Immediately after clearing a pending callout that didn't make it due
to the lock we hold, disable interrupts, and announce to the firmware
that we are shutting down. Especially do this before disabling blocks.
This makes some types of machines with asf enabled no longer hang upon
boot, when we start configuring the interface.

Turn off use of ATA_A_4BIT on modern hardware. This flag was already
obsoleted in 1996 by ATA-2, and crashes some modern hardware like some
revisions of the Serverworks K2 SATA controller. Even very ancient
hardware seems not to require it. In the unlikely event this causes
problems, the previous behavior can be re-enabled by defining
ATA_LEGACY_SUPPORT at the top of this file.
If socket buffer space appears to be lower then sum of count of
already prepared bytes and next portion of transfer, inner loop of
kern_sendfile() aborts, not preparing next mbuf for socket buffer, and
not modifying any outer loop invariants. The thread loops in the outer
loop forever.
Instead of breaking from inner loop, prepare only bytes that fit into
the socket buffer space.
Fix a functional regression in multicast.
Userland daemons need to see IGMP traffic regardless of the group;

fault panic due to a failed bounce page allocation
during RX mbuf setup. The large demand on bounce pages
is due to the alignment requirement in the tag. This
restriction was removed in the ixgbe driver with no
ill effects and so is being removed here also.

Add a check for the connection being shut down to the krpc
client just before queuing a request for the connection. The
code already had a check for the connection being shut down
while the request was queued, but not one for the shut down
having been initiated by the server before the request was
in the queue. This fixes some cases of problems w.r.t. reconnecting
to a NFS server that drops inactive TCP connections.

- Catch SIGHUP to perform cleanup before exiting.
- Exit if getch() returns with an error other than EINTR. Otherwise
systat(1) may get stuck in an infinite loop if it doesn't receive
SIGHUP when terminal closes.
- Remove attempt to clear stdio error indicators. getch() doesn't use
stdio, making it useless.

Integrate lost interrupts patch from the old USB stack.
Some EHCI chips from VIA / ATI seem to trigger interrupts before writing back
the qTD status, or miss signalling occasionally under heavy load. If the host
machine is too fast, we can miss transaction completion - when we scan the
active list the transaction still seems to be active. This generally exhibits
itself as a umass stall that never recovers.
We work around this behaviour by setting up this callback after any softintr
that completes with transactions still pending, giving us another chance to
check for completion after the writeback has taken place

Initialize the whole message unit's DMA buffer to zero, this fixes a panic

This commit brings the driver to the same state of vendor's 1.20.00.16
release. Many thanks to Areca for their continued support to FreeBSD.

There are known issues with this driver that are beyond what can be
fixed for 8.0-RELEASE and the bugs can cause boot failure on some systems.
It's not clear if it impacts all systems and there is interest in getting
the problem fixed so for now just comment it out instead of remove it.
Commit straight to stable/8, this is an 8.0-RELEASE issue. Head was left
alone so work on it can continue there.
