- special case socket(2) call, it's also the only one with first argument
not being a socket descriptor

of always the whole structure

With no menu items the mbr_bootsel code will wait for the timeout (default
10 seconds) and then boot the default device - usually the active partition.
Forcing the 'active' partition was wrong - jmmv has a system which needs
to boot from hd1 where hd0 has no mbr partition info.
I suspect the problem I though rev 1.7 fixed was actually caused by
disklabel copying sector zero of the disk to sector zero of the partition!
Gains another 9 bytes of free space, mbr_bootsel now has 20 free bytes.

which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

-add convenience macros for config_found() and config_search() to
ease the case where just an interface attribute is specified
- Clean up the namespace of this module and enable the encode/decode
functions and printing functions.
- Move the code that actually generates the UUID out of the system call
routine and into its own function.

grow-down auto extend segment) by allocating segment sized at
current stack size limit, and offsetting requested/returned address
as required
due to how normal virtual memory management work, allocating the
full sized stack memory segment up-front actually requires exactly same
amount of VA space and physical memory as the Linux 'grow' scheme and the
'grow' scheme is quite a lot more difficult to use in applications correctly,
so it's not very apparent why Linux introduced this feature at all

sd3(mpt0:0:1:0): unable to allocate scsipi_xfer
sd3: not queued, error 12
Havard Eidnes's analysis of this problem is that the scsipi_xfer pool is
competing for resources with other pools, including the the inode and vnode
pools which can grow quite large.
*_scsipi_cmd(): don't biodone the buffer if scsipi_make_xs() fails, let the
caller deal with the problem
start function of block devices drivers: dequeue the buffer after the
scsipi_command() call. If scsipi_command() fails with ENOMEM don't dequeue
the buffer, and schedule a callout to call the start function after
some delay.
scsipi_init(): prime the scsipi_xfer_pool with one page. This ensure that
there is always some scsipi_xfer to play with. If scsipi_command() fails
because of pool_get(), we're sure there will be resources available later,
when the pending commands have completed.
Reviewed by Jason Thorpe and Havard Eidnes.
Todo: remove the "unable to allocate scsipi_xfer" and "not queued, error %d"
printfs, but I choose to keep them for now, to help make sure the code does
what it should.

* Rename PTDpaddr to PDPpaddr, ptdpaddr in struct cpu_kcore_hdr to pdppaddr for consistency.

In DEBUG/DIAGNOSTIC, decrement/increment pmap_pvo_enter_depth around pool
calls since they could possibly cause a recursion back into pmap_pvo_enter.
