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 ...

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.

1d4fa8b327 Available back ability to use eip register as source in 'set reg = <expr>' cmd.
Setting the eip register still not available (deliberatelly).
I don't want to enable it util I find some easy interface to do it.
I don't want to allow setting of part of RIP register using 'set eip=<expr>' and leave the upper part unchanged ....

Remove unused test registres from debugger
Fix compilation error in cpu.h

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 ! ----------------------------------------------------------------------

83b4f7ba05 1. remove the ability of using regnames as symbols !
'set $eax = <value>' is stupid when you could do expr like 'set eax = ebx + 4'

2. cleanup and optimize Bochs debugger parsing, fixed several memory leaks

d257f548b9 1. implemented 'set register <name>=<expr>' command, old style 'registers <name>=<exp> command' removed, now 'r|reg|regs|registers' command shows CPU registers contents (same as 'info cpu')
2. new command 'u|disasm|disassemble mode-switch' - switch between Intel and AT&T disasm syntax

3. new command 'u|disasm|disassemble size=n' should be used instead of old 'set $disassembler_size=n'

4. 'h' is a new alias for 'help' command

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

7bf51e48db Print FS_MSR_BASE and GS_MSR_BASE to debug registers dump (requested in bug report [ 1406387 ] JMP instruction should display absolute address)
Fixed fetch mode mask initialization (bug report 1400027  Boundary instruction cache error for uninitialized memory)
For safety only - everytime when changing CS register update fetch mode mask.
Actually it need to be updated everytime when there is a chance for execute mode change or 16/32 bit mode change.
