9c3d374e6a continued work for "wx second run" support 
- memory: initialize ISA and PCI ROM variables in init_memory()
- sb16: remove items from runtime menu in destructor
- gui debugger: show dialog contents (TODO: fix remaining display issues)
- TODO: fix deadlock in bx_wx_gui::handle_events()

cc56245407 started implementing the i430FX chipset 
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets

b560c72b52 - added check for overlapping memory regions using a Bit16u bitmap (each bit 
represents a 64k block in the 1M page)
- fixed some format warnings

de94b08a1a - class bx_list_c now contains a chained list of parameters. Removed the now 
obsolete maxsize parameter from all lists.

ed669adfd1 - rewrite of the PCI memory management code for the expansion ROM and BIOS area 
- store memory type array in the memory object to avoid calling the pci plugin
    frequently. The pci code calls a memory method to change the memory type in
    case the PAM registers are modified.
  - removed now obsolete code and minor cleanups

d11114ac19 Patch for emulating target with larger memory than host has available by Gary Cameron. 
The patch was posted in mailing list at Thu 6/16/2011.

Desription for CHANGES:

- Memory
  - Added new configure option which enables RAM file backing for large guest
    memory with a smaller amount host memory, without causing a panic when
    host memory is exhausted (patch by Gary Cameron). To enable configure with
        --enable-large-ramfile option.

f57b14d338 Extended the interface of the fetch handler to general direct memory access handler. 
Now the handler receives 'rw' (BX_READ, BX_WRTE, BX_EXECUTE) access type as parameter.
If returning a pointer to <addr> - itr is assumed that whole 4K page containing the <addr> could be accessed using the same pointer with offset.
You can return a pointer for READ/WRITE only and disallow execute, this is handled properly in the CPU code.

525e5a46f7 - moved array 'rom_present' to the memory class and initialize it at startup. 
This is required for the "second run" feature of the wx port. The simulation
  thread can be run multiple times without restarting the application.
