Use `pkg -vv' to obtain ABI for validating a chosen media server (done
prior to diving head-long into a pkg-update(8), et. al). This should
also be more future-proof than what was being done just before this.

Extend loader_delay as-documented in beastie.4th(8) and delay.4th(8), making it available to architectures that do not use or load the beastie
menu. This is reported to save headaches on some PPC systems where unload
followed by load does not produce the desired results wherein if-given
the opportunicy to abort the initial loading sequence, you can customize
the first load.

Yet, another attempt to fix the libm breakage due to the

Fix a bug that prevented `-d' from working as-documented in sysrc(8).
Rather, prevent a bunch of debugging information from spewing onto the
screen when using the `describe' flag (misinterpreted as `debug' by
the automatatic initialization routines).
Instead of modeling the kernel-tools build after the bootstrap tools, build
kernel tools the way cross-tools get built.  This seems to result in the
tool getting installed in the right place.  It also seems more correct in
retrospect, because if a tool emitted code or binary data as part of
building the kernel, it should do so in target-specific ways (endianess,
architecture, whatever).  That issue is moot for aicasm, our only current
tool, but it still seems to be more correct in principle.
Add new `--version' long option for getting the version (good for
comparing against the ports revision).
Add a `-c' option for `check only' to determine if a value is set
(get command) or if the current value is the same as what is desired
(set command). In those cases, the return status is success.
Otherwise, if the variable is unset (get command) or set to a different
value that what is desired (set command), returns with error status.
This is useful for puppet integration as well as everyday scripting.

Fix a bug with `-e' that broke sometime around when I added `-F'. Also,

Build kernel tools along with other tools during world build, as well as
during kernel build (if they didn't get done with world).  This will make

A series of changes tested together as a whole:
+ Add a `-D FILE" command-line option for overriding the path to the
  bsdinstall log file (BSDINSTALL_LOG env var).
+ Document new `-D FILE' in the man page for bsdinstall.
+ If FILE in `-D FILE' begins with a +, debug output goes to stdout
  (interleaved between dialog(1) invocations/output) as well as to FILE
  (minus the leading + of course).
+ If BSDINSTALL_LOG cannot be written, then debugging is disabled (except in
  the case of a leading + in the pathname, wherein debug will still be
  printed to stdout).
+ Update source code formatting style.
+ Fix a dangling participle ("Begun ..." -> "Began ...")
+ Rewrite the docsinstall script (was necessary to abate direct dependency
  on BSDINSTALL_LOG (instead, use fault-tolerant bsdconfig framework which
  displays appropriate errors for package management).
NB: docsinstall is still using pkg(8) after this change.
+ Add additional debug output for dhclient/rtsol/wpa_cliscan
+ Display script errors in a textbox rather than just on stdout
+ Update many coments.
+ Add new f_show_err() API call (like f_show_msg but changes the dialog
  title to "Error")(see bsdconfig's `common.subr').
+ Add new f_eval_catch() API call for executing a command via eval but not
  before logging the command to debug. Several example cases documented in
  API header for function in bsdconfig's `common.subr'.
+ Fix dialog auto-sizing when launched as an rvalue to a pipe for indirected
  scripts (previously would default to 24x80 sizing in this case, now it can
  autosize to full size even when in a pipe chain).
+ Fix bug in f_snprintf if $format argument began with "-"; printf would
  misinterpret as a flag. (this is in bsdcofig's `strings.subr').
+ Add accompanying f_sprintf() and f_vsprintf() to go along with already
  existing f_snprintf() and f_vsnprintf() (see bsdconfig's `strings.subr').
+ Remove some unnecessary default ZFS datasets from the automatic "zfsboot"
  script. Such as: /usr/ports/distfiles /usr/ports/packages /usr/obj /var/db
  /var/empty /var/mail and /var/run (these can all be created as-needed once
  the system is installed).
+ Remove setuid=off for /usr/home (as discussed from last round of CFT).
+ Fix some i18n string violations in "zfsboot".
+ Bolster debugging output in "zfsboot".
+ Fix some string quoting issues in "zfsboot".
+ Fix some variable scope issues in "zfsboot".
+ Change "Create" to "Install" in "zfsboot" main menu.
+ Increase error checking in "zfsboot" (type-check arguments and such).
+ Add call to "graid destroy" killing automatic metadata (part of the series
  of pedantic destructions we do when bootstrapping a new/naked disk).
+ Make judicious use of new f_eval_catch() in "zfsboot".
+ Fixup some variable names for consistency (zfsboot).
+ Fix an underride syntax parameter expansion folly (zfsboot).
+ Confirm layout if not explicitly chosen when blindly proceeding (no
  longer have to touch anything on the ZFS menu if it scares you, just
  choose the omnibus "Install" option at the top and you'll be prompted to
  select vdev type and disks in the layout confirmation dialog).
+ Change numbered menu items to alphabetic for more efficient navigation.
+ Consolidate vdev selection and disk selection into a single stateful
  menu which performs validation and allows backing out to each previous
  menu as you go deeper.
+ Redesign the ``Last Chance'' dialog (still using the same colors, but
  make it conform to a tolerable width and make disks appear in a block-
  quote style indented region).
+ Fix a bug wherein we used the a lowercase variable name by accident
  (actual variable name declared as all-uppercase) at the time of
  initializing fstab(5) (not believed to cause any issues though).
+ Update the geli setup infobox for each provider being initialized
  (not just at the onset -- since each ``geli init'' causes kernel messages
  to push our infobox off-screen).
