.0 images.

91ada6c72c Separate RepeatSpeedups code in io.cc to stand-alone CPU methods 
FestRepINSW and FastRepOUTSW similar to that is done in string.cc
Done to simplify the code, it was just impossible to understand it.

767fb77ebd Fully handle segment limits inside prefetch method. 
1. Should speed up the simulation (eliminate seg.limit check per every instruction exec)
2. Should help for DT (h.johansson request)

9340f3b3f8 - partial sync with BRANCH_SAVE_RESTORE_3 (hardware save/restore not present yet) 
* changed data format of text files for save/restore (looks like C/C++ structures,
    similar to the format used in old save/restore branches)
  * don't set the initial value of shadow bool parameters
  * don't set the initial value of bool parameters twice
  * cpu/init.cc: missing #undef added
  * ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)
  * floppy.cc: missing initialization of the 'eot' array in reset() added
  * pic.h: type of member 'byte_expected' changed to Bit8u
  * pit_wrap.h: unused members removed
