a768d54939 - the system of using the bx_param_c::set_handler() callback functions
to change the enable/disable status of other parameters worked fine for
  the text mode interface but poorly for the wxWindows gui.  So I
  implemented it a different way.  Now in every boolean parameter, there is
  a field called dependent_list which is a list of parameters which
  are enabled/disabled by that boolean.  Having this list available
  allows both the text mode CI and the wxWindows CI to know which fields
  should be enabled and disabled as a result of a boolean changing value.
- when the set() method of a bool param is called, or when the
  dependent_list is changed, a private method called update_dependents()
  changes the enabled status of all dependent parameters.
- add macros to get parameter ids of serial and parallel port parameters,
  using the port number as an input variable.

- I've made this change in many of the parameters, in the init code of
  main.cc.  When I add a dependent_list, I no longer need the "handler"
  so I remove the call to set_handler and the cases in the handler
  functions.
- in the process, I also made the serial and parallel port init code
  into loops, instead of hardcoded initialization.  Now if you change
  the number of serial/parallel ports in bochs.h the correct number of
  ports will be initialized and the menus will grow/shrink accordingly.
- fixed up a few names to improve the look of ParamDialog generated
  dialogs.

a43c1391d3 - add DEFAULT_LOG_ACTIONS(level) macro to supply defaults
- define preproc macros for BX_N_SERIAL_PORTS and BX_N_PARALLEL_PORTS
  so that if you want to change the number, you only have to change it
  in one place.

eaa2f87f05 - logfunctions constructor tries to read bx_options.log.actions[]
to get default values, but I didn't initialize bx_options until
  bx_init_options().  I still think that removing the initializer
  was the right choice, so I made a macro in bochs.h called
  DEFAULT_LOG_ACTIONS(level) that supplies the defaults instead.

55498cf4a3 - init bx_options using a few simple lines of code, instead of a monstrous
initializer full of NULLs and zeroes that has to be fixed every time
  we change the bx_options_t type.

b74269a3b7 - add generic dialog class called ParamDialog. You create it, call
a method to add the parameters (bx_param_c) that you want to edit,
  and display it.  It knows how to display and edit boolean, int,
  enum, and string, so it can do a reasonable job on any parameter.
  The end result is not as nice as a box that you lay out by hand, but
  it's decent.  The most obvious thing that's missing from
  ParamDialog-generated dialogs is that I haven't found a way to
  make an "Enable" button that enables/disables a bunch of other
  parameters.  I'll keep thinking about that.
- using ParamDialog, I made dialogs for Sound, Cmos, Serial/Parallel,
  32bitOSloader, and an ugly catch-all category called other.
  Now I believe you can edit every single option using wxWindows.

3f2d28f86c Added guest2host TLB tricks to read-modify-write variants of
access routines in access.cc, completing the upgrade of
those routines.  You do need '--enable-guest2host-tlb', before
you get the speedups for now.  The guest2host mods seem pretty
solid, though I do need to see what effects the A20 line has
on this cache and the paging TLB in general.

b9439c5f61 - correct abuse of local variable in bx_param_bool_c::text_ask. I had created
a temporary char[] buffer, filled it using sprintf, and then used a pointer
  to it even after it went out of scope.

1267d19090 - add ConfigKeyboardDialog
- remove the format string from GetTextCtrlInt() because the strtoul
  conversion is better than the sscanf with a format string (it supports
  both base 10 and 16 with 0xFF notation).

367c549fc4 - fix those browse buttons on the MemoryConfigDialog
- also other browse buttons were somewhat broken in that they didn't
  set the initial value of the wxFileDialog.  Now all text fields
  with a browse button use a single function BrowseTextCtrl() to
  avoid future problems of this sort.
- if the Ok on the MemoryConfigDialog is rejected because the integers
  can't be parsed, now give a more specific error message that points you
  to which field has the illegal value.
- print hex numbers with CAPS.  With proportional font this is much
  easier to read.
- accept either strings with base 10 or 16 numbers in GetTextCtrlInt by
  default.  If the sscanf fails, accept anything that strtoul can
  read.  Unfortunately legitimate "-1"'s being returned from strtoul will
  be rejected, but at present there is no need for negative numbers in
  textfields anywhere.

746f09b427 There's a bug in the repeated IO & mem copy speedups. I
added --enable-repeat-speedups with default to disabled.
Reconfigure/recompile and the speedup code will be #ifdef'd
out for now.  It manifested as junk written to the VGA screen
while booting/running Windows.

