Merge ^/projects/release-arm-redux into ^/head.

Of note:

- This commit adds native FreeBSD/arm release build support without
  requiring out-of-tree utilities.

- Part of this merge removes the WANDBOARD-{SOLO,DUAL,QUAD} kernel
  configuration files, for which the IMX6 kernel configuration file
  should be used instead.

- The resulting images have a 'freebsd' user (password 'freebsd'),
  to allow ssh(1) access when console access is not available (VGA
  or serial).  The default 'root' user password is set to 'root'.

- The /etc/ttys file for arm images now enable both ttyv0 and ttyu0
  by default.

Help from:	many (boot testing, feedback, etc.)
