e85a90a720 Remove cpu.h -> devices.cc dependancy, kill_bochs_request moved from CPU to bx_pc_system 
Small Icache simplification and speedup

7b6c2587a9 Now devices could be compiled separatelly from CPU 
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

203a9caf31 SMM mode could leave together with pmode or any other (according to amd docs) 
so we need separate bx_bool indicator in_smm instead

024ce249bf Define SMM mode for future implementation. 
I would like all next commits be aware of SMM mode.
It can't be implemented right now (too many questions w/o answers) but it will be done till next major release definitelly.

37eb82c69c Totally remove the cosimulation code from Bochs. 
The Bochs anyway even doesn't compile if cosimulation configured enabled.
But in the same time the cosimulation code only disturbs to the future development of Bochs debugger, for example adding x86-64 functionality ...
For those of you who still may want to see the cosimulation code inside I put it in patch and upload it Bochs CVS patches folder. Read comments for the patch ! ----------------------------------------------------------------------

18afa9fd2d This is cumulative patch for bochs debugger, it is only very first step towards working debugger supporting all new simulator functionalitieS. 
- move crc.cc from debugger to bochs folder and make it projct-wide and not local for debugger
 - added new 'info sse' command for debugger
 - extend 'modebp' command to break on any mode change
 - remove unimplemened 'info program' function, it is always printed fixed text
 - move debugger help to parser, cleanup and simplify it

08c15c67c0 Don't know how much it helps ... 
First step to make bx debugger supporting x86-64. guard_found object fields conerted to bx_address for x86-64 support.

c92aba3776 Using back tracking in CVS I found the reason why CVS sources not compiled with configure --enable-debugger configuration (reported by Brendan). 
Again it is andom change which cause to debugger not to compile ;(
This is definitelly GCC bug !