Also made some more mods to the main cpu loop.  Moved the
handling of EXT/errorno outside the main loop, much like
the extra EIP/ESP commits were moved, for a little better
performance.

I changed the fetch_ptr/bytesleft method of fetching to
a slightly different model, which calculates a window
for which EIP will be valid (land on the current page),
and a bias which when applied to EIP will be from
0..upper_page_limit.  Speed is about the same for either
method, but a pseudo-op/threaded-interpreter will plug
in better with this and be faster.

0268014110 - add LogOptionsDialog that lets you decide whether to ignore, report,
die, or ask the user for each type of event.  It has a button that
  will lead to the "advanced" dialog, which doesn't exist yet.
- in gui/wxdialog.h, sketch a few more dialogs to be done soon

1cda50d9f2 - make all packet mover classes report their log messages using the NE2K
class's prefix, NE2K.  The real issue is that the ne2k class exists at
  configuration time, so it is possible to tell it how to respond to
  panics, errors, etc.  The packet mover is created after configuration
  depending on the setting of bx_options.ne2k.Oethmod, so I cannot
  (with major hacks) affect its settings from the configuration interface.
  Several packet movers were already set up this way anyway.

3a5f338419 Integrated patches for:
- Paging code rehash.  You must now use --enable-4meg-pages to
    use 4Meg pages, with the default of disabled, since we don't well
    support 4Meg pages yet.  Paging table walks model a real CPU
    more closely now, and I fixed some bugs in the old logic.
  - Segment check redundancy elimination.  After a segment is loaded,
    reads and writes are marked when a segment type check succeeds, and
    they are skipped thereafter, when possible.
  - Repeated IO and memory string copy acceleration.  Only some variants
    of instructions are available on all platforms, word and dword
    variants only on x86 for the moment due to alignment and endian issues.
    This is compiled in currently with no option - I should add a configure
    option.
  - Added a guest linear address to host TLB.  Actually, I just stick
    the host address (mem.vector[addr] address) in the upper 29 bits
    of the field 'combined_access' since they are unused.  Convenient
    for now.  I'm only storing page frame addresses.  This was the
    simplest for of such a TLB.  We can likely enhance this.  Also,
    I only accelerated the normal read/write routines in access.cc.
    Could also modify the read-modify-write versions too.  You must
    use --enable-guest2host-tlb, to try this out.  Currently speeds
    up Win95 boot time by about 3.5% for me.  More ground to cover...
  - Minor mods to CPUI/MOV_CdRd for CMOV.
  - Integrated enhancements from Volker to getHostMemAddr() for PCI
    being enabled.

9e67dcb3e1 - add NetConfigDialog box, that configures networking settings
- for all modal dialogs that return a boolean result, return either
  wxOK or wxCANCEL instead of 0,-1.
- you can view the NetConfigDialog box if you choose the Edit:Network menu
  item, but it's not connected to the actual parameter values yet.

ffc84c8be9 - add BX_SCHEDULED_DIE_TIME which causes Bochs to exit automatically after a
certain number of instructions.  I use it for performance testing, and it
  won't hurt anyone unless they are foolish enough to enable it in config.h.
  Of course it is disabled by default!

572fc4ed57 - I had been misunderstanding how you're supposed to convert wxStrings
into normal C strings.  After asking about it on wx-users, I understand
  it better now.

  Example of unsafe code:
    char *filename = dlg.GetFilename().c_str ();
    printf ("file name is %s\n", filename);

  The problem is that dlg.GetFilename() returns a temporary wxString
  that goes out of scope at the end of that line of code.  The "filename"
  string is unstable if you write it this way.

  Example of safe code:
    char filename[1024];
    wxString fn (dlg.GetFilename ());
    strncpy (filename, fn.c_str (), sizeof(filename));
    printf ("file name is %s\n", name);

  Now we have a stable copy of the wxString in "fn" which is usable
  as long as fn is in scope.

- also now we use wxStrings (almost) all the time in the interface to the
  wxdialogs.  Any conversion from char* to wxString and back is done in
  wxmain.cc now.

d52b23daf1 Made some very minor mods, to make CPUID aware of CMOV instructions
for BX_CPU_LEVEL >= 6, and to have the CMOV instructions generate
an undefined opcode exception after printing info that they were
called, if BX_CPU_LEVEL <= 5.  I suppose we could have a separate
configure option, but mirroring Intel, CMOV is available as of
Pentium Pro.

For now, you have to compile with --enable-cpu-level=6 for CMOV
support to be compiled in.
