(I think!) make the AR8327 switch correctly handle traffic.
This patch does four things:
* it globally disables mirroring;
* it globally sets the mirroring on each port to be disabled;
* the initial port setup now programs a portmask for the port to allow
transmission (forwarding) to all other ports bar itself;
* the vlan setup path now programs the portmask for the port to
allow transmission (forwarding) to all other ports bar itself.
Before this, I hard-coded the portmask to 0x3f which would mean all
ports (bar port 6, which currently isn't hooked up to anything.)
This means that traffic would be duplicated back out the port it
received it. I bet this wasn't .. optimal.
In any case, this _seems_ to make DHCP from my macosx laptop
work through this access point. I'll do some further testing
to ensure it's actually working correctly on all my devices.

Fix a race between VMRUN() and vcpu_notify_event() due to 'vcpu->hostcpu'

potentially result in a missed notification about a pending interrupt to

VM exit.
The vcpu's hostcpu is now updated concurrently with the vcpu state change.
When the vcpu transitions to the RUNNING state the hostcpu is set to 'curcpu'.
It is set to 'NOCPU' in all other cases.
To help avoid confusion: when attempting to send a key file check to see if a
file of the same name exists with a '.pub' suffix and send that instead. This
mimics the behavior of other ssh-copy-id scripts.

Add the bluetooth information structs to the firmware RX statistics message.
It turns out that there's a variant format of the RX statisitcs notification
from the intel firmware. It's even more whacked - the non-BT variant has
bluetooth fields; apparently some later NICs return even _more_ bluetooth
related fields.
I'll commit the statistics structure changes here - it's a no-op for the
driver. I'll later teach the driver code to populate a statistics structure
from the received message after reformatting things correctly.
I don't _think_ it's going to fix anything related to sensitivity programming
as the CCK/OFDM (non-11n) fields are in the same place for both formats.
But the HT structure and the general statistics aren't in the same place.
I'll go find some NIC(s) that spit out the other format and when I find one,
I'll go and update the driver to handle things correctly.
Tested:
* Intel 5100 (which returns the legacy, non-BT format)

Fix a crash that occurs when PWD is invalid.
MCJIT needs to be able to run in hostile environments, even when PWD
is invalid. There's no need to crash MCJIT in this case.
The obvious fix is to simply leave MCContext's CompilationDir empty
when PWD can't be determined. This way, MCJIT clients,
and other clients that link with LLVM don't need a valid working directory.
If we do want to guarantee valid CompilationDir, that should be done
only for clients of getCompilationDir(). This is as simple as checking
for an empty string.
The only current use of getCompilationDir is EmitGenDwarfInfo, which
won't conceivably run with an invalid working dir. However, in the
purely hypothetically and untestable case that this happens, the
AT_comp_dir will be omitted from the compilation_unit DIE.
This should help fix assertions occurring with ports-mgmt/tinderbox,
when it is using jails, and sometimes invalidates clang's current
