the linker set of CPU modules. The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful. delay and cpu_reset now work much earlier in the
boot process.
Renamed the kern.cam.ada.ada_send_ordered sysctl and tunable to
kern.cam.ada.send_ordered, more in line with the other da sysctls/tunables.

bin/sh has been taught about el_gets setting the count to -1
on error, so now we can partially revert r238173 to reduce
differences with NetBSD's implementation.
Unfortunately NetBSD's libedit handling of EINTR (Revision
1.44 in read.c + SIGWINCH fixes) still causes trouble in
bin/sh and other utilities and has to be avoided.

On recent versions of NetBSD's libedit, el_gets
now sets el_len to -1 on error so we can
distinguish between a NULL string and an error.
This fixes sh from exiting with newer versions
of libedit now allowing EINTR to return.

o Create a linker_set for the support fucntions for the SoCs.
o Rename soc_data to soc_info.
o Move the delay and reset function pointers to new soc_data struct
o Create elements for all known SoCs
o Add lookup of the SoC we found, and print a warning if it isn't one
we know about.

These probes are most useful when looking into the structures
they provide, which are listed in io.d. For example:
dtrace -n 'io:genunix::start { printf("%d\n", args[0]->bio_bcount); }'
Note that the I/O systems in FreeBSD and Solaris/Illumos are sufficiently
different that there is not a 1:1 mapping from scripts that work
with one to the other.

PCI:
- Properly handle interrupt fallback from MSIX to MSI to legacy.
The host may not have sufficient resources to support MSIX,
so we must be able to fallback to legacy interrupts.
- Add interface to get the (sub) vendor and device IDs.
- Rename flags to VTPCI_FLAG_* like other VirtIO drivers.
Block:
- No longer allocate vtblk_requests from separate UMA zone.
malloc(9) from M_DEVBUF is sufficient. Assert segment counts
at allocation.
- More verbose error and debug messages.
Network:
- Remove stray write once variable.
Virtqueue:
- Shuffle code around in preparation of converting the mb()s to
the appropriate atomic(9) operations.
- Only walk the descriptor chain when freeing if INVARIANTS is
defined since the result is only KASSERT()ed.

If an error occurs when transmitting one mbuf in a chain of fragments,
free the subsequent fragments instead of leaking them.

the FIFO.
I still see some corner cases where no RX occurs when it should be
occuring. It's quite possible that there's a subtle race condition
somewhere; or maybe I'm not programming the RX queues right.
There's also no locking here yet, so any reset/configuration path
state change (ie, enabling/disabling receive from the ioctl, net80211
taskqueue, etc) could quite possibly confuse things.
