071c5c1a26 A lot of changes but everything is really trivial. 
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead

45f30f0a4c some code written to enter CPU to shutdown state. 
finally the shutdown handling should be done exactly as in VmWare - the GUI should ask user if the CPU should reset and go to HLT/IF=0 if user choosed to stay in shutdown mode.
CPU configure option reset-on-triple-failt should be extended to shutdown-reset=0|1

f8c3968d42 Changes list made after CVS service crash: 
- Fixed critical bug in CPU code added with one of the prev commits
  - Disasm support for SSE4
  - Rename PNI->SSE3 everywhere in the code
  - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
  - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
  - Fixed ENTER and LEAVE instructions in x86-64 mode
  - Added ability to turn ON instruction trace, only GUI support is missed.
    Instruction trace could be enabled if Bochs was compiled with disasm
  - More changes Bit32u -> bx_phy_address
  - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
  - Small code cleanup
  - Update CHANGES and user docs

bbd55fe16f Merge and commit patch.apic-zwane from CVS patches directory. 
the patch release notes by Zwane:

o Define symbols for constants like
o APIC arbitration
o Processor priority
o Various interrupt delivery fixes
o Focus processor checking
o ExtINT delivery

I need to release this now so that i don't fall too far behind CVS, when
it was part of the bochs-smp patch it could boot 2.4.18 4way. Apologies
for the whitespace changes.


Also remove patch.apic-ppr-zwane patch because it already included in
patch.apic-zwane.

I hope it will help to boot x86-64 or cmp systems required missed APIC
features !
