When using -l option targeting file that can't be opened (ie. nmdm module
is not loaded and /dev/nmdm* is specified) bhyve tries to apply capsicum
capabilities to a file that was not opened.
Enclose that code in an if statement and only run it on correctly opened
descriptor also providing meaningful message in case of an error.

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.
