Add Atheros AR1111 support to the HAL.

This seems to probe/attach as an AR9485 and thus nothing else besides
adding the device id seems to be required.

ath0: <Atheros AR1111> mem 0xf4800000-0xf487ffff irq 19 at device 0.0 on pci5
ath0: [HT] enabling HT modes
ath0: [HT] enabling short-GI in 20MHz mode
ath0: [HT] 1 stream STBC receive enabled
ath0: [HT] 1 RX streams; 1 TX streams
ath0: AR9485 mac 576.1 RF5110 phy 1926.8
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x0000

The NIC I have here is a 1 antenna, 2GHz only device.

Thankyou to Jim Thompson <jim@netgate.com> for the AR1111 NIC.

Tested:

* AR1111 (pretending not to be an AR9485, but failing miserably);
  STA mode with powersave.

Quieten the RX/TX descriptor and FIFO setup debugging.

Break out the multicast programming into its own hardware specific
call, which assumes the hardware is awake.

Turn ath_update_mcast() into a routine that's only called from the
net80211 layer - and it forces the hardware awake first.

This fixes a LOR from the EDMA RX path which calls ath_mode_init()
with the RX lock held - the driver lock can't also be grabbed.
This path assumes that the ath_mode_init() callers all wake up
the NIC first.

Tested:

* AR9485, STA mode, powersave
Make r242379 - the fix for UFS labels disappearing after resizing
the provider - also apply to UFS1 filesystems.  This should help with
resizing filesystems created by makefs(8), which still uses UFS1.

Improve DWC OTG USB host side support for isochronous FULL and HIGH
speed data traffic going directly to a USB device or through a
so-called USB transaction translator.

Add checks that we are not overusing the TX FIFO.

Virtual machine halt detection is turned on by default. Allow it to be
disabled via the tunable 'hw.vmm.halt_detection'.
Re-adding an event to a kqueue modifies the parameters of the original event.
However, if the original knote had been disabled then it is not automatically
re-enabled.

Fix this by using EV_ADD to create an mevent and EV_ENABLE to enable it.

Adding a kevent for the first time implicitly enables it so existing callers
of mevent_add() don't need to change.

Revert r265367:
Use of calloc instead of malloc in regex (from OpenBSD).

In this case the change makes no sense since we are using realloc() later.

Modify the "-p" option to be more flexible when associating a 'vcpu' with
a 'hostcpu'. The new format of the argument string is "vcpu:hostcpu".

This allows pinning a subset of the vcpus if desired.

It also allows pinning a vcpu to more than a single 'hostcpu'.

Remove the ifconfig test added in rev 263445.  After discussion with
melifaro, we agreed that ifconfig's behavior was not a bug.  The main
motivation for bin/187551 was to partially resolve kern/187549, but we
resolved kern/187549 in a different way instead.

Adjust #if statements inside mprsas_send_smpcmd() to more accurately
reflect when unmapped I/O support was added.

For FreeBSD 10, it arrived just prior to __FreeBSD_version 1000028.
For FreeBSD 9, it arrived just prior to __FreeBSD_version 902001.

Also, fix compiler warnings in mprsas_send_smpcmd() that happen in the
i386 PAE build for non-unmapped I/O builds.  These were fixed in mps(4)
in revision 241145, but didn't make it into the mpr(4) driver.  This
change should only affect FreeBSD versions outside the above revisions,
and thus doesn't affect head.
