Move atf-sh from /usr/bin/ to /usr/libexec/
In r266650, we made libatf-c and libatf-c++ private libraries so that no
components outside of the source tree could unintendedly depend on them.
This change does the same for the "atf-sh library" by moving the atf-sh
interpreter from its public location in /usr/bin/ to the private location
in /usr/libexec/. Our build system will ensure that our own test programs
use the right binary, but users won't be able to depend on atf-sh by
"mistake".

Homogenize libatf-* version numbers with upstream.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected. This is just confusing and bound to cause
problems down the road.
Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default. However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.
Some devices (e.g. Intel AHCI and NICs) support quad-word access to
register pairs where two 32-bit registers make up a larger logical
size. Support those access by splitting the quad-word into two
double-words.

When building picobsd, define WITHOUT_OPENSSL and WITHOUT_KERBEROS and

Support "GNU Unifont" format font data
The GNU Unifont .hex format is a text file. Each line represents one

Try to fix DWC OTG regression issues with full and low speed devices:
- Remove double buffering interrupt and isochronous traffic via the
transaction translator. It can be avoided because the DWC OTG will
always delay the start split transactions for interrupt and
isochronous traffic, but will not delay the complete split
transactions, if we set the odd frame bit correctly.
- Need to check the transfer cache field in the device done function
to be sure all allocated channels are freed and not the transfer first
one. This seems to resolve the control endpoint transfer type quirk
which is now removed.
- Make sure any received data upon TX is dumped else RX path will
stop.
- Transmit isochronous data before receiving isochronous data as a
means to optimise the TT schedule.
- Implement a simple TT bandwidth scheduler.
- Cleanup use of old "td->error" variable.
- On interrupt IN traffic via the transaction translator we simply
ignore missed transfer opportunities and silently retry the
transaction upon next available time slot.

The code that combines adjacent ranges for BIO_DELETEs to optimize
trims to the device assumes the list is sorted. Don't apply the
optimization of not sorting the queue when we have SSDs to the
delete_queue, since it causes more discard traffic to the drive. While
one could argue that the higher levels should coalesce the trims,
that's not done today, so some optimization at this level is needed.

Replace gethrtime() with cpu_ticks(), as source of random for the taskqueue

FreeBSD, historically, has always used 8-bit addresses for i2c devices
(7-bit device address << 1), always leaving the room for the read/write bit.
This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.
Also, update the PMIC i2c address on beaglebone* DTS files to match the new
address scheme.
Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).
Remove the unnecessary i2c slave address assignment.
The ti_i2c controller only works in the master mode and the i2c address
passed on iicbus_reset() is used to set the controller slave address when
operating as an i2c slave (which isn't currently supported).
When talking to a slave, the slave address is correctly provided to
ti_i2c_tranfer().
Fix case when vt(4) started w/o driver assigned.
o Always init locks and cv ASAP.
o Initialize driver-independent parts even if driver probing fail.
o Allow to call vt_upgrade anytime, for later loaded drivers.
o New window flag VWF_READY, to track if window already initialized.

o Pass vd as a cookie for kbd_allocate.
o Do not blank window on driver replacement.
