b193480908 Add extensible malloc types, adapted from FreeBSD. This turns 
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

1339e88a86 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).

46b2a2fcd4 Do ess_config_addr() in the ofisa front end, rather than in the match 
routine. Prevents problems with non-SCR ess chips, as described in
PR 11630.

889c658b5b 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.

fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns 
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.

70e38aa504 Fix bug uncovered by audio.c fix: Since the monitor control on the ESS 
is a muting control, not a level control, change the name to reflect that.

XXX The fact that the audio code depends on the string names of the
XXX mixer devices is bogus.

81a1ade358 More redux: 
* Use a single routine to halt both input and output on Audio1.
* Reduce the number of register reads/writes used to set up a channel.

3e404912dc Clean up the previous: 
* Separate the interrupt handlers based on which channel (audio1/audio2)
  rather than which direction (input/output).  Only register the handler for
  audio1 on the 1788.
* Since the input sides are actually the same, GC the duplicated code.
* Re-KNF in a bunch of places.
* Make this work again on the 1887 in the Shark.

cd09067eb4 * Redo the way the way the MIDI driver attaches to audio devices. 
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
  The opl driver is not finished yet; it sounds pretty awful.

For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
