1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

569aaa3b97 bhyve: avoid applying capsicum capabilities to file that was not opened
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.

9aaefb2c53 bhyve: stability and performance improvement for dbgport
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.

13ee8dde04 Add virtio-console support to bhyve.
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

5a347e3bc3 - Change the fbuf "vga" parameter to "vga=on|io|off".
"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.
