Merge vendor bugfix for a possible deadlock related to async destroy
and improve write performance by introducing a new lock protecting
tx_open_txg.
Illumos ZFS issues:
3642 dsl_scan_active() should not issue I/O to determine if async
destroying is active
3643 txg_delay should not hold the tc_lock

route. What it was is there are two places in ip_output.c
where we do a goto again. One place was fine, it
copies out the new address and then resets dst = ro->rt_dst;
But the other place does *not* do that, which means earlier
when we found the gateway, we have dst pointing there
aka dst = ro->rt_gateway is done.. then we do a
goto again.. bam now we clobber the default route.
The fix is just to move the again so we are always
doing dst = &ro->rt_dst; in the again loop.

GDT from the correct segment, otherwise a triple fault would be caused.
In some virtual environments (VMware, VirtualBox, etc) this could lead
to a unhandled error or hang in the guest emulation software.
Thanks to avg and jhb for a few hints in the right direction.

instead of kernel_map size to prevent kernel memory exhaustion
by mbufs and a subsequent panic on physical page allocation
failure.
On architectures without a direct map all mbuf memory (except
for jumbo mbufs larger than PAGE_SIZE) comes from kmem_map.
It is the limiting factor hence.
For architectures with a direct map using the size of kmem_map
is a good proxy of available kernel memory as well. If it is
much smaller the mbuf limit may be sub-optimal but remains
reasonable, while avoiding panics under exhaustion.
The overall mbuf memory limit calculation may be reconsidered
again later, however due to the many different mbuf sizes and
different backing KVM maps it is a tricky subject.

Partially implement generic_bs_*_8() for MIPS platforms.
This is known to work with TARGET_ARCH=mips64 with FreeBSD/BERI.
Assuming that other definitions in cpufunc.h are correct it will
work on non-o64 ABI systems except sibyte. On sibyte and o32 systems
generic_bs_*_8() will remain panic() implementations.

a non-ISA IRQ can't fit into a plain IRQ resource. If we encounter a
link like this, build the resource buffer from _PRS instead of _CRS.

than VLAN groups.
Some chips (eg this rtl8366rb) has a VLAN group per port - you first
define a set of VLANs in a vlan group, then you assign a VLAN group
to a port.
Other chips (eg the AR8xxx switch chips) have a VLAN ID array per
port - there's no group per se, just a list of vlans that can be
configured.
So for now, the switch API will use the latter and rely on drivers
doing the heavy lifting if one wishes to use the VLAN group method.
Maybe later on both can be supported.

I'll chase down the root cause of that soon; this at least works around
the bug and tells me when it happens.
This allows users who boot without loader to adjust their environments
around slightly buggy or slow hardware.
