Applied the recent mainline PCem commits (and fixed the Pentium machines);

Ported the Roland MT-32 emulation (using MUNT) from bit's MT32 emulation branch of PCem;
Sanitized the OpenAL give buffer code in openal.c a bit;
NVR path is now specifiable in the Settings dialog;
Added Logitech 3-button serial mouse per protocol description by waltje;
The RTL8029AS and the BT-958D now actually use the PCI IRQ routing;
Fixed BT-958D PCI device initialization on the bus;
PCI IRQ routing now respects the edge/level setting set on ports 4D0/4D1.
