The TCP server implementation in dbgport does not track clients, so it
may try to write to a disconected socket resulting in SIGPIPE.
Avoid that by setting SO_NOSIGPIPE socket option.
Because dbgport emulates an I/O port to guest, the communication is done
byte by byte. Reduce latency of the TCP/IP transfers by using
TCP_NODELAY option. In my tests that change improves performance of
kgdb commands with lots of output (e.g. info threads) by two orders of
magnitude.
A general note. Since we have a uart emulation in bhyve, that can be
used for the console and gdb access to guests. So, bvmconsole and bvmdebug
could be de-orbited now. But there are many existing deployments that
still dependend on those.

writev() can do a short write. Retrying it results in a very convoluted
and complex code, so we iterate over iovec and do regular stream_write()
instead.

These functions are allowed to overwrite their input. Pull a copy of the
input parameter and call dirname() and basename() on that instead. Do
ensure that we reload the pathname value between calls.
Adds virtio-console device support to bhyve, allowing to create
bidirectional character streams between host and guest.
Syntax:
-s <slotnum>,virtio-console,port1=/path/to/port1.sock,anotherport=...
Maximum of 16 ports per device can be created. Every port is named
and corresponds to an Unix domain socket created by bhyve. bhyve
accepts at most one connection per port at a time.
Limitations:
- due to lack of destructors of in bhyve, sockets on the filesystem
must be cleaned up manually after bhyve exits
- there's no way to use "console port" feature, nor the console port
resize as of now
- emergency write is advertised, but no-op as of now

"io" is the default, and allows VGA i/o registers to be
accessed. This is required by Win7/2k8 graphics guests that
use a combination of BIOS int10 and UEFI.
"off" disables all VGA i/o and mem accesses.
"on" is not yet hooked up, but will enable full VGA rendering.
OpenBSD/UEFI >= 5.9 graphics guests can be booted using "vga=off"
- Allow "rfb" to be used instead of "tcp" for the fbuf VNC
description. "tcp" will be removed at a future point and is
kept as an alias.

There seems no hard limit on number of segments per packet in the chip,
and 20 appeared insufficient. Hope 64 will be enough, but if not -- add
check to report that and drop the packet instead of corrupting stack.
This makes factual interrupt routing match one shipped with UEFI firmware.
With old firmware this make legacy interrupts work reliable for functions 0
of PCI slots 3-6. Updated UEFI image fixes problem completely.
The code was successfully tested with FreeBSD, Linux, Solaris and Windows
guests. This interface is predictably slower (about 2x) then virtio-net,
but it is very helpful for guests not supporting virtio-net by default.
Thanks to Jeremiah Lott and Peter Grehan for doing original heavy lifting.
It was useless before, but may improve performance now if multiple devices
are configured and guest supports this feature.

Add `WRAPPED_CTASSERT` macro by annotating CTASSERTs with __unused
to deal with -Wunused-local-typedefs warnings from gcc 4.8+.
All other compilers (clang, etc) use CTASSERT as-is. A more generic
solution for this issue will be proposed after ^/stable/11 is forked.
Consolidate all CTASSERTs under one block instead of inlining them in
functions.

Original commit message:
Initial bhyve native graphics support.
This adds emulations for a raw framebuffer device, PS2 keyboard/mouse,
XHCI USB controller and a USB tablet.
A simple VNC server is provided for keyboard/mouse input, and graphics
output.
A VGA emulation is included, but is currently disconnected until an
additional bhyve change to block out VGA memory is committed.
Credits:
- raw framebuffer, VNC server, XHCI controller, USB bus/device emulation
and UEFI f/w support by Leon Dang
- VGA, console/g, initial VNC server by tychon@
- PS2 keyboard/mouse jointly done by tychon@ and Leon Dang
- hypervisor framebuffer mem support by neel@
Tested by: Michael Dexter, in a number of revisions of this code.
With the appropriate UEFI image, FreeBSD, Windows and Linux guests can
installed and run in graphics mode using the UEFI/GOP framebuffer.

A couple of minor memory size option related nits:
- use common name 'memsize' (instead of 'max-size' or just 'size')
- bhyve: update usage with memsize unit suffix, drop legacy "MB"
unit
- bhyveload: update usage with memsize unit suffix
- bhyve(8): document default size
- bhyveload(8): use memsize formatting like it's done
in bhyve(8)

Previously, many errors (such as the PCI device not being attached
to the ppt(4) driver) resulted in bhyve silently exiting without
starting the virtual machine. Now any errors encountered when
configuring a virtual slot for a PCI passthru device should be noted
on stderr.
