cxgbe/iw_cxgbe: fix various double-close panics with iWARP sockets.
Sockets representing the TCP endpoints for iWARP connections are
allocated by the ibcore module. Before this revision they were closed
either by the ibcore module or the iw_cxgbe hardware driver depending on
the state transitions during connection teardown. This is error prone
and there were cases where both iw_cxgbe and ibcore closed the socket
leading to double-free panics. The fix is to let ibcore close the
sockets it creates and never do it in the driver.
- Use sodisconnect instead of soclose (preceded by solinger = 0) in the
driver to tear down an RDMA connection abruptly. This does what's
intended without releasing the socket's fd reference.
- Close the socket in ibcore when the iWARP iw_cm_id is destroyed. This
works for all kinds of sockets: clients that initiate connections,
listeners, and sockets accepted off of listeners.

Local APIC: add support for extended LVT entries found in AMD processors
The extended LVT entries can be used to configure interrupt delivery
for various events that are internal to a processor and can use this
feature.
All current processors that support the feature have four of such entries.
The entries are all masked upon the processor reset, but it's possible
that firmware may use some of them.
BIOS and Kernel Developer's Guides for some processor models do not assign
any particular names to the extended LVTs, while other BKDGs provide names
and suggested usage for them.
However, there is no fixed mapping between the LVTs and the processor
events in any processor model that supports the feature. Any entry can be
assigned to any event. The assignment is done by programming an offset
of an entry into configuration bits corresponding to an event.
This change does not expose the flexibility that the feature offers.
The change adds just a single method to configure a hardcoded extended LVT
entry to deliver APIC_CMC_INT. The method is designed to be used with
Machine Check Error Thresholding mechanism on supported processor models.
For references please see BKDGs for families 10h - 16h and specifically
descriptions of APIC30, APIC400, APIC[530:500] registers.
For a description of the Error Thresholding mechanism see, for example,
BKDG for family 10h, section 2.12.1.6.

Implement sbuf_prf(), which takes an sbuf and outputs it
to stdout in the non-kernel case and to the console+log
in the kernel case. For the kernel case it hooks the
putbuf() machinery underneath printf(9) so that the buffer
is written completely atomically and without a copy into
another temporary buffer. This is useful for fixing
compound console/log messages that become broken and
interleaved when multiple threads are competing for the
console.

Use "build" instead of "all" when building ports modules
"all" in ports currently means "stage the ports", which requires root today,

Make kernel breakpoints work for book-e
Add the necessary bits to enable kernel breakpoints for Book-E. The entrypoint

AIM, add it into the standard trap handler.
This wasn't blocked out as Book-E specific because it is only a minor redundancy
over AIM, which should have already called db_trap_glue() at this point. If
it's going to panic with a fatal trap anywya, it doesn't matter if it goes
