Fix sound LOR problems:
dsp_open: rearrange to only hold one lock at a time
dsp_close: ditto
mixer_hwvol_init: delete locking, the only consumer seems to be the ess driver and it only call it a creation time, I think the device will be stable across the sleepable malloc.
cmi interrupt routine: Release locks while caller chn_intr, either this or do what emu10k1 does which is have no locks at in the interrupt handler.

Set a lower bound on fragment size rather than returning a failure when the user specifies a maximum fragment size < 2.
This is the behavior that Linux provides and fixes the problem I've observed in Tribes2 where sounds effects are delayed by 1/2 a second.

- Add vm_paddr_t, a physical address type. This is required for systems where physical addresses larger than virtual addresses, such as i386s with PAE. - Use this to represent physical addresses in the MI vm system and in the i386 pmap code. This also changes the paddr parameter to d_mmap_t. - Fix printf formats to handle physical addresses >4G in the i386 memory detection code, and due to kvtop returning vm_paddr_t instead of u_long.
Note that this is a name change only; vm_paddr_t is still the same as vm_offset_t on all currently supported platforms.

Gigacommit to improve device-driver source compatibility between branches:
Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values.
This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386.

Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour. The device mmap handlers must now give back the physical address without atop()'ing it. - Don't borrow the physical address of the mapping in the returned int. Now we properly pass a vm_offset_t * and expect it to be filled by the mmap handler when the mapping was successful. The mmap handler must now return 0 when successful, any other value is considered as an error. Previously, returning -1 was the only way to fail. This change thus accidentally fixes some devices which were bogusly returning errno constants which would have been considered as addresses by the device pager. - Garbage collect the poorly named pmap_phys_address() now that it's no longer used. - Convert all the d_mmap_t consumers to the new API.
I'm still not sure wheter we need a __FreeBSD_version bump for this, since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

Sound devices were being leaked by dsp_open() not actually releasing the channels it allocates if chn_reset() on them resulted in failure. ARROW'D!
