Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite;
Added device.c/h API to obtain name from the device_t struct;
Significant changes to win/win_settings.c to clean up the code a bit and fix bugs;
Ported all the CPU and AudioPCI commits from PCem;
Added an API call to allow ACPI soft power off to gracefully stop the emulator;
Removed the Siemens PCD-2L from the Dev branch because it now works;
Removed the Socket 5 HP Vectra from the Dev branch because it now works;
Fixed the Compaq Presario and the Micronics Spitfire;
Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470;
SMM fixes;
Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions;
Changed IDE reset period to match the specification, fixes #929;
The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset;
Added the Intel AN430TX but Dev branched because it does not work;
The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full);
Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types;
USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it);
Fixed NVR on the the SMC FDC37C932QF and APM variants;
A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX;
Some ACPI changes.
