actually change the CD. The extra insert/eject cycles were coming from the

changed wxdialog.cc and textconfig.cc to only call set() on parameters if
they are different from the original value. Now it generally does what you
would expect.

This fixes bug #614724: SDL can get stuck in full-screen mode, and provides
a framework for fixing the problem on other full-screen display libraries
such as term, svga, etc.
- add virtual method bx_gui::set_display_mode(mode) which can be overridden
by each display library class, if appropriate. This method is primarily
used when you run Bochs full screen, to tell the gui to switch from full
screen back to a mode where you can use the text console.
- There are two display modes: config and simulation. The mode is changed to
config mode during logfunctions::ask, during the runtime configuration menu,
and before displaying a debugger prompt. It is changed back to simulation
mode whenever instructions are running.
- Instead of being called directly through the global bx_gui pointer, the
bx_gui_c::set_display_mode() method is almost always accessed through
siminterface, like this:
SIM->set_display_mode (DISP_MODE_CONFIG);
SIM->set_display_mode (DISP_MODE_SIM);
Of course siminterface just passes the call on to bx_gui::set_display_mode().
I added it to siminterface so that the config interfaces could call it.
(They don't #include bochs.h so they can't access bx_gui.)

This untested patch shows how and where to call RedirectIOToConsole() when

fix the problem of having no console window on SDL.
- enable RedirectIOToConsole() when compiling with SDL on win32, so that
it can be called in main().
- move main() down below the definition of RedirectIOToConsole(), and
add a call to RedirectIOToConsole()
- in WinMain, Bochs always asked the user to press ENTER before exiting.
I moved that code to main() with #ifdef WIN32...#endif around it.
(Maybe this should only be done when Bochs explictly creates a console
window, though.)

Step 1, the compile, must be done locally on a MacOSX machine. This
gives us the contents of the resource fork, which will be checked into
CVS as script_compiled.rsrc every time the script sources change. Step 2
can be done remotely on the SF compile farm: reconstruct the script
from the separate data and resource fork files.
- not all filesystems support resource forks! I added a test in the
makefile to check that the resource fork is accessible, so that at least
we will get a clear error message if the filesystem doesn't support it.
In bx_cpu_c::reset method I set bx_cpu->async_event to 2
so execution in the cpu_loop gets stopped early.
Previously, async_event was set to 0, and with repeatable
instructions, after reset, eip was incremented by the instruction
length, so execution would resume at 0xffffX (X being >0, the current
instruction length).
In halt state I check now for reset with async_event is 2, so
reset works also when the cpu is halted. (update to Peter change)
I hope I fixed this the right way, please report any strange behaviour.

For any software interrupt, hardware interrupt, or exception, Bochs
calls the instrumentation macro BX_INSTR_INTERRUPT(). For each call
to BX_INSTR_INTERRUPT(), this patch adds instrumentation code that
looks up each interrupt in the Ralf Brown x86 interrupt list and
prints the name of the interrupt in English. This output can be very
useful in telling what a user space program is doing.

Now I hope I have it right. After the sed script it should look like
%attr(-,root,root) %dir /usr/lib/bochs
I was having trouble getting the initial / on "/usr/lib/bochs"
files specified as before. This solves the problem of
"error: cannot remove /usr/share/doc - directory not empty"
which I was getting when I tried to remove the RPM.
- moved ne2k presence check to devices.cc
- added special make rules for the ne2k and the lowlevel network support
- added macro for the debug feature of the ne2k
- leave just the two configurations that I plan to build binary RPMs with:
one is conservative with just X11 and the options we used before,
and the other includes plugins, lots of display libraries, etc.
- My previous rev to dbg_main.cc caused the debugger to fail when readline
was disabled. With these changes I have tested more thoroughly and it works
with readline enabled or disabled, and with wxWindows enabled and disabled.
- The Bochs debugger uses BX_WITH_WX to decide to change to wxWindows debugger
behavior: sending a synchronous message to the config interface to get a new
command, sending all dbg_printf output to the config interface, deciding
whether to trap control-C, etc. But now that it's possible to compile with
BX_WITH_WX and BX_WITH_other_things, this isn't quite right anymore. With
this change, we now use calls to a new method SIM->is_wx_selected() to decide
which behavior to use. This method is equivalent to checking if the display
library variable is set to "wx", but it's implemented in such a way that it
only has to check a boolean for each call to SIM->is_wx_selected().
- in siminterface.cc, init some local variables to 0 to avoid compile
warnings.
