Add a new optional method, dev_ioctl, to the audio hardware driver interface.
...
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

It seems the fixed rate versions are actually fixed at 48 kHz, not 44.1 kHz.

Change pci_intr_map to get interrupt source information from a "struct
...
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
Tested on alpha and i386; welcome to 1.5Q

Change the kernel mmap interface so that the offset to map is an
...
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
