pci_bus: Fix endianness of split-to-bytes accesses
...
The write side is properly split in little-endian, but for some
reason the read side is reconstructing the word/double-words in
big-endian format.
This never showed up before because ATM _all_ access are byte
access anyway because the handler isn't declared as word/dword
capable.

Fix timer handling to make IRQ 0 an edge trigger interrupt. Add code to PIC emulation to process said interrupts as edge trigger, do not signal the IRQ unless PIC_DeActivateIRQ() is called, then PIC_ActivateIRQ(). For some reason, this also seems to fix the audio in Tyrian 2000, though the audio still sounds a tiny bit crackly

DMA: Help other emulation code by offering a way to determine what triggered DMA_MASKED and DMA_UNMASKED events. It is not always the DOS guest that does it, internal functions of the DMA controller can cause it too

DMA: Add callback event for when the guest reads DMA channel status. Sound Blaster: If the guest reads DMA status, render up to current time so that the guest can see very accurate DMA counter movement. This still does not fix the occasional pop/crackle in Windows 95 if the sound driver is interrupted, but it seems to help Tyrian 2000 and remove the need for using Goldplay mode though audio still sounds a little bit crackly.
